 ## [Unreleased]
 
+## [1.24.0/0.46.0/0.0.1-alpha] 2024-02-23
+
+This release is the last to support [Go 1.20].
+The next release will require at least [Go 1.21].
+
+### Added
+
+- Support [Go 1.22]. (#4890)
+- Add exemplar support to `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`. (#4900)
+- Add exemplar support to `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`. (#4900)
+- The `go.opentelemetry.io/otel/log` module is added.
+  This module includes OpenTelemetry Go's implementation of the Logs Bridge API.
+  This module is in an alpha state, it is subject to breaking changes.
+  See our [versioning policy](./VERSIONING.md) for more info. (#4961)
+
+### Fixed
+
+- Fix registration of multiple callbacks when using the global meter provider from `go.opentelemetry.io/otel`. (#4945)
+- Fix negative buckets in output of exponential histograms. (#4956)
+
+## [1.23.1] 2024-02-07
+
+### Fixed
+
+- Register all callbacks passed during observable instrument creation instead of just the last one multiple times in `go.opentelemetry.io/otel/sdk/metric`. (#4888)
+
+## [1.23.0] 2024-02-06
+
+This release contains the first stable, `v1`, release of the following modules:
+
+- `go.opentelemetry.io/otel/bridge/opencensus`
+- `go.opentelemetry.io/otel/bridge/opencensus/test`
+- `go.opentelemetry.io/otel/example/opencensus`
+- `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`
+- `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`
+- `go.opentelemetry.io/otel/exporters/stdout/stdoutmetric`
+
+See our [versioning policy](VERSIONING.md) for more information about these stability guarantees.
+
+### Added
+
+- Add `WithEndpointURL` option to the `exporters/otlp/otlpmetric/otlpmetricgrpc`, `exporters/otlp/otlpmetric/otlpmetrichttp`, `exporters/otlp/otlptrace/otlptracegrpc` and `exporters/otlp/otlptrace/otlptracehttp` packages. (#4808)
+- Experimental exemplar exporting is added to the metric SDK.
+  See [metric documentation](./sdk/metric/internal/x/README.md#exemplars) for more information about this feature and how to enable it. (#4871)
+- `ErrSchemaURLConflict` is added to `go.opentelemetry.io/otel/sdk/resource`.
+  This error is returned when a merge of two `Resource`s with different (non-empty) schema URL is attempted. (#4876)
+
+### Changed
+
+- The `Merge` and `New` functions in `go.opentelemetry.io/otel/sdk/resource` now returns a partial result if there is a schema URL merge conflict.
+  Instead of returning `nil` when two `Resource`s with different (non-empty) schema URLs are merged the merged `Resource`, along with the new `ErrSchemaURLConflict` error, is returned.
+  It is up to the user to decide if they want to use the returned `Resource` or not.
+  It may have desired attributes overwritten or include stale semantic conventions. (#4876)
+
+### Fixed
+
+- Fix `ContainerID` resource detection on systemd when cgroup path has a colon. (#4449)
+- Fix `go.opentelemetry.io/otel/sdk/metric` to cache instruments to avoid leaking memory when the same instrument is created multiple times. (#4820)
+- Fix missing `Mix` and `Max` values for `go.opentelemetry.io/otel/exporters/stdout/stdoutmetric` by introducing `MarshalText` and `MarshalJSON` for the `Extrema` type in `go.opentelemetry.io/sdk/metric/metricdata`. (#4827)
+
+## [1.23.0-rc.1] 2024-01-18
+
+This is a release candidate for the v1.23.0 release.
+That release is expected to include the `v1` release of the following modules:
+
+- `go.opentelemetry.io/otel/bridge/opencensus`
+- `go.opentelemetry.io/otel/bridge/opencensus/test`
+- `go.opentelemetry.io/otel/example/opencensus`
+- `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`
+- `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`
+- `go.opentelemetry.io/otel/exporters/stdout/stdoutmetric`
+
+See our [versioning policy](VERSIONING.md) for more information about these stability guarantees.
+
+## [1.22.0/0.45.0] 2024-01-17
+
+### Added
+
+- The `go.opentelemetry.io/otel/semconv/v1.22.0` package.
+  The package contains semantic conventions from the `v1.22.0` version of the OpenTelemetry Semantic Conventions. (#4735)
+- The `go.opentelemetry.io/otel/semconv/v1.23.0` package.
+  The package contains semantic conventions from the `v1.23.0` version of the OpenTelemetry Semantic Conventions. (#4746)
+- The `go.opentelemetry.io/otel/semconv/v1.23.1` package.
+  The package contains semantic conventions from the `v1.23.1` version of the OpenTelemetry Semantic Conventions. (#4749)
+- The `go.opentelemetry.io/otel/semconv/v1.24.0` package.
+  The package contains semantic conventions from the `v1.24.0` version of the OpenTelemetry Semantic Conventions. (#4770)
+- Add `WithResourceAsConstantLabels` option to apply resource attributes for every metric emitted by the Prometheus exporter. (#4733)
+- Experimental cardinality limiting is added to the metric SDK.
+  See [metric documentation](./sdk/metric/internal/x/README.md#cardinality-limit) for more information about this feature and how to enable it. (#4457)
+- Add `NewMemberRaw` and `NewKeyValuePropertyRaw` in `go.opentelemetry.io/otel/baggage`. (#4804)
+
+### Changed
+
+- Upgrade all use of `go.opentelemetry.io/otel/semconv` to use `v1.24.0`. (#4754)
+- Update transformations in `go.opentelemetry.io/otel/exporters/zipkin` to follow `v1.24.0` version of the OpenTelemetry specification. (#4754)
+- Record synchronous measurements when the passed context is canceled instead of dropping in `go.opentelemetry.io/otel/sdk/metric`.
+  If you do not want to make a measurement when the context is cancelled, you need to handle it yourself (e.g  `if ctx.Err() != nil`). (#4671)
+- Improve `go.opentelemetry.io/otel/trace.TraceState`'s performance. (#4722)
+- Improve `go.opentelemetry.io/otel/propagation.TraceContext`'s performance. (#4721)

+- `Member.String` in `go.opentelemetry.io/otel/baggage` percent-encodes only when necessary. (#4775)
+- Improve `go.opentelemetry.io/otel/trace.Span`'s performance when adding multiple attributes. (#4818)
+- `Property.Value` in `go.opentelemetry.io/otel/baggage` now returns a raw string instead of a percent-encoded value. (#4804)
+
+### Fixed
+

+- Fix whitespace encoding of `Member.String` in `go.opentelemetry.io/otel/baggage`. (#4756)
+- Fix observable not registered error when the asynchronous instrument has a drop aggregation in `go.opentelemetry.io/otel/sdk/metric`. (#4772)
+- Fix baggage item key so that it is not canonicalized in `go.opentelemetry.io/otel/bridge/opentracing`. (#4776)
+- Fix `go.opentelemetry.io/otel/bridge/opentracing` to properly handle baggage values that requires escaping during propagation. (#4804)
+- Fix a bug where using multiple readers resulted in incorrect asynchronous counter values in `go.opentelemetry.io/otel/sdk/metric`. (#4742)

+
+## [1.20.0/0.43.0] 2023-11-10
+
+This release brings a breaking change for custom trace API implementations. Some interfaces (`TracerProvider`, `Tracer`, `Span`) now embed the `go.opentelemetry.io/otel/trace/embedded` types. Implementors need to update their implementations based on what they want the default behavior to be. See the "API Implementations" section of the [trace API] package documentation for more information about how to accomplish this.

+  - `InstrumentKindAsyncGauge` is renamed to `InstrumentKindObservableGauge`
+- The `RegisterCallback` method of the `Meter` in `go.opentelemetry.io/otel/metric` changed.
+  - The named `Callback` replaces the inline function parameter. (#3564)
+  - `Callback` is required to return an error. (#3576)
+  - `Callback` accepts the added `Observer` parameter added.
+    This new parameter is used by `Callback` implementations to observe values for asynchronous instruments instead of calling the `Observe` method of the instrument directly. (#3584)
+  - The slice of `instrument.Asynchronous` is now passed as a variadic argument. (#3587)
+- The exporter from `go.opentelemetry.io/otel/exporters/zipkin` is updated to use the `v1.16.0` version of semantic conventions.
+  This means it no longer uses the removed `net.peer.ip` or `http.host` attributes to determine the remote endpoint.
+  Instead it uses the `net.sock.peer` attributes. (#3581)
+- The `Min` and `Max` fields of the `HistogramDataPoint` in `go.opentelemetry.io/otel/sdk/metric/metricdata` are now defined with the added `Extrema` type instead of a `*float64`. (#3487)
+
+### Fixed
+
+- Asynchronous instruments that use sum aggregators and attribute filters correctly add values from equivalent attribute sets that have been filtered. (#3439, #3549)
+- The `RegisterCallback` method of the `Meter` from `go.opentelemetry.io/otel/sdk/metric` only registers a callback for instruments created by that meter.
+  Trying to register a callback with instruments from a different meter will result in an error being returned. (#3584)

+
+### Added
+
+- The `WithView` `Option` is added to the `go.opentelemetry.io/otel/sdk/metric` package.
+   This option is used to configure the view(s) a `MeterProvider` will use for all `Reader`s that are registered with it. (#3387)
+- Add Instrumentation Scope and Version as info metric and label in Prometheus exporter.
+  This can be disabled using the `WithoutScopeInfo()` option added to that package.(#3273, #3357)
+- OTLP exporters now recognize: (#3363)
+  - `OTEL_EXPORTER_OTLP_INSECURE`
+  - `OTEL_EXPORTER_OTLP_TRACES_INSECURE`
+  - `OTEL_EXPORTER_OTLP_METRICS_INSECURE`

+- The `AssertHasAttributes` allows instrument authors to test that datapoints returned have appropriate attributes. (#3487)
+
+### Changed
+
+- The `"go.opentelemetry.io/otel/sdk/metric".WithReader` option no longer accepts views to associate with the `Reader`.
+   Instead, views are now registered directly with the `MeterProvider` via the new `WithView` option.
+   The views registered with the `MeterProvider` apply to all `Reader`s. (#3387)
+- The `Temporality(view.InstrumentKind) metricdata.Temporality` and `Aggregation(view.InstrumentKind) aggregation.Aggregation` methods are added to the `"go.opentelemetry.io/otel/sdk/metric".Exporter` interface. (#3260)
+- The `Temporality(view.InstrumentKind) metricdata.Temporality` and `Aggregation(view.InstrumentKind) aggregation.Aggregation` methods are added to the `"go.opentelemetry.io/otel/exporters/otlp/otlpmetric".Client` interface. (#3260)
+- The `WithTemporalitySelector` and `WithAggregationSelector` `ReaderOption`s have been changed to `ManualReaderOption`s in the `go.opentelemetry.io/otel/sdk/metric` package. (#3260)
+- The periodic reader in the `go.opentelemetry.io/otel/sdk/metric` package now uses the temporality and aggregation selectors from its configured exporter instead of accepting them as options. (#3260)
+
+### Fixed
+
+- The `go.opentelemetry.io/otel/exporters/prometheus` exporter fixes duplicated `_total` suffixes. (#3369)
+- Remove comparable requirement for `Reader`s. (#3387)
+- Cumulative metrics from the OpenCensus bridge (`go.opentelemetry.io/otel/bridge/opencensus`) are defined as monotonic sums, instead of non-monotonic. (#3389)
+- Asynchronous counters (`Counter` and `UpDownCounter`) from the metric SDK now produce delta sums when configured with delta temporality. (#3398)

+
+### Deprecated
+
+- The `go.opentelemetry.io/otel/sdk/metric/view` package is deprecated.
+  Use `Instrument`, `InstrumentKind`, `View`, and `NewView` in `go.opentelemetry.io/otel/sdk/metric` instead. (#3476)
+
+## [1.11.1/0.33.0] 2022-10-19
+
+### Added
+
+- The Prometheus exporter in `go.opentelemetry.io/otel/exporters/prometheus` registers with a Prometheus registerer on creation.
+   By default, it will register with the default Prometheus registerer.
+   A non-default registerer can be used by passing the `WithRegisterer` option. (#3239)
+- Added the `WithAggregationSelector` option to the `go.opentelemetry.io/otel/exporters/prometheus` package to change the default `AggregationSelector` used. (#3341)
+- The Prometheus exporter in `go.opentelemetry.io/otel/exporters/prometheus` converts the `Resource` associated with metric exports into a `target_info` metric. (#3285)
+
+### Changed
+
+- The `"go.opentelemetry.io/otel/exporters/prometheus".New` function is updated to return an error.
+   It will return an error if the exporter fails to register with Prometheus. (#3239)
+
+### Fixed
+
+- The URL-encoded values from the `OTEL_RESOURCE_ATTRIBUTES` environment variable are decoded. (#2963)
+- The `baggage.NewMember` function decodes the `value` parameter instead of directly using it.
+   This fixes the implementation to be compliant with the W3C specification. (#3226)
+- Slice attributes of the `attribute` package are now comparable based on their value, not instance. (#3108 #3252)
+- The `Shutdown` and `ForceFlush` methods of the `"go.opentelemetry.io/otel/sdk/trace".TraceProvider` no longer return an error when no processor is registered. (#3268)
+- The Prometheus exporter in `go.opentelemetry.io/otel/exporters/prometheus` cumulatively sums histogram buckets. (#3281)
+- The sum of each histogram data point is now uniquely exported by the `go.opentelemetry.io/otel/exporters/otlpmetric` exporters. (#3284, #3293)
+- Recorded values for asynchronous counters (`Counter` and `UpDownCounter`) are interpreted as exact, not incremental, sum values by the metric SDK. (#3350, #3278)
+- `UpDownCounters` are now correctly output as Prometheus gauges in the `go.opentelemetry.io/otel/exporters/prometheus` exporter. (#3358)
+- The Prometheus exporter in `go.opentelemetry.io/otel/exporters/prometheus` no longer describes the metrics it will send to Prometheus on startup.
+   Instead the exporter is defined as an "unchecked" collector for Prometheus.
+   This fixes the `reader is not registered` warning currently emitted on startup. (#3291 #3342)
+- The `go.opentelemetry.io/otel/exporters/prometheus` exporter now correctly adds `_total` suffixes to counter metrics. (#3360)
+- The `go.opentelemetry.io/otel/exporters/prometheus` exporter now adds a unit suffix to metric names.
+   This can be disabled using the `WithoutUnits()` option added to that package. (#3352)
+
+## [1.11.0/0.32.3] 2022-10-12
+
+### Added
+
+- Add default User-Agent header to OTLP exporter requests (`go.opentelemetry.io/otel/exporters/otlptrace/otlptracegrpc` and `go.opentelemetry.io/otel/exporters/otlptrace/otlptracehttp`). (#3261)
+

+
+### Fixed
+
+- Use default view if instrument does not match any registered view of a reader. (#3224, #3237)
+- Return the same instrument every time a user makes the exact same instrument creation call. (#3229, #3251)
+- Return the existing instrument when a view transforms a creation call to match an existing instrument. (#3240, #3251)
+- Log a warning when a conflicting instrument (e.g. description, unit, data-type) is created instead of returning an error. (#3251)
+- The OpenCensus bridge no longer sends empty batches of metrics. (#3263)
+
+## [0.32.1] Metric SDK (Alpha) - 2022-09-22

+  This replaces the use of the now deprecated `InstrumentationLibrary` and `InstrumentationLibrarySpans` types and fields in the proto library with the equivalent `InstrumentationScope` and `ScopeSpans`. (#2748)
+
+## [1.6.1] - 2022-03-28
+
+### Fixed
+
+- The `go.opentelemetry.io/otel/schema/*` packages now use the correct schema URL for their `SchemaURL` constant.
+  Instead of using `"https://opentelemetry.io/schemas/v<version>"` they now use the correct URL without a `v` prefix, `"https://opentelemetry.io/schemas/<version>"`. (#2743, #2744)
+
+### Security
+
+- Upgrade `go.opentelemetry.io/proto/otlp` from `v0.12.0` to `v0.12.1`.
+  This includes an indirect upgrade of `github.com/grpc-ecosystem/grpc-gateway` which resolves [a vulnerability](https://nvd.nist.gov/vuln/detail/CVE-2019-11254) from `gopkg.in/yaml.v2` in version `v2.2.3`. (#2724, #2728)
+
+## [1.6.0/0.28.0] - 2022-03-23
+
+### ⚠️ Notice ⚠️
+
+This update is a breaking change of the unstable Metrics API.
+Code instrumented with the `go.opentelemetry.io/otel/metric` will need to be modified.
+
+### Added
+
+- Add metrics exponential histogram support.
+  New mapping functions have been made available in `sdk/metric/aggregator/exponential/mapping` for other OpenTelemetry projects to take dependencies on. (#2502)
+- Add Go 1.18 to our compatibility tests. (#2679)
+- Allow configuring the Sampler with the `OTEL_TRACES_SAMPLER` and `OTEL_TRACES_SAMPLER_ARG` environment variables. (#2305, #2517)
+- Add the `metric/global` for obtaining and setting the global `MeterProvider`. (#2660)
+
+### Changed
+
+- The metrics API has been significantly changed to match the revised OpenTelemetry specification.
+  High-level changes include:
+
+  - Synchronous and asynchronous instruments are now handled by independent `InstrumentProvider`s.
+    These `InstrumentProvider`s are managed with a `Meter`.
+  - Synchronous and asynchronous instruments are grouped into their own packages based on value types.
+  - Asynchronous callbacks can now be registered with a `Meter`.
+
+  Be sure to check out the metric module documentation for more information on how to use the revised API. (#2587, #2660)
+
+### Fixed
+
+- Fallback to general attribute limits when span specific ones are not set in the environment. (#2675, #2677)
+
+## [1.5.0] - 2022-03-16
+
+### Added
+
+- Log the Exporters configuration in the TracerProviders message. (#2578)
+- Added support to configure the span limits with environment variables.
+  The following environment variables are supported. (#2606, #2637)
+  - `OTEL_SPAN_ATTRIBUTE_VALUE_LENGTH_LIMIT`
+  - `OTEL_SPAN_ATTRIBUTE_COUNT_LIMIT`
+  - `OTEL_SPAN_EVENT_COUNT_LIMIT`
+  - `OTEL_EVENT_ATTRIBUTE_COUNT_LIMIT`
+  - `OTEL_SPAN_LINK_COUNT_LIMIT`
+  - `OTEL_LINK_ATTRIBUTE_COUNT_LIMIT`
+
+  If the provided environment variables are invalid (negative), the default values would be used.
+- Rename the `gc` runtime name to `go` (#2560)
+- Add resource container ID detection. (#2418)
+- Add span attribute value length limit.
+  The new `AttributeValueLengthLimit` field is added to the `"go.opentelemetry.io/otel/sdk/trace".SpanLimits` type to configure this limit for a `TracerProvider`.
+  The default limit for this resource is "unlimited". (#2637)
+- Add the `WithRawSpanLimits` option to `go.opentelemetry.io/otel/sdk/trace`.
+  This option replaces the `WithSpanLimits` option.
+  Zero or negative values will not be changed to the default value like `WithSpanLimits` does.
+  Setting a limit to zero will effectively disable the related resource it limits and setting to a negative value will mean that resource is unlimited.
+  Consequentially, limits should be constructed using `NewSpanLimits` and updated accordingly. (#2637)
+
+### Changed
+
+- Drop oldest tracestate `Member` when capacity is reached. (#2592)
+- Add event and link drop counts to the exported data from the `oltptrace` exporter. (#2601)
+- Unify path cleaning functionally in the `otlpmetric` and `otlptrace` configuration. (#2639)
+- Change the debug message from the `sdk/trace.BatchSpanProcessor` to reflect the count is cumulative. (#2640)
+- Introduce new internal `envconfig` package for OTLP exporters. (#2608)
+- If `http.Request.Host` is empty, fall back to use `URL.Host` when populating `http.host` in the `semconv` packages. (#2661)
+
+### Fixed
+
+- Remove the OTLP trace exporter limit of SpanEvents when exporting. (#2616)
+- Default to port `4318` instead of `4317` for the `otlpmetrichttp` and `otlptracehttp` client. (#2614, #2625)
+- Unlimited span limits are now supported (negative values). (#2636, #2637)
+
+### Deprecated
+
+- Deprecated `"go.opentelemetry.io/otel/sdk/trace".WithSpanLimits`.
+  Use `WithRawSpanLimits` instead.
+  That option allows setting unlimited and zero limits, this option does not.
+  This option will be kept until the next major version incremented release. (#2637)
+
+## [1.4.1] - 2022-02-16
+
+### Fixed
+
+- Fix race condition in reading the dropped spans number for the `BatchSpanProcessor`. (#2615)
+
+## [1.4.0] - 2022-02-11
+
+### Added
+
+- Use `OTEL_EXPORTER_ZIPKIN_ENDPOINT` environment variable to specify zipkin collector endpoint. (#2490)
+- Log the configuration of `TracerProvider`s, and `Tracer`s for debugging.
+  To enable use a logger with Verbosity (V level) `>=1`. (#2500)
+- Added support to configure the batch span-processor with environment variables.
+  The following environment variables are used. (#2515)
+  - `OTEL_BSP_SCHEDULE_DELAY`
+  - `OTEL_BSP_EXPORT_TIMEOUT`
+  - `OTEL_BSP_MAX_QUEUE_SIZE`.
+  - `OTEL_BSP_MAX_EXPORT_BATCH_SIZE`
+
+### Changed
+
+- Zipkin exporter exports `Resource` attributes in the `Tags` field. (#2589)
+
+### Deprecated
+
+- Deprecate module the `go.opentelemetry.io/otel/sdk/export/metric`.
+  Use the `go.opentelemetry.io/otel/sdk/metric` module instead. (#2382)
+- Deprecate `"go.opentelemetry.io/otel/sdk/metric".AtomicFieldOffsets`. (#2445)
+
+### Fixed
+
+- Fixed the instrument kind for noop async instruments to correctly report an implementation. (#2461)
+- Fix UDP packets overflowing with Jaeger payloads. (#2489, #2512)
+- Change the `otlpmetric.Client` interface's `UploadMetrics` method to accept a single `ResourceMetrics` instead of a slice of them. (#2491)
+- Specify explicit buckets in Prometheus example, fixing issue where example only has `+inf` bucket. (#2419, #2493)
+- W3C baggage will now decode urlescaped values. (#2529)
+- Baggage members are now only validated once, when calling `NewMember` and not also when adding it to the baggage itself. (#2522)
+- The order attributes are dropped from spans in the `go.opentelemetry.io/otel/sdk/trace` package when capacity is reached is fixed to be in compliance with the OpenTelemetry specification.
+  Instead of dropping the least-recently-used attribute, the last added attribute is dropped.
+  This drop order still only applies to attributes with unique keys not already contained in the span.
+  If an attribute is added with a key already contained in the span, that attribute is updated to the new value being added. (#2576)
+
+### Removed
+
+- Updated `go.opentelemetry.io/proto/otlp` from `v0.11.0` to `v0.12.0`. This version removes a number of deprecated methods. (#2546)
+  - [`Metric.GetIntGauge()`](https://pkg.go.dev/go.opentelemetry.io/proto/otlp@v0.11.0/metrics/v1#Metric.GetIntGauge)
+  - [`Metric.GetIntHistogram()`](https://pkg.go.dev/go.opentelemetry.io/proto/otlp@v0.11.0/metrics/v1#Metric.GetIntHistogram)

 Otherwise, stable interfaces MUST NOT be modified.
 
+#### How to Change Specification Interfaces
+
+When an API change must be made, we will update the SDK with the new method one
+release before the API change. This will allow the SDK one version before the
+API change to work seamlessly with the new API.
+
+If an incompatible version of the SDK is used with the new API the application
+will fail to compile.
+
+#### How Not to Change Specification Interfaces
+
+We have explored using a v2 of the API to change interfaces and found that there
+was no way to introduce a v2 and have it work seamlessly with the v1 of the API.
+Problems happened with libraries that upgraded to v2 when an application did not,
+and would not produce any telemetry.
+
+More detail of the approaches considered and their limitations can be found in
+the [Use a V2 API to evolve interfaces](https://github.com/open-telemetry/opentelemetry-go/issues/3920)

+### Testing
+
+The tests should never leak goroutines.
+
+Use the term `ConcurrentSafe` in the test name when it aims to verify the
+absence of race conditions.
+
+### Internal packages
+
+The use of internal packages should be scoped to a single module. A sub-module
+should never import from a parent internal package. This creates a coupling
+between the two modules where a user can upgrade the parent without the child
+and if the internal package API has changed it will fail to upgrade[^3].
+
+There are two known exceptions to this rule:
+
+- `go.opentelemetry.io/otel/internal/global`
+  - This package manages global state for all of opentelemetry-go. It needs to
+  be a single package in order to ensure the uniqueness of the global state.
+- `go.opentelemetry.io/otel/internal/baggage`
+  - This package provides values in a `context.Context` that need to be
+  recognized by `go.opentelemetry.io/otel/baggage` and
+  `go.opentelemetry.io/otel/bridge/opentracing` but remain private.
+
+If you have duplicate code in multiple modules, make that code into a Go
+template stored in `go.opentelemetry.io/otel/internal/shared` and use [gotmpl]
+to render the templates in the desired locations. See [#4404] for an example of
+this.
+
+[^3]: https://github.com/open-telemetry/opentelemetry-go/issues/3548
+
+### Ignoring context cancellation
+
+OpenTelemetry API implementations need to ignore the cancellation of the context that are
+passed when recording a value (e.g. starting a span, recording a measurement, emitting a log).
+Recording methods should not return an error describing the cancellation state of the context
+when they complete, nor should they abort any work.
+
+This rule may not apply if the OpenTelemetry specification defines a timeout mechanism for
+the method. In that case the context cancellation can be used for the timeout with the
+restriction that this behavior is documented for the method. Otherwise, timeouts
+are expected to be handled by the user calling the API, not the implementation.
+
+Stoppage of the telemetry pipeline is handled by calling the appropriate `Shutdown` method
+of a provider. It is assumed the context passed from a user is not used for this purpose.
+
+Outside of the direct recording of telemetry from the API (e.g. exporting telemetry,
+force flushing telemetry, shutting down a signal provider) the context cancellation
+should be honored. This means all work done on behalf of the user provided context
+should be canceled.

 ### Compatibility
 
-OpenTelemetry-Go attempts to track the current supported versions of the
-[Go language](https://golang.org/doc/devel/release#policy). The release
-schedule after a new minor version of go is as follows:
+OpenTelemetry-Go ensures compatibility with the current supported versions of
+the [Go language](https://golang.org/doc/devel/release#policy):
+
+> Each major Go release is supported until there are two newer major releases.
+> For example, Go 1.5 was supported until the Go 1.7 release, and Go 1.6 was supported until the Go 1.8 release.
+
+For versions of Go that are no longer supported upstream, opentelemetry-go will
+stop ensuring compatibility with these versions in the following manner:
 
-- The first release or one month, which ever is sooner, will add build steps for the new go version.
-- The first release after three months will remove support for the oldest go version.
+- A minor release of opentelemetry-go will be made to add support for the new
+  supported release of Go.
+- The following minor release of opentelemetry-go will remove compatibility
+  testing for the oldest (now archived upstream) version of Go. This, and
+  future, releases of opentelemetry-go may include features only supported by
+  the currently supported versions of Go.

 ## Semantic Convention Generation
 
-If a new version of the OpenTelemetry Specification has been released it will be necessary to generate a new
-semantic convention package from the YAML definitions in the specification repository. There is a `semconvgen` utility
-installed by `make tools` that can be used to generate the a package with the name matching the specification
-version number under the `semconv` package. This will ideally be done soon after the specification release is
-tagged. Make sure that the specification repo contains a checkout of the the latest tagged release so that the
-generated files match the released semantic conventions.
+New versions of the [OpenTelemetry Semantic Conventions] mean new versions of the `semconv` package need to be generated.
+The `semconv-generate` make target is used for this.
 
-There are currently two categories of semantic conventions that must be generated, `resource` and `trace`.
+1. Checkout a local copy of the [OpenTelemetry Semantic Conventions] to the desired release tag.
+2. Pull the latest `otel/semconvgen` image: `docker pull otel/semconvgen:latest`
+3. Run the `make semconv-generate ...` target from this repository.
 
-```
-.tools/semconvgen -i /path/to/specification/repo/semantic_conventions/resource -t semconv/template.j2
-.tools/semconvgen -i /path/to/specification/repo/semantic_conventions/trace -t semconv/template.j2
+For example,
+
+```sh
+export TAG="v1.21.0" # Change to the release version you are generating.
+export OTEL_SEMCONV_REPO="/absolute/path/to/opentelemetry/semantic-conventions"
+docker pull otel/semconvgen:latest
+make semconv-generate # Uses the exported TAG and OTEL_SEMCONV_REPO.
 ```
 
-Using default values for all options other than `input` will result in using the `template.j2` template to
-generate `resource.go` and `trace.go` in `/path/to/otelgo/repo/semconv/<version>`.
+This should create a new sub-package of [`semconv`](./semconv).
+Ensure things look correct before submitting a pull request to include the addition.
 
-There are several ancillary files that are not generated and should be copied into the new package from the
-prior package, with updates made as appropriate to canonical import path statements and constant values.
-These files include:
+## Breaking changes validation
 
-* doc.go
-* exception.go
-* http(_test)?.go
-* schema.go
+You can run `make gorelease` that runs [gorelease](https://pkg.go.dev/golang.org/x/exp/cmd/gorelease) to ensure that there are no unwanted changes done in the public API.
 
-Uses of the previous schema version in this repository should be updated to use the newly generated version.
-No tooling for this exists at present, so use find/replace in your editor of choice or craft a `grep | sed`
-pipeline if you like living on the edge.
+You can check/report problems with `gorelease` [here](https://golang.org/issues/26420).

-# OpenCensus Bridge
-
-The OpenCensus Bridge helps facilitate the migration of an application from OpenCensus to OpenTelemetry.
-
-## Caveat about OpenCensus
-
-Installing a metric or tracing bridge will cause OpenCensus telemetry to be exported by OpenTelemetry exporters.  Since OpenCensus telemetry uses globals, installing a bridge will result in telemetry collection from _all_ libraries that use OpenCensus, including some you may not expect.  For example ([#1928](https://github.com/open-telemetry/opentelemetry-go/issues/1928)), if a client library generates traces with OpenCensus, installing the bridge will cause those traces to be exported by OpenTelemetry.
-
-## Tracing
-
-### The Problem: Mixing OpenCensus and OpenTelemetry libraries
-
-In a perfect world, one would simply migrate their entire go application --including custom instrumentation, libraries, and exporters-- from OpenCensus to OpenTelemetry all at once.  In the real world, dependency constraints, third-party ownership of libraries, or other reasons may require mixing OpenCensus and OpenTelemetry libraries in a single application.
-
-However, if you create the following spans in a go application:
-
-```go
-ctx, ocSpan := opencensus.StartSpan(context.Background(), "OuterSpan")
-defer ocSpan.End()
-ctx, otSpan := opentelemetryTracer.Start(ctx, "MiddleSpan")
-defer otSpan.End()
-ctx, ocSpan := opencensus.StartSpan(ctx, "InnerSpan")
-defer ocSpan.End()
-```
-
-OpenCensus reports (to OpenCensus exporters):
-
-```
-[--------OuterSpan------------]
-    [----InnerSpan------]
-```
-
-OpenTelemetry reports (to OpenTelemetry exporters):
-
-```
-   [-----MiddleSpan--------]
-```
-
-Instead, I would prefer (to a single set of exporters):
-
-```
-[--------OuterSpan------------]
-   [-----MiddleSpan--------]
-    [----InnerSpan------]
-```
-
-### The bridge solution
-
-The bridge implements the OpenCensus trace API using OpenTelemetry.  This would cause, for example, a span recorded with OpenCensus' `StartSpan()` method to be equivalent to recording a span using OpenTelemetry's `tracer.Start()` method.  Funneling all tracing API calls to OpenTelemetry APIs results in the desired unified span hierarchy.
-
-### User Journey
-
-Starting from an application using entirely OpenCensus APIs:
-
-1. Instantiate OpenTelemetry SDK and Exporters
-2. Override OpenCensus' DefaultTracer with the bridge
-3. Migrate libraries individually from OpenCensus to OpenTelemetry
-4. Remove OpenCensus exporters and configuration
-
-To override OpenCensus' DefaultTracer with the bridge:
-
-```go
-import (
-	octrace "go.opencensus.io/trace"
-	"go.opentelemetry.io/otel/bridge/opencensus"
-	"go.opentelemetry.io/otel"
-)
-
-tracer := otel.GetTracerProvider().Tracer("bridge")
-octrace.DefaultTracer = opencensus.NewTracer(tracer)
-```
-
-Be sure to set the `Tracer` name to your instrumentation package name instead of `"bridge"`.

-OpenCensus and OpenTelemetry APIs are not entirely compatible.  If the bridge finds any incompatibilities, it will log them.  Incompatibilities include:
-
-* Custom OpenCensus Samplers specified during StartSpan are ignored.
-* Links cannot be added to OpenCensus spans.
-* OpenTelemetry Debug or Deferred trace flags are dropped after an OpenCensus span is created.
-
-## Metrics
-
-### The problem: mixing libraries without mixing pipelines
-
-The problem for monitoring is simpler than the problem for tracing, since there
-are no context propagation issues to deal with. However, it still is difficult
-for users to migrate an entire applications' monitoring at once. It
-should be possible to send metrics generated by OpenCensus libraries to an
-OpenTelemetry pipeline so that migrating a metric does not require maintaining
-separate export pipelines for OpenCensus and OpenTelemetry.
-
-### The Exporter "wrapper" solution
-
-The solution we use here is to allow wrapping an OpenTelemetry exporter such
-that it implements the OpenCensus exporter interfaces. This allows a single
-exporter to be used for metrics from *both* OpenCensus and OpenTelemetry.
-
-### User Journey
-
-Starting from an application using entirely OpenCensus APIs:
-
-1. Instantiate OpenTelemetry SDK and Exporters.
-2. Replace OpenCensus exporters with a wrapped OpenTelemetry exporter from step 1.
-3. Migrate libraries individually from OpenCensus to OpenTelemetry
-4. Remove OpenCensus Exporters and configuration.
-
-For example, to swap out the OpenCensus logging exporter for the OpenTelemetry stdout exporter:
-
-```go
-import (
-	"go.opencensus.io/metric/metricexport"
-	"go.opentelemetry.io/otel/bridge/opencensus"
-	"go.opentelemetry.io/otel/exporters/stdout"
-	"go.opentelemetry.io/otel"
-)
-// With OpenCensus, you could have previously configured the logging exporter like this:
-//       import logexporter "go.opencensus.io/examples/exporter"
-//       exporter, _ := logexporter.NewLogExporter(logexporter.Options{})
-// Instead, we can create an equivalent using the OpenTelemetry stdout exporter:
-openTelemetryExporter, _ := stdout.New(stdout.WithPrettyPrint())
-exporter := opencensus.NewMetricExporter(openTelemetryExporter)
-
-// Use the wrapped OpenTelemetry exporter like you normally would with OpenCensus
-intervalReader, _ := metricexport.NewIntervalReader(&metricexport.Reader{}, exporter)
-intervalReader.Start()
-```

 // Package opencensus provides a migration bridge from OpenCensus to
-// OpenTelemetry. The NewTracer function should be used to create an
-// OpenCensus Tracer from an OpenTelemetry Tracer. This Tracer can be use in

-// spans for traces. These spans will be exported by the OpenTelemetry
-// TracerProvider the original OpenTelemetry Tracer came from.
+// OpenTelemetry for metrics and traces. The bridge incorporates metrics and
+// traces from OpenCensus into the OpenTelemetry SDK, combining them with
+// metrics and traces from OpenTelemetry instrumentation.
 //
-// There are known limitations to this bridge:
+// # Migration Guide
 //
-// - The AddLink method for OpenCensus Spans is not compatible with the
-// OpenTelemetry Span. No link can be added to an OpenTelemetry Span once it
-// is started. Any calls to this method for the OpenCensus Span will result
-// in an error being sent to the OpenTelemetry default ErrorHandler.
+// For most applications, it would be difficult to migrate an application
+// from OpenCensus to OpenTelemetry all-at-once. Libraries used by the
+// application may still be using OpenCensus, and the application itself may
+// have many lines of instrumentation.
 //
-// - The NewContext method of the OpenCensus Tracer cannot embed an OpenCensus
-// Span in a context unless that Span was created by that Tracer.
+// Bridges help in this situation by allowing your application to have "mixed"
+// instrumentation, while incorporating all instrumentation into a single
+// export path. To migrate with bridges, a user would:
 //
-// - Conversion of custom OpenCensus Samplers to OpenTelemetry is not
-// implemented. An error will be sent to the OpenTelemetry default
-// ErrorHandler if this is attempted.
+//  1. Configure the OpenTelemetry SDK for metrics and traces, with the OpenTelemetry exporters matching to your current OpenCensus exporters.
+//  2. Install this OpenCensus bridge, which sends OpenCensus telemetry to your new OpenTelemetry exporters.
+//  3. Over time, migrate your instrumentation from OpenCensus to OpenTelemetry.
+//  4. Once all instrumentation is migrated, remove the OpenCensus bridge.
+//
+// With this approach, you can migrate your telemetry, including in dependent
+// libraries over time without disruption.
+//
+// # Warnings
+//
+// Installing a metric or tracing bridge will cause OpenCensus telemetry to be
+// exported by OpenTelemetry exporters. Since OpenCensus telemetry uses globals,
+// installing a bridge will result in telemetry collection from _all_ libraries
+// that use OpenCensus, including some you may not expect, such as the
+// telemetry exporter itself.
+//
+// # Limitations
+//
+// There are known limitations to the trace bridge:
+//
+//   - The AddLink method for OpenCensus Spans is ignored, and an error is sent
+//     to the OpenTelemetry ErrorHandler.
+//   - The NewContext method of the OpenCensus Tracer cannot embed an OpenCensus
+//     Span in a context unless that Span was created by that Tracer.
+//   - Conversion of custom OpenCensus Samplers to OpenTelemetry is not
+//     implemented, and An error will be sent to the OpenTelemetry ErrorHandler.
+//
+// There are known limitations to the metric bridge:
+//   - GaugeDistribution-typed metrics are dropped
+//   - Histogram's SumOfSquaredDeviation field is dropped

+# OpenTelemetry/OpenTracing Bridge
+
+## Getting started
+
+`go get go.opentelemetry.io/otel/bridge/opentracing`
+
+Assuming you have configured an OpenTelemetry `TracerProvider`, these will be the steps to follow to wire up the bridge:
+
+```go
+import (
+	"go.opentelemetry.io/otel"
+	otelBridge "go.opentelemetry.io/otel/bridge/opentracing"
+)
+
+func main() {
+	/* Create tracerProvider and configure OpenTelemetry ... */
+	
+	otelTracer := tracerProvider.Tracer("tracer_name")
+	// Use the bridgeTracer as your OpenTracing tracer.
+	bridgeTracer, wrapperTracerProvider := otelBridge.NewTracerPair(otelTracer)
+	// Set the wrapperTracerProvider as the global OpenTelemetry
+	// TracerProvider so instrumentation will use it by default.
+	otel.SetTracerProvider(wrapperTracerProvider)
+
+	/* ... */
+}
+```
+
+## Interop from trace context from OpenTracing to OpenTelemetry
+
+In order to get OpenTracing spans properly into the OpenTelemetry context, so they can be propagated (both internally, and externally), you will need to explicitly use the `BridgeTracer` for creating your OpenTracing spans, rather than a bare OpenTracing `Tracer` instance.
+
+When you have started an OpenTracing Span, make sure the OpenTelemetry knows about it like this:
+
+```go
+	ctxWithOTSpan := opentracing.ContextWithSpan(ctx, otSpan)
+	ctxWithOTAndOTelSpan := bridgeTracer.ContextWithSpanHook(ctxWithOTSpan, otSpan)
+	// Propagate the otSpan to both OpenTracing and OpenTelemetry
+	// instrumentation by using the ctxWithOTAndOTelSpan context.
+```
+
+## Extended Functionality
+
+The bridge functionality can be extended beyond the OpenTracing API.
+
+Any [`trace.SpanContext`](https://pkg.go.dev/go.opentelemetry.io/otel/trace#SpanContext) method can be accessed as following:
+
+```go
+type spanContextProvider interface {
+	IsSampled() bool
+	TraceID() trace.TraceID
+	SpanID() trace.SpanID
+	TraceFlags() trace.TraceFlags
+	... // any other available method can be added here to access it
+}
+
+var sc opentracing.SpanContext = ...
+if s, ok := sc.(spanContextProvider); ok {
+	// Use TraceID by s.TraceID()
+	// Use SpanID by s.SpanID()
+	// Use TraceFlags by s.TraceFlags()
+	...
+}
+```

+# OpenTelemetry Exporters
+
+Once the OpenTelemetry SDK has created and processed telemetry, it needs to be exported.
+This package contains exporters for this purpose.
+

-# OpenTelemetry-Go Jaeger Exporter
-
-[![Go Reference](https://pkg.go.dev/badge/go.opentelemetry.io/otel/exporters/jaeger.svg)](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/jaeger)
-
-[OpenTelemetry span exporter for Jaeger](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/trace/sdk_exporters/jaeger.md) implementation.
-
-## Installation
-
-```
-go get -u go.opentelemetry.io/otel/exporters/jaeger
-```
-
-## Example
-
-See [../../example/jaeger](../../example/jaeger).
-
-## Configuration
-
-The exporter can be used to send spans to:
-
-- Jaeger agent using `jaeger.thrift` over compact thrift protocol via
-  [`WithAgentEndpoint`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/jaeger#WithAgentEndpoint) option.
-- Jaeger collector using `jaeger.thrift` over HTTP via
-  [`WithCollectorEndpoint`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/jaeger#WithCollectorEndpoint) option.
-
-### Environment Variables
-
-The following environment variables can be used
-(instead of options objects) to override the default configuration.
-
-| Environment variable              | Option                                                                                        | Default value                       |
-| --------------------------------- | --------------------------------------------------------------------------------------------- | ----------------------------------- |
-| `OTEL_EXPORTER_JAEGER_AGENT_HOST` | [`WithAgentHost`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/jaeger#WithAgentHost) | `localhost`                         |
-| `OTEL_EXPORTER_JAEGER_AGENT_PORT` | [`WithAgentPort`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/jaeger#WithAgentPort) | `6831`                              |
-| `OTEL_EXPORTER_JAEGER_ENDPOINT`   | [`WithEndpoint`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/jaeger#WithEndpoint)   | `http://localhost:14268/api/traces` |
-| `OTEL_EXPORTER_JAEGER_USER`       | [`WithUsername`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/jaeger#WithUsername)   |                                     |
-| `OTEL_EXPORTER_JAEGER_PASSWORD`   | [`WithPassword`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/jaeger#WithPassword)   |                                     |
-
-Configuration using options have precedence over the environment variables.
-
-## Contributing
-
-This exporter uses a vendored copy of the Apache Thrift library (v0.14.1) at a custom import path.
-When re-generating Thrift code in the future, please adapt import paths as necessary.

-// A trace is a series of spans (often RPC calls) which form a latency tree.
-//
-// The root span is where trace_id = id and parent_id = Nil. The root span is
-// usually the longest interval in the trace, starting with a SERVER_RECV
-// annotation and ending with a SERVER_SEND.
-//
-// Attributes:
-//  - TraceID
-//  - Name: Span name in lowercase, rpc method for example
-//
-// Conventionally, when the span name isn't known, name = "unknown".
-//  - ID
-//  - ParentID
-//  - Annotations
-//  - BinaryAnnotations
-//  - Debug
-//  - Timestamp: Microseconds from epoch of the creation of this span.
-//
-// This value should be set directly by instrumentation, using the most
-// precise value possible. For example, gettimeofday or syncing nanoTime
-// against a tick of currentTimeMillis.
-//
-// For compatibility with instrumentation that precede this field, collectors
-// or span stores can derive this via Annotation.timestamp.
-// For example, SERVER_RECV.timestamp or CLIENT_SEND.timestamp.
-//
-// This field is optional for compatibility with old data: first-party span
-// stores are expected to support this at time of introduction.
-//  - Duration: Measurement of duration in microseconds, used to support queries.
-//
-// This value should be set directly, where possible. Doing so encourages
-// precise measurement decoupled from problems of clocks, such as skew or NTP
-// updates causing time to move backwards.
-//
-// For compatibility with instrumentation that precede this field, collectors
-// or span stores can derive this by subtracting Annotation.timestamp.
-// For example, SERVER_SEND.timestamp - SERVER_RECV.timestamp.
-//
-// If this field is persisted as unset, zipkin will continue to work, except
-// duration query support will be implementation-specific. Similarly, setting
-// this field non-atomically is implementation-specific.
-//
-// This field is i64 vs i32 to support spans longer than 35 minutes.
-//  - TraceIDHigh: Optional unique 8-byte additional identifier for a trace. If non zero, this
-// means the trace uses 128 bit traceIds instead of 64 bit.

-      "Object" form shall mean any form resulting from mechanical
-      transformation or translation of a Source form, including but
-      not limited to compiled object code, generated documentation,
-      and conversions to other media types.
-
-      "Work" shall mean the work of authorship, whether in Source or
-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain
-      separable from, or merely link (or bind by name) to the interfaces of,
-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions
-      to that Work or Derivative Works thereof, that is intentionally
-      submitted to Licensor for inclusion in the Work by the copyright owner
-      or by an individual or Legal Entity authorized to submit on behalf of
-      the copyright owner. For the purposes of this definition, "submitted"
-      means any form of electronic, verbal, or written communication sent
-      to the Licensor or its representatives, including but not limited to
-      communication on electronic mailing lists, source code control systems,
-      and issue tracking systems that are managed by, or on behalf of, the
-      Licensor for the purpose of discussing and improving the Work, but
-      excluding communication that is conspicuously marked or otherwise
-      designated in writing by the copyright owner as "Not a Contribution."
-
-      "Contributor" shall mean Licensor and any individual or Legal Entity
-      on behalf of whom a Contribution has been received by Licensor and
-      subsequently incorporated within the Work.
-
-   2. Grant of Copyright License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-
-   END OF TERMS AND CONDITIONS
-
-   APPENDIX: How to apply the Apache License to your work.

+/*
+Package otlpmetricgrpc provides an OTLP metrics exporter using gRPC.
+By default the telemetry is sent to https://localhost:4317.
+
+Exporter should be created using [New] and used with a [metric.PeriodicReader].
+
+The environment variables described below can be used for configuration.
+
+OTEL_EXPORTER_OTLP_ENDPOINT, OTEL_EXPORTER_OTLP_METRICS_ENDPOINT (default: "https://localhost:4317") -
+target to which the exporter sends telemetry.
+The target syntax is defined in https://github.com/grpc/grpc/blob/master/doc/naming.md.
+The value must contain a host.
+The value may additionally a port, a scheme, and a path.
+The value accepts "http" and "https" scheme.
+The value should not contain a query string or fragment.
+OTEL_EXPORTER_OTLP_METRICS_ENDPOINT takes precedence over OTEL_EXPORTER_OTLP_ENDPOINT.
+The configuration can be overridden by [WithEndpoint], [WithEndpointURL], [WithInsecure], and [WithGRPCConn] options.
+
+OTEL_EXPORTER_OTLP_INSECURE, OTEL_EXPORTER_OTLP_METRICS_INSECURE (default: "false") -
+setting "true" disables client transport security for the exporter's gRPC connection.
+You can use this only when an endpoint is provided without the http or https scheme.
+OTEL_EXPORTER_OTLP_ENDPOINT, OTEL_EXPORTER_OTLP_METRICS_ENDPOINT setting overrides
+the scheme defined via OTEL_EXPORTER_OTLP_ENDPOINT, OTEL_EXPORTER_OTLP_METRICS_ENDPOINT.
+OTEL_EXPORTER_OTLP_METRICS_INSECURE takes precedence over OTEL_EXPORTER_OTLP_INSECURE.
+The configuration can be overridden by [WithInsecure], [WithGRPCConn] options.
+
+OTEL_EXPORTER_OTLP_HEADERS, OTEL_EXPORTER_OTLP_METRICS_HEADERS (default: none) -
+key-value pairs used as gRPC metadata associated with gRPC requests.
+The value is expected to be represented in a format matching to the [W3C Baggage HTTP Header Content Format],
+except that additional semi-colon delimited metadata is not supported.
+Example value: "key1=value1,key2=value2".
+OTEL_EXPORTER_OTLP_METRICS_HEADERS takes precedence over OTEL_EXPORTER_OTLP_HEADERS.
+The configuration can be overridden by [WithHeaders] option.
+
+OTEL_EXPORTER_OTLP_TIMEOUT, OTEL_EXPORTER_OTLP_METRICS_TIMEOUT (default: "10000") -
+maximum time in milliseconds the OTLP exporter waits for each batch export.
+OTEL_EXPORTER_OTLP_METRICS_TIMEOUT takes precedence over OTEL_EXPORTER_OTLP_TIMEOUT.
+The configuration can be overridden by [WithTimeout] option.
+
+OTEL_EXPORTER_OTLP_COMPRESSION, OTEL_EXPORTER_OTLP_METRICS_COMPRESSION (default: none) -
+the gRPC compressor the exporter uses.
+Supported value: "gzip".
+OTEL_EXPORTER_OTLP_METRICS_COMPRESSION takes precedence over OTEL_EXPORTER_OTLP_COMPRESSION.
+The configuration can be overridden by [WithCompressor], [WithGRPCConn] options.
+
+OTEL_EXPORTER_OTLP_CERTIFICATE, OTEL_EXPORTER_OTLP_METRICS_CERTIFICATE (default: none) -
+the filepath to the trusted certificate to use when verifying a server's TLS credentials.
+OTEL_EXPORTER_OTLP_METRICS_CERTIFICATE takes precedence over OTEL_EXPORTER_OTLP_CERTIFICATE.
+The configuration can be overridden by [WithTLSCredentials], [WithGRPCConn] options.
+
+OTEL_EXPORTER_OTLP_CLIENT_CERTIFICATE, OTEL_EXPORTER_OTLP_METRICS_CLIENT_CERTIFICATE (default: none) -
+the filepath to the client certificate/chain trust for clients private key to use in mTLS communication in PEM format.
+OTEL_EXPORTER_OTLP_METRICS_CLIENT_CERTIFICATE takes precedence over OTEL_EXPORTER_OTLP_CLIENT_CERTIFICATE.
+The configuration can be overridden by [WithTLSCredentials], [WithGRPCConn] options.
+
+OTEL_EXPORTER_OTLP_CLIENT_KEY, OTEL_EXPORTER_OTLP_METRICS_CLIENT_KEY (default: none) -
+the filepath  to the clients private key to use in mTLS communication in PEM format.
+OTEL_EXPORTER_OTLP_METRICS_CLIENT_KEY takes precedence over OTEL_EXPORTER_OTLP_CLIENT_KEY.
+The configuration can be overridden by [WithTLSCredentials], [WithGRPCConn] option.
+
+OTEL_EXPORTER_OTLP_METRICS_TEMPORALITY_PREFERENCE (default: "cumulative") -
+aggregation temporality to use on the basis of instrument kind. Supported values:
+  - "cumulative" - Cumulative aggregation temporality for all instrument kinds,
+  - "delta" - Delta aggregation temporality for Counter, Asynchronous Counter and Histogram instrument kinds;
+    Cumulative aggregation for UpDownCounter and Asynchronous UpDownCounter instrument kinds,
+  - "lowmemory" - Delta aggregation temporality for Synchronous Counter and Histogram instrument kinds;
+    Cumulative aggregation temporality for Synchronous UpDownCounter, Asynchronous Counter, and Asynchronous UpDownCounter instrument kinds.
+
+The configuration can be overridden by [WithTemporalitySelector] option.
+
+OTEL_EXPORTER_OTLP_METRICS_DEFAULT_HISTOGRAM_AGGREGATION (default: "explicit_bucket_histogram") -
+default aggregation to use for histogram instruments. Supported values:
+  - "explicit_bucket_histogram" - [Explicit Bucket Histogram Aggregation],
+  - "base2_exponential_bucket_histogram" - [Base2 Exponential Bucket Histogram Aggregation].
+
+The configuration can be overridden by [WithAggregationSelector] option.

-Package otlpmetrichttp provides a client that sends metrics to the collector
-using HTTP with binary protobuf payloads.
+Package otlpmetrichttp provides an OTLP metrics exporter using HTTP with protobuf payloads.
+By default the telemetry is sent to https://localhost:4318/v1/metrics.
 
-This package is currently in a pre-GA phase. Backwards incompatible changes
-may be introduced in subsequent minor version releases as we work to track the
-evolving OpenTelemetry specification and user feedback.

-# OpenTelemetry-Go OTLP Span Exporter
-
-[![Go Reference](https://pkg.go.dev/badge/go.opentelemetry.io/otel/exporters/otlp/otlptrace.svg)](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/otlp/otlptrace)
-
-[OpenTelemetry Protocol Exporter](https://github.com/open-telemetry/opentelemetry-specification/blob/v1.5.0/specification/protocol/exporter.md) implementation.
-
-## Installation
-
-```
-go get -u go.opentelemetry.io/otel/exporters/otlp/otlptrace
-```
-
-## Examples
-
-- [Exporter setup and examples](./otlptracehttp/example_test.go)
-- [Full example sending telemetry to a local collector](../../../example/otel-collector)
-
-## [`otlptrace`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/otlp/otlptrace)
-
-The `otlptrace` package provides an exporter implementing the OTel span exporter interface.
-This exporter is configured using a client satisfying the `otlptrace.Client` interface.
-This client handles the transformation of data into wire format and the transmission of that data to the collector.
-
-## [`otlptracegrpc`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc)
-
-The `otlptracegrpc` package implements a client for the span exporter that sends trace telemetry data to the collector using gRPC with protobuf-encoded payloads.
-
-## [`otlptracehttp`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp)
-
-The `otlptracehttp` package implements a client for the span exporter that sends trace telemetry data to the collector using HTTP with protobuf-encoded payloads.
-
-## Configuration
-
-### Environment Variables
-
-The following environment variables can be used (instead of options objects) to
-override the default configuration. For more information about how each of
-these environment variables is interpreted, see [the OpenTelemetry
-specification](https://github.com/open-telemetry/opentelemetry-specification/blob/v1.8.0/specification/protocol/exporter.md).
-
-| Environment variable                                                     | Option                        | Default value                       |
-| ------------------------------------------------------------------------ |------------------------------ | ----------------------------------- |
-| `OTEL_EXPORTER_OTLP_ENDPOINT` `OTEL_EXPORTER_OTLP_TRACES_ENDPOINT`       | `WithEndpoint` `WithInsecure` | `https://localhost:4317`            |
-| `OTEL_EXPORTER_OTLP_CERTIFICATE` `OTEL_EXPORTER_OTLP_TRACES_CERTIFICATE` | `WithTLSClientConfig`         |                                     |
-| `OTEL_EXPORTER_OTLP_HEADERS` `OTEL_EXPORTER_OTLP_TRACES_HEADERS`         | `WithHeaders`                 |                                     |
-| `OTEL_EXPORTER_OTLP_COMPRESSION` `OTEL_EXPORTER_OTLP_TRACES_COMPRESSION` | `WithCompression`             |                                     |
-| `OTEL_EXPORTER_OTLP_TIMEOUT` `OTEL_EXPORTER_OTLP_TRACES_TIMEOUT`         | `WithTimeout`                 | `10s`                               |
-
-Configuration using options have precedence over the environment variables.

+Package otlptracegrpc provides an OTLP span exporter using gRPC.
+By default the telemetry is sent to https://localhost:4317.
+
+Exporter should be created using [New].
+
+The environment variables described below can be used for configuration.
+
+OTEL_EXPORTER_OTLP_ENDPOINT, OTEL_EXPORTER_OTLP_TRACES_ENDPOINT (default: "https://localhost:4317") -
+target to which the exporter sends telemetry.
+The target syntax is defined in https://github.com/grpc/grpc/blob/master/doc/naming.md.
+The value must contain a host.
+The value may additionally a port, a scheme, and a path.
+The value accepts "http" and "https" scheme.
+The value should not contain a query string or fragment.
+OTEL_EXPORTER_OTLP_TRACES_ENDPOINT takes precedence over OTEL_EXPORTER_OTLP_ENDPOINT.
+The configuration can be overridden by [WithEndpoint], [WithEndpointURL], [WithInsecure], and [WithGRPCConn] options.
+
+OTEL_EXPORTER_OTLP_INSECURE, OTEL_EXPORTER_OTLP_TRACES_INSECURE (default: "false") -
+setting "true" disables client transport security for the exporter's gRPC connection.
+You can use this only when an endpoint is provided without the http or https scheme.
+OTEL_EXPORTER_OTLP_ENDPOINT, OTEL_EXPORTER_OTLP_TRACES_ENDPOINT setting overrides
+the scheme defined via OTEL_EXPORTER_OTLP_ENDPOINT, OTEL_EXPORTER_OTLP_TRACES_ENDPOINT.
+OTEL_EXPORTER_OTLP_TRACES_INSECURE takes precedence over OTEL_EXPORTER_OTLP_INSECURE.
+The configuration can be overridden by [WithInsecure], [WithGRPCConn] options.
+
+OTEL_EXPORTER_OTLP_HEADERS, OTEL_EXPORTER_OTLP_TRACES_HEADERS (default: none) -
+key-value pairs used as gRPC metadata associated with gRPC requests.
+The value is expected to be represented in a format matching to the [W3C Baggage HTTP Header Content Format],
+except that additional semi-colon delimited metadata is not supported.
+Example value: "key1=value1,key2=value2".
+OTEL_EXPORTER_OTLP_TRACES_HEADERS takes precedence over OTEL_EXPORTER_OTLP_HEADERS.
+The configuration can be overridden by [WithHeaders] option.
+
+OTEL_EXPORTER_OTLP_TIMEOUT, OTEL_EXPORTER_OTLP_TRACES_TIMEOUT (default: "10000") -
+maximum time in milliseconds the OTLP exporter waits for each batch export.
+OTEL_EXPORTER_OTLP_TRACES_TIMEOUT takes precedence over OTEL_EXPORTER_OTLP_TIMEOUT.
+The configuration can be overridden by [WithTimeout] option.
+
+OTEL_EXPORTER_OTLP_COMPRESSION, OTEL_EXPORTER_OTLP_TRACES_COMPRESSION (default: none) -
+the gRPC compressor the exporter uses.
+Supported value: "gzip".
+OTEL_EXPORTER_OTLP_TRACES_COMPRESSION takes precedence over OTEL_EXPORTER_OTLP_COMPRESSION.
+The configuration can be overridden by [WithCompressor], [WithGRPCConn] options.
+
+OTEL_EXPORTER_OTLP_CERTIFICATE, OTEL_EXPORTER_OTLP_TRACES_CERTIFICATE (default: none) -
+the filepath to the trusted certificate to use when verifying a server's TLS credentials.
+OTEL_EXPORTER_OTLP_TRACES_CERTIFICATE takes precedence over OTEL_EXPORTER_OTLP_CERTIFICATE.
+The configuration can be overridden by [WithTLSCredentials], [WithGRPCConn] options.
+
+OTEL_EXPORTER_OTLP_CLIENT_CERTIFICATE, OTEL_EXPORTER_OTLP_TRACES_CLIENT_CERTIFICATE (default: none) -
+the filepath to the client certificate/chain trust for clients private key to use in mTLS communication in PEM format.
+OTEL_EXPORTER_OTLP_TRACES_CLIENT_CERTIFICATE takes precedence over OTEL_EXPORTER_OTLP_CLIENT_CERTIFICATE.
+The configuration can be overridden by [WithTLSCredentials], [WithGRPCConn] options.
+
+OTEL_EXPORTER_OTLP_CLIENT_KEY, OTEL_EXPORTER_OTLP_TRACES_CLIENT_KEY (default: none) -
+the filepath  to the clients private key to use in mTLS communication in PEM format.
+OTEL_EXPORTER_OTLP_TRACES_CLIENT_KEY takes precedence over OTEL_EXPORTER_OTLP_CLIENT_KEY.
+The configuration can be overridden by [WithTLSCredentials], [WithGRPCConn] option.

-Package otlptracehttp a client that sends traces to the collector using HTTP
-with binary protobuf payloads.
+Package otlptracehttp provides an OTLP span exporter using HTTP with protobuf payloads.
+By default the telemetry is sent to https://localhost:4318/v1/traces.
+
+Exporter should be created using [New].
+
+The environment variables described below can be used for configuration.
+
+OTEL_EXPORTER_OTLP_ENDPOINT (default: "https://localhost:4318") -
+target base URL ("/v1/traces" is appended) to which the exporter sends telemetry.
+The value must contain a scheme ("http" or "https") and host.
+The value may additionally contain a port and a path.
+The value should not contain a query string or fragment.
+The configuration can be overridden by OTEL_EXPORTER_OTLP_TRACES_ENDPOINT
+environment variable and by [WithEndpoint], [WithEndpointURL], [WithInsecure] options.
+
+OTEL_EXPORTER_OTLP_TRACES_ENDPOINT (default: "https://localhost:4318/v1/traces") -
+target URL to which the exporter sends telemetry.
+The value must contain a scheme ("http" or "https") and host.
+The value may additionally contain a port and a path.
+The value should not contain a query string or fragment.
+The configuration can be overridden by [WithEndpoint], [WithEndpointURL], [WitnInsecure], and [WithURLPath] options.
+
+OTEL_EXPORTER_OTLP_HEADERS, OTEL_EXPORTER_OTLP_TRACES_HEADERS (default: none) -
+key-value pairs used as headers associated with HTTP requests.
+The value is expected to be represented in a format matching to the [W3C Baggage HTTP Header Content Format],
+except that additional semi-colon delimited metadata is not supported.
+Example value: "key1=value1,key2=value2".
+OTEL_EXPORTER_OTLP_TRACES_HEADERS takes precedence over OTEL_EXPORTER_OTLP_HEADERS.
+The configuration can be overridden by [WithHeaders] option.
+
+OTEL_EXPORTER_OTLP_TIMEOUT, OTEL_EXPORTER_OTLP_TRACES_TIMEOUT (default: "10000") -
+maximum time in milliseconds the OTLP exporter waits for each batch export.
+OTEL_EXPORTER_OTLP_TRACES_TIMEOUT takes precedence over OTEL_EXPORTER_OTLP_TIMEOUT.
+The configuration can be overridden by [WithTimeout] option.
+
+OTEL_EXPORTER_OTLP_COMPRESSION, OTEL_EXPORTER_OTLP_TRACES_COMPRESSION (default: none) -
+the compression strategy the exporter uses to compress the HTTP body.
+Supported value: "gzip".
+OTEL_EXPORTER_OTLP_TRACES_COMPRESSION takes precedence over OTEL_EXPORTER_OTLP_COMPRESSION.
+The configuration can be overridden by [WithCompression] option.
+
+OTEL_EXPORTER_OTLP_CERTIFICATE, OTEL_EXPORTER_OTLP_TRACES_CERTIFICATE (default: none) -
+the filepath to the trusted certificate to use when verifying a server's TLS credentials.
+OTEL_EXPORTER_OTLP_TRACES_CERTIFICATE takes precedence over OTEL_EXPORTER_OTLP_CERTIFICATE.
+The configuration can be overridden by [WithTLSClientConfig] option.
+
+OTEL_EXPORTER_OTLP_CLIENT_CERTIFICATE, OTEL_EXPORTER_OTLP_TRACES_CLIENT_CERTIFICATE (default: none) -
+the filepath to the client certificate/chain trust for clients private key to use in mTLS communication in PEM format.
+OTEL_EXPORTER_OTLP_TRACES_CLIENT_CERTIFICATE takes precedence over OTEL_EXPORTER_OTLP_CLIENT_CERTIFICATE.
+The configuration can be overridden by [WithTLSClientConfig] option.
+
+OTEL_EXPORTER_OTLP_CLIENT_KEY, OTEL_EXPORTER_OTLP_TRACES_CLIENT_KEY (default: none) -
+the filepath  to the clients private key to use in mTLS communication in PEM format.
+OTEL_EXPORTER_OTLP_TRACES_CLIENT_KEY takes precedence over OTEL_EXPORTER_OTLP_CLIENT_KEY.
+The configuration can be overridden by [WithTLSClientConfig] option.

+This file contains common utilities and objects to validate memory alignment
+of Go types. The primary use of this functionality is intended to ensure
+`struct` fields that need to be 64-bit aligned so they can be passed as
+arguments to 64-bit atomic operations.
+
+The common workflow is to define a slice of `FieldOffset` and pass them to the
+`Aligned8Byte` function from within a `TestMain` function from a package's
+tests. It is important to make this call from the `TestMain` function prior
+to running the rest of the test suit as it can provide useful diagnostics
+about field alignment instead of ambiguous nil pointer dereference and runtime
+panic.
+
+For more information:
+https://github.com/open-telemetry/opentelemetry-go/issues/341

+arguments to 64-bit atomic operations.
+
+The common workflow is to define a slice of `FieldOffset` and pass them to the
+`Aligned8Byte` function from within a `TestMain` function from a package's
+tests. It is important to make this call from the `TestMain` function prior
+to running the rest of the test suit as it can provide useful diagnostics
+about field alignment instead of ambiguous nil pointer dereference and runtime
+panic.

+# Logs Bridge API
+
+## Abstract
+
+`go.opentelemetry.io/otel/log` provides
+[Logs Bridge API](https://opentelemetry.io/docs/specs/otel/logs/bridge-api/).
+
+The initial version of the design and the prototype
+was created in [#4725](https://github.com/open-telemetry/opentelemetry-go/pull/4725).
+
+## Background
+
+The key challenge is to create a performant API compliant with the [specification](https://opentelemetry.io/docs/specs/otel/logs/bridge-api/)
+with an intuitive and user friendly design.
+Performance is seen as one of the most important characteristics of logging libraries in Go.
+
+## Design
+
+This proposed design aims to:
+
+- be specification compliant,
+- be similar to Trace and Metrics API,
+- take advantage of both OpenTelemetry and `slog` experience to achieve acceptable performance.
+
+### Module structure
+
+The API is published as a single `go.opentelemetry.io/otel/log` Go module.
+
+The module name is compliant with
+[Artifact Naming](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/logs/bridge-api.md#artifact-naming)
+and the package structure is the same as for Trace API and Metrics API.
+

+
+The [`LoggerProvider` abstraction](https://opentelemetry.io/docs/specs/otel/logs/bridge-api/#loggerprovider)
+is defined as an interface:
+
+```go
+type LoggerProvider interface {
+	embedded.LoggerProvider
+	Logger(name string, options ...LoggerOption) Logger
+}
+```
+
+The specification may add new operations to `LoggerProvider`.
+The interface may have methods added without a package major version bump.
+This embeds `embedded.LoggerProvider` to help inform an API implementation
+author about this non-standard API evolution.
+This approach is already used in Trace API and Metrics API.
+
+#### LoggerProvider.Logger
+
+The `Logger` method implements the [`Get a Logger` operation](https://opentelemetry.io/docs/specs/otel/logs/bridge-api/#get-a-logger).
+
+The required `name` parameter is accepted as a `string` method argument.
+
+The following options are defined to support optional parameters:
+
+```go
+func WithInstrumentationVersion(version string) LoggerOption
+func WithInstrumentationAttributes(attr ...attribute.KeyValue) LoggerOption
+func WithSchemaURL(schemaURL string) LoggerOption
+```

+- The method should use some default name if the passed name is empty
+  in order to meet the [specification's SDK requirement](https://opentelemetry.io/docs/specs/otel/logs/sdk/#logger-creation)
+  to return a working logger when an invalid name is passed
+  as well as to resemble the behavior of getting tracers and meters.
+
+`Logger` can be extended by adding new `LoggerOption` options
+and adding new exported fields to the `LoggerConfig` struct.

+and in Metrics API for getting meters.

+### Logger
+
+The [`Logger` abstraction](https://opentelemetry.io/docs/specs/otel/logs/bridge-api/#logger)
+is defined as an interface:
+
+```go
+type Logger interface {
+	embedded.Logger
+	Emit(ctx context.Context, record Record)
+}
+```
+
+The specification may add new operations to `Logger`.
+The interface may have methods added without a package major version bump.
+This embeds `embedded.Logger` to help inform an API implementation
+author about this non-standard API evolution.
+This approach is already used in Trace API and Metrics API.
+
+### Logger.Emit
+
+The `Emit` method implements the [`Emit a LogRecord` operation](https://opentelemetry.io/docs/specs/otel/logs/bridge-api/#emit-a-logrecord).
+
+[`Context` associated with the `LogRecord`](https://opentelemetry.io/docs/specs/otel/context/)
+is accepted as a `context.Context` method argument.
+
+Calls to `Emit` are supposed to be on the hot path.
+Therefore, in order to reduce the number of heap allocations,
+the [`LogRecord` abstraction](https://opentelemetry.io/docs/specs/otel/logs/bridge-api/#emit-a-logrecord),
+is defined as a `Record` type:
+
+```go
+type Record struct {
+	timestamp         time.Time
+	observedTimestamp time.Time
+	severity          Severity
+	severityText      string
+	body              Value
+
+	// The fields below are for optimizing the implementation of
+	// attributes.
+	front [5]KeyValue
+	nFront int // The number of attributes in front.
+	back []KeyValue
+}
+```
+
+[`Timestamp`](https://opentelemetry.io/docs/specs/otel/logs/data-model/#field-timestamp)
+is accessed using following methods:
+
+```go
+func (r *Record) Timestamp() time.Time 
+func (r *Record) SetTimestamp(t time.Time) 
+```
+
+[`ObservedTimestamp`](https://opentelemetry.io/docs/specs/otel/logs/data-model/#field-observedtimestamp)
+is accessed using following methods:
+
+```go
+func (r *Record) ObservedTimestamp() time.Time 
+func (r *Record) SetObservedTimestamp(t time.Time) 
+```
+
+[`SeverityNumber`](https://opentelemetry.io/docs/specs/otel/logs/data-model/#field-severitynumber)
+is accessed using following methods:
+
+```go
+func (r *Record) Severity() Severity
+func (r *Record) SetSeverity(s Severity)
+```
+
+`Severity` type is defined and constants are based on
+[Displaying Severity recommendation](https://opentelemetry.io/docs/specs/otel/logs/data-model/#displaying-severity).
+Additionally, `Severity[Level]1` constants are defined to make the API more readable and user friendly.
+
+```go
+type Severity int
+
+const (
+	SeverityTrace1 Severity = 1 // TRACE
+	SeverityTrace2 Severity = 2 // TRACE2
+	SeverityTrace3 Severity = 3 // TRACE3
+	SeverityTrace4 Severity = 4 // TRACE4
+
+	SeverityDebug1 Severity = 5 // DEBUG
+	SeverityDebug2 Severity = 6 // DEBUG2
+	SeverityDebug3 Severity = 7 // DEBUG3
+	SeverityDebug4 Severity = 8 // DEBUG4
+
+	SeverityInfo1 Severity = 9  // INFO
+	SeverityInfo2 Severity = 10 // INFO2
+	SeverityInfo3 Severity = 11 // INFO3
+	SeverityInfo4 Severity = 12 // INFO4
+
+	SeverityWarn1 Severity = 13 // WARN
+	SeverityWarn2 Severity = 14 // WARN2
+	SeverityWarn3 Severity = 15 // WARN3
+	SeverityWarn4 Severity = 16 // WARN4
+
+	SeverityError1 Severity = 17 // ERROR
+	SeverityError2 Severity = 18 // ERROR2
+	SeverityError3 Severity = 19 // ERROR3

+
+	SeverityFatal1 Severity = 21 // FATAL
+	SeverityFatal2 Severity = 22 // FATAL2
+	SeverityFatal3 Severity = 23 // FATAL3
+	SeverityFatal4 Severity = 24 // FATAL4
+
+	SeverityTrace = SeverityTrace1
+	SeverityDebug = SeverityDebug1
+	SeverityInfo  = SeverityInfo1
+	SeverityWarn  = SeverityWarn1
+	SeverityError = SeverityError1
+	SeverityFatal = SeverityFatal1
+)
+```
+
+[`SeverityText`](https://opentelemetry.io/docs/specs/otel/logs/data-model/#field-severitytext)
+is accessed using following methods:
+
+```go
+func (r *Record) SeverityText() string
+func (r *Record) SetSeverityText(s string)
+```
+
+[`Body`](https://opentelemetry.io/docs/specs/otel/logs/data-model/#field-body)
+is accessed using following methods:
+
+```go
+func (r *Record) Body() Value
+func (r *Record) SetBody(v Value)
+```
+
+[Log record attributes](https://opentelemetry.io/docs/specs/otel/logs/data-model/#field-attributes)
+are accessed using following methods:
+
+```go
+func (r *Record) WalkAttributes(f func(KeyValue) bool)
+func (r *Record) AddAttributes(attrs ...KeyValue)
+```
+
+`Record` has a `AttributesLen` method that returns
+the number of attributes to allow slice preallocation
+when converting records to a different representation:
+
+```go
+func (r *Record) AttributesLen() int
+```
+
+The records attributes design and implementation is based on
+[`slog.Record`](https://pkg.go.dev/log/slog#Record).
+It allows achieving high-performance access and manipulation of the attributes
+while keeping the API user friendly.
+It relieves the user from making his own improvements
+for reducing the number of allocations when passing attributes.
+
+The following definitions are implementing the abstractions
+described in [the specification](https://opentelemetry.io/docs/specs/otel/logs/#new-first-party-application-logs):
+
+```go
+type Value struct{}
+
+type Kind int
+
+const (
+	KindEmpty Kind = iota
+	KindBool
+	KindFloat64
+	KindInt64
+	KindString
+	KindBytes
+	KindSlice
+	KindMap
+)
+
+func (v Value) Kind() Kind
+
+// Value factories:

+func IntValue(v int) Value
+
+func Int64Value(v int64) Value
+

+
+func (v Value) AsInt64() int64
+
+func (v Value) AsBool() bool
+
+func (v Value) AsFloat64() float64
+
+func (v Value) AsBytes() []byte
+
+func (v Value) AsSlice() []Value
+
+func (v Value) AsMap() []KeyValue 
+
+func (v Value) Empty() bool
+
+// Value equality comparison:
+
+func (v Value) Equal(w Value) bool
+
+
+type KeyValue struct {
+	Key   string
+	Value Value
+}
+
+// KeyValue factories:
+
+func String(key, value string) KeyValue
+
+func Int64(key string, value int64) KeyValue
+
+func Int(key string, value int) KeyValue
+
+func Float64(key string, v float64) KeyValue
+
+func Bool(key string, v bool) KeyValue
+
+func Bytes(key string, v []byte) KeyValue
+
+func Slice(key string, args ...Value) KeyValue
+
+func Map(key string, args ...KeyValue) KeyValue
+
+// KeyValue equality comparison:
+
+func (a KeyValue) Equal(b KeyValue) bool
+```
+
+`Value` is representing `any`.
+`KeyValue` is representing a key(string)-value(`any`) pair.
+
+`Kind` is an enumeration used for specifying the underlying value type.
+`KindEmpty` is used for an empty (zero) value.
+`KindBool` is used for boolean value.
+`KindFloat64` is used for a double precision floating point (IEEE 754-1985) value.
+`KindInt64` is used for a signed integer value.
+`KindString` is used for a string value.
+`KindBytes` is used for a slice of bytes (in spec: A byte array).
+`KindSlice` is used for a slice of values (in spec: an array (a list) of any values).
+`KindMap` is used for a slice of key-value pairs (in spec: `map<string, any>`).
+
+These types are defined in `go.opentelemetry.io/otel/log` package
+as their are tightly coupled with the API and different from common attributes.
+
+The internal implementation of `Value` is based on
+[`slog.Value`](https://pkg.go.dev/log/slog#Value)
+and the API is mostly inspired by
+[`attribute.Value`](https://pkg.go.dev/go.opentelemetry.io/otel/attribute#Value).
+The benchmarks[^1] show that the implementation is more performant than
+[`attribute.Value`](https://pkg.go.dev/go.opentelemetry.io/otel/attribute#Value).
+
+The value accessors (`func (v Value) As[Kind]` methods) must not panic,
+as it would violate the [specification](https://opentelemetry.io/docs/specs/otel/error-handling/):
+
+> API methods MUST NOT throw unhandled exceptions when used incorrectly by end
+> users. The API and SDK SHOULD provide safe defaults for missing or invalid
+> arguments. [...] Whenever the library suppresses an error that would otherwise
+> have been exposed to the user, the library SHOULD log the error using
+> language-specific conventions.
+
+Therefore, the value accessors should return a zero value
+and log an error when a bad accessor is called.
+
+The `Severity`, `Kind`, `Value`, `KeyValue` may implement
+the [`fmt.Stringer`](https://pkg.go.dev/fmt#Stringer) interface.
+However, it is not needed for the first stable release
+and the `String` methods can be added later.
+
+The caller must not subsequently mutate the record passed to `Emit`.
+This would allow the implementation to not clone the record,
+but simply retain, modify or discard it.
+The implementation may still choose to clone the record or copy its attributes
+if it needs to retain or modify it,
+e.g. in case of asynchronous processing to eliminate the possibility of data races,
+because the user can technically reuse the record and add new attributes
+after the call (even when the documentation says that the caller must not do it).
+
+Implementation requirements:
+
+- The [specification requires](https://opentelemetry.io/docs/specs/otel/logs/bridge-api/#concurrency-requirements)
+  the method to be safe to be called concurrently.
+
+- The method must not interrupt the record processing if the context is canceled
+  per ["ignoring context cancellation" guideline](../CONTRIBUTING.md#ignoring-context-cancellation).
+
+- The [specification requires](https://opentelemetry.io/docs/specs/otel/logs/bridge-api/#emit-a-logrecord)
+  use the current time as observed timestamp if the passed is empty.
+
+- The method should handle the trace context passed via `ctx` argument in order to meet the
+  [specification's SDK requirement](https://opentelemetry.io/docs/specs/otel/logs/sdk/#readablelogrecord)
+  to populate the trace context fields from the resolved context.
+
+`Emit` can be extended by adding new exported fields to the `Record` struct.

+### noop package
+
+The `go.opentelemetry.io/otel/log/noop` package provides
+[Logs Bridge API No-Op Implementation](https://opentelemetry.io/docs/specs/otel/logs/noop/).
+
+### Trace context correlation
+
+The bridge implementation should do its best to pass
+the `ctx` containing the trace context from the caller
+so it can later be passed via `Logger.Emit`.
+
+It is not expected that users (caller or bridge implementation) reconstruct
+a `context.Context`. Reconstructing a `context.Context` with
+[`trace.ContextWithSpanContext`](https://pkg.go.dev/go.opentelemetry.io/otel/trace#ContextWithSpanContext)
+and [`trace.NewSpanContext`](https://pkg.go.dev/go.opentelemetry.io/otel/trace#NewSpanContext)
+would usually involve more memory allocations.
+
+The logging libraries which have recording methods that accepts `context.Context`,
+such us [`slog`](https://pkg.go.dev/log/slog),
+[`logrus`](https://pkg.go.dev/github.com/sirupsen/logrus),
+[`zerolog`](https://pkg.go.dev/github.com/rs/zerolog),
+makes passing the trace context trivial.
+
+However, some libraries do not accept a `context.Context` in their recording methods.
+Structured logging libraries,
+such as [`logr`](https://pkg.go.dev/github.com/go-logr/logr)
+and [`zap`](https://pkg.go.dev/go.uber.org/zap),
+offer passing `any` type as a log attribute/field.
+Therefore, their bridge implementations can define a "special" log attributes/field
+that will be used to capture the trace context.
+
+[The prototype](https://github.com/open-telemetry/opentelemetry-go/pull/4725)
+has bridge implementations that handle trace context correlation efficiently.
+
+## Benchmarking
+
+The benchmarks take inspiration from [`slog`](https://pkg.go.dev/log/slog),
+because for the Go team it was also critical to create API that would be fast
+and interoperable with existing logging packages.[^2][^3]
+
+The benchmark results can be found in [the prototype](https://github.com/open-telemetry/opentelemetry-go/pull/4725).
+
+## Rejected alternatives
+
+### Reuse slog
+
+The API must not be coupled to [`slog`](https://pkg.go.dev/log/slog),
+nor any other logging library.
+
+The API needs to evolve orthogonally to `slog`.
+
+`slog` is not compliant with the [Logs Bridge API](https://opentelemetry.io/docs/specs/otel/logs/bridge-api/).
+and we cannot expect the Go team to make `slog` compliant with it.
+
+The interoperabilty can be achieved using [a log bridge](https://opentelemetry.io/docs/specs/otel/glossary/#log-appender--bridge).
+
+You can read more about OpenTelemetry Logs design on [opentelemetry.io](https://opentelemetry.io/docs/concepts/signals/logs/).
+
+### Record as interface
+
+`Record` is defined as a `struct` because of the following reasons.
+
+Log record is a value object without any behavior.
+It is used as data input for Logger methods.
+
+The log record resembles the instrument config structs like [metric.Float64CounterConfig](https://pkg.go.dev/go.opentelemetry.io/otel/metric#Float64CounterConfig).
+
+Using `struct` instead of `interface` improves the performance as e.g.
+indirect calls are less optimized,
+usage of interfaces tend to increase heap allocations.[^3]
+
+### Options as parameter to Logger.Emit
+
+One of the initial ideas was to have:
+
+```go
+type Logger interface{
+	embedded.Logger
+	Emit(ctx context.Context, options ...RecordOption)
+}
+```
+
+The main reason was that design would be similar
+to the [Meter API](https://pkg.go.dev/go.opentelemetry.io/otel/metric#Meter)
+for creating instruments.
+
+However, passing `Record` directly, instead of using options,
+is more performant as it reduces heap allocations.[^4]
+
+Another advantage of passing `Record` is that API would not have functions like `NewRecord(options...)`,
+which would be used by the SDK and not by the users.
+
+Finally, the definition would be similar to [`slog.Handler.Handle`](https://pkg.go.dev/log/slog#Handler)
+that was designed to provide optimization opportunities.[^2]
+
+### Passing record as pointer to Logger.Emit
+
+So far the benchmarks do not show differences that would
+favor passing the record via pointer (and vice versa).
+
+Passing via value feels safer because of the following reasons.
+
+The user would not be able to pass `nil`.
+Therefore, it reduces the possibility to have a nil pointer dereference.
+
+It should reduce the possibility of a heap allocation.
+
+It follows the design of [`slog.Handler`](https://pkg.go.dev/log/slog#Handler).
+
+If follows one of Google's Go Style Decisions
+to prefer [passing values](https://google.github.io/styleguide/go/decisions#pass-values).
+
+### Passing struct as parameter to LoggerProvider.Logger
+
+Similarly to `Logger.Emit`, we could have something like:
+
+```go
+type LoggerProvider interface{
+	embedded.LoggerProvider
+	Logger(name context.Context, config LoggerConfig)
+}
+```
+
+The drawback of this idea would be that this would be
+a different design from Trace and Metrics API.
+
+The performance of acquiring a logger is not as critical
+as the performance of emitting a log record. While a single
+HTTP/RPC handler could write hundreds of logs, it should not
+create a new logger for each log entry.
+The bridge implementation should reuse loggers whenever possible.
+
+### Logger.WithAttributes
+
+We could add `WithAttributes` to the `Logger` interface.
+Then `Record` could be a simple struct with only exported fields.
+The idea was that the SDK would implement the performance improvements
+instead of doing it in the API.
+This would allow having different optimization strategies.
+
+During the analysis[^5], it occurred that the main problem of this proposal
+is that the variadic slice passed to an interface method is always heap allocated.
+
+Moreover, the logger returned by `WithAttribute` was allocated on the heap.
+
+Lastly, the proposal was not specification compliant.
+
+### Record attributes as slice
+
+One of the proposals[^6] was to have `Record` as a simple struct:
+
+```go
+type Record struct {
+	Timestamp         time.Time
+	ObservedTimestamp time.Time
+	Severity          Severity
+	SeverityText      string
+	Body              Value
+	Attributes        []KeyValue
+```
+
+The bridge implementations could use [`sync.Pool`](https://pkg.go.dev/sync#Pool)
+for reducing the number of allocations when passing attributes.
+
+The benchmarks results were better.
+
+In such a design, most bridges would have a `sync.Pool`
+to reduce the number of heap allocations.
+However, the `sync.Pool` will not work correctly with API implementations
+that would take ownership of the record
+(e.g. implementations that do not copy records for asynchronous processing).
+The current design, even in case of improper API implementation,
+has lower  chances of encountering a bug as most bridges would
+create a record, pass it, and forget about it.
+
+For reference, here is the reason why `slog` does not use `sync.Pool`[^3]
+as well:
+
+> We can use a sync pool for records though we decided not to.
+You can but it's a bad idea for us. Why?
+Because users have control of Records.
+Handler writers can get their hands on a record
+and we'd have to ask them to free it
+or try to free it magically at some some point.
+But either way, they could get themselves in trouble by freeing it twice
+or holding on to one after they free it.
+That's a use after free bug and that's why `zerolog` was problematic for us.
+`zerolog` as as part of its speed exposes a pool allocated value to users
+if you use `zerolog` the normal way, that you'll see in all the examples,
+you will never encounter a problem.
+But if you do something a little out of the ordinary you can get
+use after free bugs and we just didn't want to put that in the standard library.
+
+Therefore, we decided to not follow the proposal as it is
+less user friendly (users and bridges would use e.g. a `sync.Pool` to reduce
+the number of heap allocation), less safe (more prone to use after free bugs
+and race conditions), and the benchmark differences were not significant.
+
+### Use any instead of defining Value
+
+[Logs Data Model](https://opentelemetry.io/docs/specs/otel/logs/data-model/#field-body)
+defines Body to be `any`.
+One could propose to define `Body` (and attribute values) as `any`
+instead of a defining a new type (`Value`).
+
+First of all, [`any` type defined in the specification](https://opentelemetry.io/docs/specs/otel/logs/data-model/#type-any)
+is not the same as `any` (`interface{}`) in Go.
+
+Moreover, using `any` as a field would decrease the performance.[^7]
+
+Notice it will be still possible to add following kind and factories
+in a backwards compatible way:
+
+```go
+const KindMap Kind
+
+func AnyValue(value any) KeyValue
+
+func Any(key string, value any) KeyValue
+```
+
+However, currently, it would not be specification compliant.
+
+### Severity type encapsulating number and text
+
+We could combine severity into a single field defining a type:
+
+```go
+type Severity struct {
+	Number SeverityNumber
+	Text string
+}
+```
+
+However, the [Logs Data Model](https://opentelemetry.io/docs/specs/otel/logs/data-model/#log-and-event-record-definition)
+define it as independent fields.
+It should be more user friendly to have them separated.
+Especially when having getter and setter methods, setting one value
+when the other is already set would be unpleasant.
+
+## Reuse attribute package
+
+It was tempting to reuse the existing
+[https://pkg.go.dev/go.opentelemetry.io/otel/attribute] package
+for defining log attributes and body.
+
+However, this would be wrong because [the log attribute definition](https://opentelemetry.io/docs/specs/otel/logs/data-model/#field-attributes)
+is different from [the common attribute definition](https://opentelemetry.io/docs/specs/otel/common/#attribute).
+
+Moreover, it there is nothing telling that [the body definition](https://opentelemetry.io/docs/specs/otel/logs/data-model/#field-body)
+has anything in common with a common attribute value.
+
+Therefore, we define new types representing the abstract types defined
+in the [Logs Data Model](https://opentelemetry.io/docs/specs/otel/logs/data-model/#definitions-used-in-this-document).
+
+## Mix receiver types for Record
+
+Methods of [`slog.Record`](https://pkg.go.dev/log/slog#Record)
+have different receiver types.
+
+In `log/slog` GitHub issue we can only find that the reason is:[^8]
+
+>> some receiver of Record struct is by value
+> Passing Records by value means they incur no heap allocation.
+> That improves performance overall, even though they are copied.
+
+However, the benchmarks do not show any noticeable differences.[^9]
+
+The compiler is smart-enough to not make a heap allocation for any of these methods.
+The use of a pointer receiver does not cause any heap allocation.
+From Go FAQ:[^10]
+
+> In the current compilers, if a variable has its address taken,
+> that variable is a candidate for allocation on the heap.
+> However, a basic escape analysis recognizes some cases
+> when such variables will not live past the return from the function
+> and can reside on the stack.
+
+The [Understanding Allocations: the Stack and the Heap](https://www.youtube.com/watch?v=ZMZpH4yT7M0)
+presentation by Jacob Walker describes the escape analysis with details.
+
+Moreover, also from Go FAQ:[^10]
+
+> Also, if a local variable is very large,
+> it might make more sense to store it on the heap rather than the stack.
+
+Therefore, even if we use a value receiver and the value is very large
+it may be heap allocated.
+
+Both [Go Code Review Comments](https://go.dev/wiki/CodeReviewComments#receiver-type)
+and [Google's Go Style Decisions](https://google.github.io/styleguide/go/decisions#receiver-type)
+highly recommend making the methods for a type either all pointer methods
+or all value methods. Google's Go Style Decisions even goes further and says:
+
+> There is a lot of misinformation about whether passing a value or a pointer
+> to a function can affect performance.
+> The compiler can choose to pass pointers to values on the stack
+> as well as copying values on the stack,
+> but these considerations should not outweigh the readability
+> and correctness of the code in most circumstances.
+> When the performance does matter, it is important to profile both approaches
+> with a realistic benchmark before deciding that one approach outperforms the other.
+
+Because, the benchmarks[^9] do not proof any performance difference
+and the general recommendation is to not mix receiver types,
+we decided to use pointer receivers for all `Record` methods.
+
+### Add XYZ method to Logger
+
+The `Logger` does not have methods like `Enabled`, `SetSeverity`, etc.
+as the Bridge API needs to follow (be compliant with)
+the [specification](https://opentelemetry.io/docs/specs/otel/logs/bridge-api/)
+
+Moreover, the Bridge API is intendend to be used to implement bridges.
+Applications should not use it directly. The applications should use logging packages
+such as [`slog`](https://pkg.go.dev/log/slog),
+[`logrus`](https://pkg.go.dev/github.com/sirupsen/logrus),
+[`zap`](https://pkg.go.dev/go.uber.org/zap),
+[`zerolog`](https://pkg.go.dev/github.com/rs/zerolog),
+[`logr`](https://pkg.go.dev/github.com/go-logr/logr).
+
+### Rename KeyValue to Attr
+
+There was a proposal to rename `KeyValue` to `Attr` (or `Attribute`).[^11]
+New developers may not intuitively know that `log.KeyValue` is an attribute in
+the OpenTelemetry parlance.
+
+During the discussion we agreed to keep the `KeyValue` name.
+
+The type is used in two semantics:
+
+- as a log attribute
+- as a map item
+
+As for map item semantics, this type is a key-value pair, not an attribute.
+Naming the type as `Attr` would convey semantical meaning
+that would not be correct for a map.
+
+We expect that most of the Bridge API users will be OpenTelemetry contributors.
+We plan to implement bridges for the most popular logging libraries ourselves.
+Given we will all have the context needed to disambiguate these overlapping
+names, developers' confusion should not be an issue.
+
+For bridges not developed by us,
+developers will likely look at our existing bridges for inspiration.
+Our correct use of these types will be a reference to them.
+
+At last, we could consider a design defining both types: `KeyValue` and `Attr`.
+However, in this approach we would need have factory functions for both types.
+It would make the API surface unnecessarily big,
+and we may even have problems naming the functions.
+
+## Open issues
+
+The Logs Bridge API MUST NOT be released as stable
+before all issues below are closed:
+
+- [Clarify that log attributes are NOT common attributes](https://github.com/open-telemetry/opentelemetry-specification/issues/3849)
+- [Clarify handling empty (null) values in Logs Data Model](https://github.com/open-telemetry/opentelemetry-specification/issues/3835)
+- [Clarify attributes parameter type of Get a Logger operation](https://github.com/open-telemetry/opentelemetry-specification/issues/3841)

+/*
+Package log provides the OpenTelemetry Logs Bridge API.
+
+This package is intended to be a bridge between existing logging libraries and
+OpenTelemetry. It is not designed to be a logging API itself.
+
+# API Implementations
+
+This package does not conform to the standard Go versioning policy, all of its
+interfaces may have methods added to them without a package major version bump.
+This non-standard API evolution could surprise an uninformed implementation
+author. They could unknowingly build their implementation in a way that would
+result in a runtime panic for their users that update to the new API.
+
+The API is designed to help inform an instrumentation author about this
+non-standard API evolution. It requires them to choose a default behavior for
+unimplemented interface methods. There are three behavior choices they can
+make:
+
+  - Compilation failure
+  - Panic
+  - Default to another implementation
+
+All interfaces in this API embed a corresponding interface from
+go.opentelemetry.io/otel/log/embedded. If an author wants the default behavior
+of their implementations to be a compilation failure, signaling to their users
+they need to update to the latest version of that implementation, they need to
+embed the corresponding interface from go.opentelemetry.io/otel/log/embedded in
+their implementation. For example,
+
+	import "go.opentelemetry.io/otel/log/embedded"
+
+	type LoggerProvider struct {
+		embedded.LoggerProvider
+		// ...
+	}
+
+If an author wants the default behavior of their implementations to a panic,
+they need to embed the API interface directly.
+
+	import "go.opentelemetry.io/otel/log"
+
+	type LoggerProvider struct {
+		log.LoggerProvider
+		// ...
+	}
+
+This is not a recommended behavior as it could lead to publishing packages that
+contain runtime panics when users update other package that use newer versions
+of go.opentelemetry.io/otel/log.
+
+Finally, an author can embed another implementation in theirs. The embedded
+implementation will be used for methods not defined by the author. For example,
+an author who wants to default to silently dropping the call can use
+o.opentelemetry.io/otel/log/noop:
+
+	import "go.opentelemetry.io/otel/log/noop"
+
+	type LoggerProvider struct {
+		noop.LoggerProvider
+		// ...
+	}
+
+It is strongly recommended that authors only embed
+go.opentelemetry.io/otel/log/noop if they choose this default behavior. That
+implementation is the only one OpenTelemetry authors can guarantee will fully
+implement all the API interfaces when a user updates their API.

 /*
-Package metric provides an implementation of the metrics part of the
-OpenTelemetry API.
+Package metric provides the OpenTelemetry API used to measure metrics about
+source code operation.
 
-This package is currently in a pre-GA phase. Backwards incompatible changes
-may be introduced in subsequent minor version releases as we work to track the
-evolving OpenTelemetry specification and user feedback.
+This API is separate from its implementation so the instrumentation built from
+it is reusable. See [go.opentelemetry.io/otel/sdk/metric] for the official
+OpenTelemetry implementation of this API.
 
-Measurements can be made about an operation being performed or the state of a
-system in general. These measurements can be crucial to the reliable operation
-of code and provide valuable insights about the inner workings of a system.
+All measurements made with this package are made via instruments. These
+instruments are created by a [Meter] which itself is created by a
+[MeterProvider]. Applications need to accept a [MeterProvider] implementation
+as a starting point when instrumenting. This can be done directly, or by using
+the OpenTelemetry global MeterProvider via [GetMeterProvider]. Using an
+appropriately named [Meter] from the accepted [MeterProvider], instrumentation
+can then be built from the [Meter]'s instruments.
 
-Measurements are made using instruments provided by this package. The type of
-instrument used will depend on the type of measurement being made and of what
-part of a system is being measured.
+# Instruments
 
-Instruments are categorized as Synchronous or Asynchronous and independently
-as Adding or Grouping. Synchronous instruments are called by the user with a
-Context. Asynchronous instruments are called by the SDK during collection.
-Adding instruments are semantically intended for capturing a sum. Grouping
-instruments are intended for capturing a distribution.
+Each instrument is designed to make measurements of a particular type. Broadly,
+all instruments fall into two overlapping logical categories: asynchronous or
+synchronous, and int64 or float64.
 
-Adding instruments may be monotonic, in which case they are non-decreasing
-and naturally define a rate.
+All synchronous instruments ([Int64Counter], [Int64UpDownCounter],
+[Int64Histogram], [Float64Counter], [Float64UpDownCounter], and
+[Float64Histogram]) are used to measure the operation and performance of source
+code during the source code execution. These instruments only make measurements
+when the source code they instrument is run.
 
-The synchronous instrument names are:
+All asynchronous instruments ([Int64ObservableCounter],
+[Int64ObservableUpDownCounter], [Int64ObservableGauge],
+[Float64ObservableCounter], [Float64ObservableUpDownCounter], and
+[Float64ObservableGauge]) are used to measure metrics outside of the execution
+of source code. They are said to make "observations" via a callback function
+called once every measurement collection cycle.
 
-  Counter:           adding, monotonic
-  UpDownCounter:     adding
-  Histogram:         grouping
+Each instrument is also grouped by the value type it measures. Either int64 or
+float64. The value being measured will dictate which instrument in these
+categories to use.
 
-and the asynchronous instruments are:
+Outside of these two broad categories, instruments are described by the
+function they are designed to serve. All Counters ([Int64Counter],
+[Float64Counter], [Int64ObservableCounter], and [Float64ObservableCounter]) are
+designed to measure values that never decrease in value, but instead only
+incrementally increase in value. UpDownCounters ([Int64UpDownCounter],
+[Float64UpDownCounter], [Int64ObservableUpDownCounter], and
+[Float64ObservableUpDownCounter]) on the other hand, are designed to measure
+values that can increase and decrease. When more information needs to be
+conveyed about all the synchronous measurements made during a collection cycle,
+a Histogram ([Int64Histogram] and [Float64Histogram]) should be used. Finally,
+when just the most recent measurement needs to be conveyed about an
+asynchronous measurement, a Gauge ([Int64ObservableGauge] and
+[Float64ObservableGauge]) should be used.
 
-  CounterObserver:       adding, monotonic
-  UpDownCounterObserver: adding
-  GaugeObserver:         grouping
+See the [OpenTelemetry documentation] for more information about instruments
+and their intended use.
 
-All instruments are provided with support for either float64 or int64 input
-values.
+# Measurements
 
-An instrument is created using a Meter. Additionally, a Meter is used to
-record batches of synchronous measurements or asynchronous observations. A
-Meter is obtained using a MeterProvider. A Meter, like a Tracer, is unique to
-the instrumentation it instruments and must be named and versioned when
-created with a MeterProvider with the name and version of the instrumentation
-library.
+Measurements are made by recording values and information about the values with
+an instrument. How these measurements are recorded depends on the instrument.
 
-Instrumentation should be designed to accept a MeterProvider from which it can
-create its own unique Meter. Alternatively, the registered global
-MeterProvider from the go.opentelemetry.io/otel package can be used as a
-default.
+Measurements for synchronous instruments ([Int64Counter], [Int64UpDownCounter],
+[Int64Histogram], [Float64Counter], [Float64UpDownCounter], and
+[Float64Histogram]) are recorded using the instrument methods directly. All
+counter instruments have an Add method that is used to measure an increment
+value, and all histogram instruments have a Record method to measure a data
+point.
+
+Asynchronous instruments ([Int64ObservableCounter],
+[Int64ObservableUpDownCounter], [Int64ObservableGauge],
+[Float64ObservableCounter], [Float64ObservableUpDownCounter], and
+[Float64ObservableGauge]) record measurements within a callback function. The
+callback is registered with the Meter which ensures the callback is called once
+per collection cycle. A callback can be registered two ways: during the
+instrument's creation using an option, or later using the RegisterCallback
+method of the [Meter] that created the instrument.
+
+If the following criteria are met, an option ([WithInt64Callback] or
+[WithFloat64Callback]) can be used during the asynchronous instrument's
+creation to register a callback ([Int64Callback] or [Float64Callback],
+respectively):
+
+  - The measurement process is known when the instrument is created
+  - Only that instrument will make a measurement within the callback
+  - The callback never needs to be unregistered
+
+If the criteria are not met, use the RegisterCallback method of the [Meter] that
+created the instrument to register a [Callback].
+
+# API Implementations
+
+This package does not conform to the standard Go versioning policy, all of its
+interfaces may have methods added to them without a package major version bump.
+This non-standard API evolution could surprise an uninformed implementation
+author. They could unknowingly build their implementation in a way that would
+result in a runtime panic for their users that update to the new API.
+
+The API is designed to help inform an instrumentation author about this
+non-standard API evolution. It requires them to choose a default behavior for
+unimplemented interface methods. There are three behavior choices they can
+make:
+
+  - Compilation failure
+  - Panic
+  - Default to another implementation
+
+All interfaces in this API embed a corresponding interface from
+[go.opentelemetry.io/otel/metric/embedded]. If an author wants the default
+behavior of their implementations to be a compilation failure, signaling to
+their users they need to update to the latest version of that implementation,
+they need to embed the corresponding interface from
+[go.opentelemetry.io/otel/metric/embedded] in their implementation. For
+example,
+
+	import "go.opentelemetry.io/otel/metric/embedded"
+
+	type MeterProvider struct {
+		embedded.MeterProvider
+		// ...
+	}
+
+If an author wants the default behavior of their implementations to a panic,
+they need to embed the API interface directly.
+
+	import "go.opentelemetry.io/otel/metric"
+
+	type MeterProvider struct {
+		metric.MeterProvider
+		// ...
+	}
+
+This is not a recommended behavior as it could lead to publishing packages that
+contain runtime panics when users update other package that use newer versions
+of [go.opentelemetry.io/otel/metric].
+
+Finally, an author can embed another implementation in theirs. The embedded
+implementation will be used for methods not defined by the author. For example,
+an author who wants to default to silently dropping the call can use
+[go.opentelemetry.io/otel/metric/noop]:
+
+	import "go.opentelemetry.io/otel/metric/noop"
+
+	type MeterProvider struct {
+		noop.MeterProvider
+		// ...
+	}
+
+It is strongly recommended that authors only embed
+[go.opentelemetry.io/otel/metric/noop] if they choose this default behavior.
+That implementation is the only one OpenTelemetry authors can guarantee will
+fully implement all the API interfaces when a user updates their API.

+This file contains common utilities and objects to validate memory alignment
+of Go types. The primary use of this functionality is intended to ensure
+`struct` fields that need to be 64-bit aligned so they can be passed as
+arguments to 64-bit atomic operations.
+
+The common workflow is to define a slice of `FieldOffset` and pass them to the
+`Aligned8Byte` function from within a `TestMain` function from a package's
+tests. It is important to make this call from the `TestMain` function prior
+to running the rest of the test suit as it can provide useful diagnostics
+about field alignment instead of ambiguous nil pointer dereference and runtime
+panic.
+
+For more information:

-Package metric implements the OpenTelemetry metric API.
-
-This package is currently in a pre-GA phase. Backwards incompatible changes
-may be introduced in subsequent minor version releases as we work to track the
-evolving OpenTelemetry specification and user feedback.
-
-The Accumulator type supports configurable metrics export behavior through a
-collection of export interfaces that support various export strategies,
-described below.
-
-The OpenTelemetry metric API consists of methods for constructing synchronous
-and asynchronous instruments.  There are two constructors per instrument for
-the two kinds of number (int64, float64).
-
-Synchronous instruments are managed by a sync.Map containing a *record
-with the current state for each synchronous instrument.  A lock-free
-algorithm is used to protect against races when adding and removing
-items from the sync.Map.
-
-Asynchronous instruments are managed by an internal
-AsyncInstrumentState, which coordinates calling batch and single
-instrument callbacks.
-
-Internal Structure
-
-Each observer also has its own kind of record stored in the SDK. This
-record contains a set of recorders for every specific label set used in the
-callback.
-
-A sync.Map maintains the mapping of current instruments and label sets to
-internal records.  To find a record, the SDK consults the Map to
-locate an existing record, otherwise it constructs a new record.  The SDK
-maintains a count of the number of references to each record, ensuring
-that records are not reclaimed from the Map while they are still active
-from the user's perspective.
-
-Metric collection is performed via a single-threaded call to Collect that
-sweeps through all records in the SDK, checkpointing their state.  When a
-record is discovered that has no references and has not been updated since
-the prior collection pass, it is removed from the Map.
-
-Both synchronous and asynchronous instruments have an associated
-aggregator, which maintains the current state resulting from all metric
-events since its last checkpoint.  Aggregators may be lock-free or they may
-use locking, but they should expect to be called concurrently.  Aggregators
-must be capable of merging with another aggregator of the same type.
-
-Export Pipeline
-
-While the SDK serves to maintain a current set of records and
-coordinate collection, the behavior of a metrics export pipeline is
-configured through the export types in
-go.opentelemetry.io/otel/sdk/export/metric.  It is important to keep
-in mind the context these interfaces are called from.  There are two
-contexts, instrumentation context, where a user-level goroutine that
-enters the SDK resulting in a new record, and collection context,
-where a system-level thread performs a collection pass through the
-SDK.
-
-Descriptor is a struct that describes the metric instrument to the
-export pipeline, containing the name, units, description, metric kind,
-number kind (int64 or float64).  A Descriptor accompanies metric data
-as it passes through the export pipeline.
-
-The AggregatorSelector interface supports choosing the method of
-aggregation to apply to a particular instrument, by delegating the
-construction of an Aggregator to this interface.  Given the Descriptor,
-the AggregatorFor method returns an implementation of Aggregator.  If this
-interface returns nil, the metric will be disabled.  The aggregator should
-be matched to the capabilities of the exporter.  Selecting the aggregator
-for Adding instruments is relatively straightforward, but many options
-are available for aggregating distributions from Grouping instruments.
-
-Aggregator is an interface which implements a concrete strategy for
-aggregating metric updates.  Several Aggregator implementations are
-provided by the SDK.  Aggregators may be lock-free or use locking,
-depending on their structure and semantics.  Aggregators implement an
-Update method, called in instrumentation context, to receive a single
-metric event.  Aggregators implement a Checkpoint method, called in
-collection context, to save a checkpoint of the current state.
-Aggregators implement a Merge method, also called in collection
-context, that combines state from two aggregators into one.  Each SDK
-record has an associated aggregator.
-
-Processor is an interface which sits between the SDK and an exporter.
-The Processor embeds an AggregatorSelector, used by the SDK to assign
-new Aggregators.  The Processor supports a Process() API for submitting
-checkpointed aggregators to the processor, and a Reader() API
-for producing a complete checkpoint for the exporter.  Two default
-Processor implementations are provided, the "defaultkeys" Processor groups
-aggregate metrics by their recommended Descriptor.Keys(), the
-"simple" Processor aggregates metrics at full dimensionality.
-
-LabelEncoder is an optional optimization that allows an exporter to
-provide the serialization logic for labels.  This allows avoiding
-duplicate serialization of labels, once as a unique key in the SDK (or
-Processor) and once in the exporter.
-
-Reader is an interface between the Processor and the Exporter.
-After completing a collection pass, the Processor.Reader() method
-returns a Reader, which the Exporter uses to iterate over all
-the updated metrics.
-
-Record is a struct containing the state of an individual exported
-metric.  This is the result of one collection interface for one
-instrument and one label set.
-
-Labels is a struct containing an ordered set of labels, the
-corresponding unique encoding, and the encoder that produced it.
-
-Exporter is the final stage of an export pipeline.  It is called with
-a Reader capable of enumerating all the updated metrics.
-
-Controller is not an export interface per se, but it orchestrates the
-export pipeline.  For example, a "push" controller will establish a
-periodic timer to regularly collect and export metrics.  A "pull"
-controller will await a pull request before initiating metric
-collection.  Either way, the job of the controller is to call the SDK
-Collect() method, then read the checkpoint, then invoke the exporter.
-Controllers are expected to implement the public metric.MeterProvider
-API, meaning they can be installed as the global Meter provider.

+// Package metric provides an implementation of the OpenTelemetry metrics SDK.
+//
+// See https://opentelemetry.io/docs/concepts/signals/metrics/ for information
+// about the concept of OpenTelemetry metrics and
+// https://opentelemetry.io/docs/concepts/components/ for more information
+// about OpenTelemetry SDKs.
+//
+// The entry point for the metric package is the MeterProvider. It is the
+// object that all API calls use to create Meters, instruments, and ultimately
+// make metric measurements. Also, it is an object that should be used to
+// control the life-cycle (start, flush, and shutdown) of the SDK.
+//
+// A MeterProvider needs to be configured to export the measured data, this is
+// done by configuring it with a Reader implementation (using the WithReader
+// MeterProviderOption). Readers take two forms: ones that push to an endpoint
+// (NewPeriodicReader), and ones that an endpoint pulls from. See
+// [go.opentelemetry.io/otel/exporters] for exporters that can be used as
+// or with these Readers.
+//
+// Each Reader, when registered with the MeterProvider, can be augmented with a
+// View. Views allow users that run OpenTelemetry instrumented code to modify
+// the generated data of that instrumentation.
+//
+// The data generated by a MeterProvider needs to include information about its
+// origin. A MeterProvider needs to be configured with a Resource, using the
+// WithResource MeterProviderOption, to include this information. This Resource
+// should be used to describe the unique runtime environment instrumented code
+// is being run on. That way when multiple instances of the code are collected
+// at a single endpoint their origin is decipherable.
+//
+// See [go.opentelemetry.io/otel/metric] for more information about
+// the metric API.
+//
+// See [go.opentelemetry.io/otel/sdk/metric/internal/x] for information about
+// the experimental features.

+	//   0) Pre-calculate the random count greater than the storage size when
+	//      an exemplar will be replaced.
+	//   1) Accept all measurements offered until the configured storage size is
+	//      reached.
+	//   2) Loop:
+	//      a) When the pre-calculate count is reached, replace a random
+	//         existing exemplar with the offered measurement.
+	//      b) Calculate the next random count greater than the existing one
+	//         which will replace another exemplars
+	//
+	// The way a "replacement" count is computed is by looking at `n` number of
+	// independent random numbers each corresponding to an offered measurement.
+	// Of these numbers the smallest `k` (the same size as the storage
+	// capacity) of them are kept as a subset. The maximum value in this
+	// subset, called `w` is used to weight another random number generation
+	// for the next count that will be considered.
+	//
+	// By weighting the next count computation like described, it is able to
+	// perform a uniformly-weighted sampling algorithm based on the number of
+	// samples the reservoir has seen so far. The sampling will "slow down" as
+	// more and more samples are offered so as to reduce a bias towards those
+	// offered just prior to the end of the collection.
+	//
+	// This algorithm is preferred because of its balance of simplicity and
+	// performance. It will compute three random numbers (the bulk of
+	// computation time) for each item that becomes part of the reservoir, but
+	// it does not spend any time on items that do not. In particular it has an
+	// asymptotic runtime of O(k(1 + log(n/k)) where n is the number of
+	// measurements offered and k is the reservoir size.
+	//
+	// See https://en.wikipedia.org/wiki/Reservoir_sampling for an overview of
+	// this and other reservoir sampling algorithms. See
+	// https://github.com/MrAlias/reservoir-sampling for a performance
+	// comparison of reservoir sampling algorithms.

+# Experimental Features
+
+The metric SDK contains features that have not yet stabilized in the OpenTelemetry specification.
+These features are added to the OpenTelemetry Go metric SDK prior to stabilization in the specification so that users can start experimenting with them and provide feedback.
+
+These feature may change in backwards incompatible ways as feedback is applied.
+See the [Compatibility and Stability](#compatibility-and-stability) section for more information.
+
+## Features
+
+- [Cardinality Limit](#cardinality-limit)
+- [Exemplars](#exemplars)
+
+### Cardinality Limit
+
+The cardinality limit is the hard limit on the number of metric streams that can be collected for a single instrument.
+
+This experimental feature can be enabled by setting the `OTEL_GO_X_CARDINALITY_LIMIT` environment value.
+The value must be an integer value.
+All other values are ignored.
+
+If the value set is less than or equal to `0`, no limit will be applied.
+
+#### Examples
+
+Set the cardinality limit to 2000.
+
+```console
+export OTEL_GO_X_CARDINALITY_LIMIT=2000
+```
+
+Set an infinite cardinality limit (functionally equivalent to disabling the feature).
+
+```console
+export OTEL_GO_X_CARDINALITY_LIMIT=-1
+```
+
+Disable the cardinality limit.
+
+```console
+unset OTEL_GO_X_CARDINALITY_LIMIT
+```
+
+### Exemplars
+
+A sample of measurements made may be exported directly as a set of exemplars.
+
+This experimental feature can be enabled by setting the `OTEL_GO_X_EXEMPLAR` environment variable.
+The value of must be the case-insensitive string of `"true"` to enable the feature.
+All other values are ignored.
+
+Exemplar filters are a supported.
+The exemplar filter applies to all measurements made.
+They filter these measurements, only allowing certain measurements to be passed to the underlying exemplar reservoir.
+
+To change the exemplar filter from the default `"trace_based"` filter set the `OTEL_METRICS_EXEMPLAR_FILTER` environment variable.
+The value must be the case-sensitive string defined by the [OpenTelemetry specification].
+
+- `"always_on"`: allows all measurements
+- `"always_off"`: denies all measurements
+- `"trace_based"`: allows only sampled measurements
+
+All values other than these will result in the default, `"trace_based"`, exemplar filter being used.
+
+[OpenTelemetry specification]: https://github.com/open-telemetry/opentelemetry-specification/blob/a6ca2fd484c9e76fe1d8e1c79c99f08f4745b5ee/specification/configuration/sdk-environment-variables.md#exemplar
+
+#### Examples
+
+Enable exemplars to be exported.
+
+```console
+export OTEL_GO_X_EXEMPLAR=true
+```
+
+Disable exemplars from being exported.
+
+```console
+unset OTEL_GO_X_EXEMPLAR
+```
+
+Set the exemplar filter to allow all measurements.
+
+```console
+export OTEL_METRICS_EXEMPLAR_FILTER=always_on
+```
+
+Set the exemplar filter to deny all measurements.
+
+```console
+export OTEL_METRICS_EXEMPLAR_FILTER=always_off
+```
+
+Set the exemplar filter to only allow sampled measurements.
+
+```console
+export OTEL_METRICS_EXEMPLAR_FILTER=trace_based
+```
+
+Revert to the default exemplar filter (`"trace_based"`)
+
+```console
+unset OTEL_METRICS_EXEMPLAR_FILTER
+```
+
+## Compatibility and Stability
+
+Experimental features do not fall within the scope of the OpenTelemetry Go versioning and stability [policy](../../../../VERSIONING.md).
+These features may be removed or modified in successive version releases, including patch versions.
+
+When an experimental feature is promoted to a stable feature, a migration path will be included in the changelog entry of the release.
+There is no guarantee that any environment variable feature flags that enabled the experimental feature will be supported by the stable version.
+If they are supported, they may be accompanied with a deprecation notice stating a timeline for the removal of that support.

-Package reducer implements a metrics Processor component to reduce labels.
-
-This package is currently in a pre-GA phase. Backwards incompatible changes
-may be introduced in subsequent minor version releases as we work to track the
-evolving OpenTelemetry specification and user feedback.
-
-The metrics Processor component this package implements applies a
-`attribute.Filter` to each processed `export.Accumulation` to remove labels before
-passing the result to another Processor.  This Processor can be used to reduce
-inherent dimensionality in the data, as a way to control the cost of
-collecting high cardinality metric data.
-
-For example, to compose a push controller with a reducer and a basic
-metric processor:
-
-type someFilter struct{
-        // configuration for this filter
-        // ...
-}
-
-func (someFilter) LabelFilterFor(_ *sdkapi.Descriptor) attribute.Filter {
-        return func(label kv.KeyValue) bool {
-                // return true to keep this label, false to drop this label
-                // ...
-        }
-}
-
-func setupMetrics(exporter export.Exporter) (stop func()) {
-        basicProcessorFactory := basic.NewFactory(
-                simple.NewWithHistogramDistribution(),
-                exporter,
-        )
-
-        reducerProcessor := reducer.NewFactory(someFilter{...}, basicProcessorFactory)
-
-        controller := controller.New(
-                reducerProcessor,
-                exporter,
-                opts...,
-        )
-        controller.Start()
-        global.SetMeterProvider(controller.Provider())
-        return controller.Stop

+# API Implementations
+
+This package does not conform to the standard Go versioning policy; all of its
+interfaces may have methods added to them without a package major version bump.
+This non-standard API evolution could surprise an uninformed implementation
+author. They could unknowingly build their implementation in a way that would
+result in a runtime panic for their users that update to the new API.
+
+The API is designed to help inform an instrumentation author about this
+non-standard API evolution. It requires them to choose a default behavior for
+unimplemented interface methods. There are three behavior choices they can
+make:
+
+  - Compilation failure
+  - Panic
+  - Default to another implementation
+
+All interfaces in this API embed a corresponding interface from
+[go.opentelemetry.io/otel/trace/embedded]. If an author wants the default
+behavior of their implementations to be a compilation failure, signaling to
+their users they need to update to the latest version of that implementation,
+they need to embed the corresponding interface from
+[go.opentelemetry.io/otel/trace/embedded] in their implementation. For
+example,
+
+	import "go.opentelemetry.io/otel/trace/embedded"
+
+	type TracerProvider struct {
+		embedded.TracerProvider
+		// ...
+	}
+
+If an author wants the default behavior of their implementations to panic, they
+can embed the API interface directly.
+
+	import "go.opentelemetry.io/otel/trace"
+
+	type TracerProvider struct {
+		trace.TracerProvider
+		// ...
+	}
+
+This option is not recommended. It will lead to publishing packages that
+contain runtime panics when users update to newer versions of
+[go.opentelemetry.io/otel/trace], which may be done with a trasitive
+dependency.
+
+Finally, an author can embed another implementation in theirs. The embedded
+implementation will be used for methods not defined by the author. For example,
+an author who wants to default to silently dropping the call can use
+[go.opentelemetry.io/otel/trace/noop]:
+
+	import "go.opentelemetry.io/otel/trace/noop"
+
+	type TracerProvider struct {
+		noop.TracerProvider
+		// ...
+	}
+
+It is strongly recommended that authors only embed
+[go.opentelemetry.io/otel/trace/noop] if they choose this default behavior.
+That implementation is the only one OpenTelemetry authors can guarantee will
+fully implement all the API interfaces when a user updates their API.

+// TracerProvider provides Tracers that are used by instrumentation code to
+// trace computational workflows.
+//
+// A TracerProvider is the collection destination of all Spans from Tracers it
+// provides, it represents a unique telemetry collection pipeline. How that
+// pipeline is defined, meaning how those Spans are collected, processed, and
+// where they are exported, depends on its implementation. Instrumentation
+// authors do not need to define this implementation, rather just use the
+// provided Tracers to instrument code.
 //
-// Warning: methods may be added to this interface in minor releases.
+// Commonly, instrumentation code will accept a TracerProvider implementation
+// at runtime from its users or it can simply use the globally registered one
+// (see https://pkg.go.dev/go.opentelemetry.io/otel#GetTracerProvider).
+//
+// Warning: Methods may be added to this interface in minor releases. See
+// package documentation on API implementation for information on how to set
+// default behavior for unimplemented methods.

-	// Tracer creates an implementation of the Tracer interface.
-	// The instrumentationName must be the name of the library providing
-	// instrumentation. This name may be the same as the instrumented code
-	// only if that code provides built-in instrumentation. If the
-	// instrumentationName is empty, then a implementation defined default
-	// name will be used instead.

+	// Tracer returns a unique Tracer scoped to be used by instrumentation code
+	// to trace computational workflows. The scope and identity of that
+	// instrumentation code is uniquely defined by the name and options passed.
+	//
+	// The passed name needs to uniquely identify instrumentation code.
+	// Therefore, it is recommended that name is the Go package name of the
+	// library providing instrumentation (note: not the code being
+	// instrumented). Instrumentation libraries can have multiple versions,
+	// therefore, the WithInstrumentationVersion option should be used to
+	// distinguish these different codebases. Additionally, instrumentation
+	// libraries may sometimes use traces to communicate different domains of
+	// workflow data (i.e. using spans to communicate workflow events only). If
+	// this is the case, the WithScopeAttributes option should be used to
+	// uniquely identify Tracers that handle the different domains of workflow
+	// data.
+	//
+	// If the same name and options are passed multiple times, the same Tracer
+	// will be returned (it is up to the implementation if this will be the
+	// same underlying instance of that Tracer or not). It is not necessary to
+	// call this multiple times with the same name and options to get an
+	// up-to-date Tracer. All implementations will ensure any TracerProvider
+	// configuration changes are propagated to all provided Tracers.
+	//
+	// If name is empty, then an implementation defined default name will be
+	// used instead.
 	//
-	// This method must be concurrency safe.
-	Tracer(instrumentationName string, opts ...TracerOption) Tracer
+	// This method is safe to call concurrently.

-title: "Processing and Exporting Data"
-weight: 4
----
-
-Once you've instrumented your code, you need to get the data out in order to do anything useful with it. This page will cover the basics of the process and export pipeline.
-
-# Sampling
-
-Sampling is a process that restricts the amount of traces that are generated by a system. The exact sampler you should use depends on your specific needs, but in general you should make a decision at the start of a trace, and allow the sampling decision to propagate to other services.
-
-A sampler needs to be set on the tracer provider when its configured, as follows:
-
-```go
-provider := sdktrace.NewTracerProvider(
-	sdktrace.WithSampler(sdktrace.AlwaysSample()),
-)
-```
-
-`AlwaysSample` and `NeverSample` are fairly self-explanatory. Always means that every trace will be sampled, the converse holds as true for Never. When you're getting started, or in a development environment, you'll almost always want to use `AlwaysSample`.
-
-Other samplers include:
-
-* `TraceIDRatioBased`, which will sample a fraction of traces, based on the fraction given to the sampler. Thus, if you set this to .5, half of traces will be sampled.
-* `ParentBased`, which behaves differently based on the incoming sampling decision. In general, this will sample spans that have parents that were sampled, and will not sample spans whose parents were _not_ sampled.
-
-When you're in production, you should consider using the `TraceIDRatioBased` sampler with the `ParentBased` sampler.
-
-# Resources
-
-Resources are a special type of attribute that apply to all spans generated by a process. These should be used to represent underlying metadata about a process that's non-ephemeral - for example, the hostname of a process, or its instance ID.
-
-Resources should be assigned to a tracer provider at its initialization, and are created much like attributes:
-
-```go
-resources := resource.NewWithAttributes(
-	semconv.SchemaURL,
-	semconv.ServiceNameKey.String("myService"),
-	semconv.ServiceVersionKey.String("1.0.0"),
-	semconv.ServiceInstanceIDKey.String("abcdef12345"),
-)
-
-provider := sdktrace.NewTracerProvider(
-	...
-	sdktrace.WithResource(resources),
-)
-```
-
-Note the use of the `semconv` package to provide conventional names for resource attributes.  This helps ensure that consumers of telemetry produced with these semantic conventions can
-easily discover relevant attributes and understand their meaning.
-
-Resources can also be detected automatically through `resource.Detector` implementations.  These `Detector`s may discover information about the currently running process, the operating
-system it is running on, the cloud provider hosting that operating system instance, or any number of other resource attributes.
-
-```go
-resources := resource.New(context.Background(),
-	// Builtin detectors provide default values and support
-	// OTEL_RESOURCE_ATTRIBUTES and OTEL_SERVICE_NAME environment variables
-	resource.WithBuiltinDetectors(),
-	resource.WithProcess(), // This option configures a set of Detectors that discover process information
-	resource.WithDetectors(thirdparty.Detector{}), // Bring your own external Detector implementation
-	resource.WithAttributes(attribute.String("foo", "bar")), // Or specify resource attributes directly
-)
-```
-
-# OTLP Exporter
-
-OpenTelemetry Protocol (OTLP) export is available in the `go.opentelemetry.io/otel/exporters/otlp/otlptrace` and `go.opentelemetry.io/otel/exporters/otlp/otlpmetrics` packages.
-
-Please find more documentation on [GitHub](https://github.com/open-telemetry/opentelemetry-go/tree/main/exporters/otlp)
-
-# Jaeger Exporter
-
-Jaeger export is available in the `go.opentelemetry.io/otel/exporters/jaeger` package.
-
-Please find more documentation on [GitHub](https://github.com/open-telemetry/opentelemetry-go/tree/main/exporters/jaeger)
-
-# Prometheus Exporter
-
-Prometheus export is available in the `go.opentelemetry.io/otel/exporters/prometheus` package.

-title: "Getting Started"
-weight: 2
----
-
-Welcome to the OpenTelemetry for Go getting started guide! This guide will walk you through the basic steps in installing, instrumenting with, configuring, and exporting data from OpenTelemetry. Before you get started, be sure to have Go 1.16 or newer installed.
-
-Understand how a system is functioning when it is failing or having issues is critical to resolving those issues. One strategy to understand this is with tracing. This guide shows how the OpenTelemetry Go project can be used to trace an example application. You will start with an application that computes Fibonacci numbers for users, and from there you will add instrumentation to produce tracing telemetry with OpenTelemetry Go.
-
-To start building the application, make a new directory named `fib` to house our Fibonacci project. Next, add the following to a new file named `fib.go` in that directory.
-
-```go
-package main
-
-// Fibonacci returns the n-th fibonacci number.
-func Fibonacci(n uint) (uint64, error) {
-	if n <= 1 {
-		return uint64(n), nil
-	}
-
-	var n2, n1 uint64 = 0, 1
-	for i := uint(2); i < n; i++ {
-		n2, n1 = n1, n1+n2
-	}
-
-	return n2 + n1, nil
-}
-```
-
-With your core logic added, you can now build your application around it. Add a new `app.go` file with the following application logic.
-
-```go
-package main
-
-import (
-	"context"
-	"fmt"
-	"io"
-	"log"
-)
-
-// App is a Fibonacci computation application.
-type App struct {
-	r io.Reader
-	l *log.Logger
-}
-
-// NewApp returns a new App.
-func NewApp(r io.Reader, l *log.Logger) *App {
-	return &App{r: r, l: l}
-}
-
-// Run starts polling users for Fibonacci number requests and writes results.
-func (a *App) Run(ctx context.Context) error {
-	for {
-		n, err := a.Poll(ctx)
-		if err != nil {
-			return err
-		}
-
-		a.Write(ctx, n)
-	}
-}
-
-// Poll asks a user for input and returns the request.
-func (a *App) Poll(ctx context.Context) (uint, error) {
-	a.l.Print("What Fibonacci number would you like to know: ")
-
-	var n uint
-	_, err := fmt.Fscanf(a.r, "%d\n", &n)
-	return n, err
-}
-
-// Write writes the n-th Fibonacci number back to the user.
-func (a *App) Write(ctx context.Context, n uint) {
-	f, err := Fibonacci(n)
-	if err != nil {
-		a.l.Printf("Fibonacci(%d): %v\n", n, err)
-	} else {
-		a.l.Printf("Fibonacci(%d) = %d\n", n, f)
-	}
-}
-```
-
-With your application fully composed, you need a `main()` function to actually run the application. In a new `main.go` file add the following run logic.
-
-```go
-package main
-
-import (
-	"context"
-	"log"
-	"os"
-	"os/signal"
-)
-
-func main() {
-	l := log.New(os.Stdout, "", 0)
-
-	sigCh := make(chan os.Signal, 1)
-	signal.Notify(sigCh, os.Interrupt)
-
-	errCh := make(chan error)
-	app := NewApp(os.Stdin, l)
-	go func() {
-		errCh <- app.Run(context.Background())
-	}()
-
-	select {
-	case <-sigCh:
-		l.Println("\ngoodbye")
-		return
-	case err := <-errCh:
-		if err != nil {
-			l.Fatal(err)
-		}
-	}
-}
-```
-
-With the code complete it is almost time to run the application. Before you can do that you need to initialize this directory as a Go module. From your terminal, run the command `go mod init fib` in the `fib` directory. This will create a `go.mod` file, which is used by Go to manage imports. Now you should be able to run the application!
-
-```sh
-$ go run .
-What Fibonacci number would you like to know:
-42
-Fibonacci(42) = 267914296
-What Fibonacci number would you like to know:
-^C
-goodbye
-```
-
-The application can be exited with CTRL+C. You should see a similar output as above, if not make sure to go back and fix any errors.
-
-# Trace Instrumentation
-
-OpenTelemetry is split into two parts: an API to instrument code with, and SDKs that implement the API. To start integrating OpenTelemetry into any project, the API is used to define how telemetry is generated. To generate tracing telemetry in your application you will use the OpenTelemetry Trace API from the `go.opentelemetry.io/otel/trace` package.
-
-First, you need to install the necessary packages for the Trace API. Run the following command in your working directory.
-
-```sh
-go get go.opentelemetry.io/otel \
-       go.opentelemetry.io/otel/trace
-```
-
-Now that the packages installed you can start updating your application with imports you will use in the `app.go` file.
-
-```go
-import (
-	"context"
-	"fmt"
-	"io"
-	"log"
-	"strconv"
-
-	"go.opentelemetry.io/otel"
-	"go.opentelemetry.io/otel/attribute"
-	"go.opentelemetry.io/otel/trace"
-)
-```
-
-With the imports added, you can start instrumenting.
-
-The OpenTelemetry Tracing API provides a `Tracer` to create traces. These `Tracer`s are designed to be associated with one instrumentation library. That way telemetry they produce can be understood to come from that part of a code base. To uniquely identify your application to the `Tracer` you will use create a constant with the package name in `app.go`.
-
-```go
-// name is the Tracer name used to identify this instrumentation library.
-const name = "fib"
-```
-
-Using the full-qualified package name, something that should be unique for Go packages, is the standard way to identify a `Tracer`. If your example package name differs, be sure to update the name you use here to match.
-
-Everything should be in place now to start tracing your application. But first, what is a trace? And, how exactly should you build them for you application?
-
-To back up a bit, a trace is a type of telemetry that represents work being done by a service. A trace is a record of the connection(s) between participants processing a transaction, often through client/server requests processing and other forms of communication.
-
-Each part of the work that a service performs is represented in the trace by a span. Those spans are not just an unordered collection. Like the call stack of our application, those spans are defined with relationships to one another. The "root" span is the only span without a parent, it represents how a service request is started. All other spans have a parent relationship to another span in the same trace.
-
-If this last part about span relationships doesn't make complete sense now, don't worry. The most important takeaway is that each part of your code, which does some work, should be represented as a span. You will have a better understanding of these span relationships after you instrument your code, so let's get started.
-
-Start by instrumenting the `Run` method.
-
-```go
-// Run starts polling users for Fibonacci number requests and writes results.
-func (a *App) Run(ctx context.Context) error {
-	for {
-		var span trace.Span
-		ctx, span = otel.Tracer(name).Start(ctx, "Run")
-
-		n, err := a.Poll(ctx)
-		if err != nil {
-			span.End()
-			return err
-		}
-
-		a.Write(ctx, n)
-		span.End()
-	}
-}
-```
-
-The above code creates a span for every iteration of the for loop. The span is created using a `Tracer` from the global `TracerProvider`. You will learn more about `TracerProvider`s and handle the other side of setting up a global `TracerProvider` when you install an SDK in a later section. For now, as an instrumentation author, all you need to worry about is that you are using an appropriately named `Tracer` from a `TracerProvider` when you write `otel.Tracer(name)`.
-
-Next, instrument the `Poll` method.
-
-```go
-// Poll asks a user for input and returns the request.
-func (a *App) Poll(ctx context.Context) (uint, error) {
-	_, span := otel.Tracer(name).Start(ctx, "Poll")
-	defer span.End()
-
-	a.l.Print("What Fibonacci number would you like to know: ")
-
-	var n uint
-	_, err := fmt.Fscanf(a.r, "%d", &n)
-
-	// Store n as a string to not overflow an int64.
-	nStr := strconv.FormatUint(uint64(n), 10)
-	span.SetAttributes(attribute.String("request.n", nStr))
-
-	return n, err
-}
-```
-
-Similar to the `Run` method instrumentation, this adds a span to the method to track the computation performed. However, it also adds an attribute to annotate the span. This annotation is something you can add when you think a user of your application will want to see the state or details about the run environment when looking at telemetry.
-
-Finally, instrument the `Write` method.
-
-```go
-// Write writes the n-th Fibonacci number back to the user.
-func (a *App) Write(ctx context.Context, n uint) {
-	var span trace.Span
-	ctx, span = otel.Tracer(name).Start(ctx, "Write")
-	defer span.End()
-
-	f, err := func(ctx context.Context) (uint64, error) {
-		_, span := otel.Tracer(name).Start(ctx, "Fibonacci")
-		defer span.End()
-		return Fibonacci(n)
-	}(ctx)
-	if err != nil {
-		a.l.Printf("Fibonacci(%d): %v\n", n, err)
-	} else {
-		a.l.Printf("Fibonacci(%d) = %d\n", n, f)
-	}
-}
-```
-
-This method is instrumented with two spans. One to track the `Write` method itself, and another to track the call to the core logic with the `Fibonacci` function. Do you see how context is passed through the spans? Do you see how this also defines the relationship between spans?
-
-In OpenTelemetry Go the span relationships are defined explicitly with a `context.Context`. When a span is created a context is returned alongside the span. That context will contain a reference to the created span. If that context is used when creating another span the two spans will be related. The original span will become the new span's parent, and as a corollary, the new span is said to be a child of the original. This hierarchy gives traces structure, structure that helps show a computation path through a system. Based on what you instrumented above and this understanding of span relationships you should expect a trace for each execution of the run loop to look like this.
-
-```
-Run
-├── Poll
-└── Write
-    └── Fibonacci
-```
-
-A `Run` span will be a parent to both a `Poll` and `Write` span, and the `Write` span will be a parent to a `Fibonacci` span.
-
-Now how do you actually see the produced spans? To do this you will need to configure and install an SDK.
-
-# SDK Installation
-
-OpenTelemetry is designed to be modular in its implementation of the OpenTelemetry API. The OpenTelemetry Go project offers an SDK package, `go.opentelemetry.io/otel/sdk`, that implements this API and adheres to the OpenTelemetry specification. To start using this SDK you will first need to create an exporter, but before anything can happen we need to install some packages. Run the following in the `fib` directory to install the trace STDOUT exporter and the SDK.
-
-```sh
-$ go get go.opentelemetry.io/otel/sdk \
-         go.opentelemetry.io/otel/exporters/stdout/stdouttrace
-```
-
-Now add the needed imports to `main.go`.
-
-```go
-import (
-	"context"
-	"io"
-	"log"
-	"os"
-
-	"go.opentelemetry.io/otel"
-	"go.opentelemetry.io/otel/exporters/stdout/stdouttrace"
-	"go.opentelemetry.io/otel/sdk/trace"
-)
-```
-
-## Creating a Console Exporter
-
-The SDK connects telemetry from the OpenTelemetry API to exporters. Exporters are packages that allow telemetry data to be emitted somewhere - either to the console (which is what we're doing here), or to a remote system or collector for further analysis and/or enrichment. OpenTelemetry supports a variety of exporters through its ecosystem including popular open source tools like Jaeger, Zipkin, and Prometheus.
-
-To initialize the console exporter, add the following function to the `main.go` file:
-
-```go
-// newExporter returns a console exporter.
-func newExporter(w io.Writer) (trace.SpanExporter, error) {
-	return stdouttrace.New(
-		stdouttrace.WithWriter(w),
-		// Use human-readable output.
-		stdouttrace.WithPrettyPrint(),
-		// Do not print timestamps for the demo.
-		stdouttrace.WithoutTimestamps(),
-	)
-}
-```
-
-This creates a new console exporter with basic options. You will use this function later when you configure the SDK to send telemetry data to it, but first you need to make sure that data is identifiable.
-
-## Creating a Resource
-
-Telemetry data can be crucial to solving issues with a service. The catch is, you need a way to identify what service, or even what service instance, that data is coming from. OpenTelemetry uses a `Resource` to represent the entity producing telemetry. Add the following function to the `main.go` file to create an appropriate `Resource` for the application.
-
-```go
-// newResource returns a resource describing this application.
-func newResource() *resource.Resource {
-	r, _ := resource.Merge(
-		resource.Default(),
-		resource.NewWithAttributes(

-Any information you would like to associate with all telemetry data the SDK handles can be added to the returned `Resource`. This is done by registering the `Resource` with the `TracerProvider`. Something you can now create!
-
-## Installing a Tracer Provider
-
-You have your application instrumented to produce telemetry data and you have an exporter to send that data to the console, but how are they connected? This is where the `TracerProvider` is used. It is a centralized point where instrumentation will get a `Tracer` from and funnels the telemetry data from these `Tracer`s to export pipelines.
-
-The pipelines that receive and ultimately transmit data to exporters are called `SpanProcessor`s. A `TracerProvider` can be configured to have multiple span processors, but for this example you will only need to configure only one. Update your `main` function in `main.go` with the following.
-
-```go
-func main() {
-	l := log.New(os.Stdout, "", 0)
-
-	// Write telemetry data to a file.
-	f, err := os.Create("traces.txt")
-	if err != nil {
-		l.Fatal(err)
-	}
-	defer f.Close()
-
-	exp, err := newExporter(f)
-	if err != nil {
-		l.Fatal(err)
-	}
-
-	tp := trace.NewTracerProvider(
-		trace.WithBatcher(exp),
-		trace.WithResource(newResource()),
-	)
-	defer func() {
-		if err := tp.Shutdown(context.Background()); err != nil {
-			l.Fatal(err)
-		}
-	}()
-	otel.SetTracerProvider(tp)
-
-    /* … */
-}
-```
-
-There's a fair amount going on here. First you are creating a console exporter that will export to a file. You are then registering the exporter with a new `TracerProvider`. This is done with a `BatchSpanProcessor` when it is passed to the `trace.WithBatcher` option. Batching data is a good practice and will help not overload systems downstream. Finally, with the `TracerProvider` created, you are deferring a function to flush and stop it, and registering it as the global OpenTelemetry `TracerProvider`.
-
-Do you remember in the previous instrumentation section when we used the global `TracerProvider` to get a `Tracer`? This last step, registering the `TracerProvider` globally, is what will connect that instrumentation's `Tracer` with this `TracerProvider`. This pattern, using a global `TracerProvider`, is convenient, but not always appropriate. `TracerProvider`s can be explicitly passed to instrumentation or inferred from a context that contains a span. For this simple example using a global provider makes sense, but for more complex or distributed codebases these other ways of passing `TracerProvider`s may make more sense.
-
-# Putting It All Together
-
-You should now have a working application that produces trace telemetry data! Give it a try.
-
-```sh
-$ go run .
-What Fibonacci number would you like to know:
-42
-Fibonacci(42) = 267914296
-What Fibonacci number would you like to know:
-^C
-goodbye
-```
-
-A new file named `traces.txt` should be created in your working directory. All the traces created from running your application should be in there!
-
-# (Bonus) Errors
-
-At this point you have a working application and it is producing tracing telemetry data. Unfortunately, it was discovered that there is an error in the core functionality of the `fib` module.
-
-```sh
-$ go run .
-What Fibonacci number would you like to know:
-100
-Fibonacci(100) = 3736710778780434371
-# …
-```
-
-But the 100-th Fibonacci number is `354224848179261915075`, not `3736710778780434371`! This application is only meant as a demo, but it shouldn't return wrong values. Update the `Fibonacci` function to return an error instead of computing incorrect values.
-
-```go
-// Fibonacci returns the n-th fibonacci number. An error is returned if the
-// fibonacci number cannot be represented as a uint64.
-func Fibonacci(n uint) (uint64, error) {
-	if n <= 1 {
-		return uint64(n), nil
-	}
-
-	if n > 93 {
-		return 0, fmt.Errorf("unsupported fibonacci number %d: too large", n)
-	}
-
-	var n2, n1 uint64 = 0, 1
-	for i := uint(2); i < n; i++ {
-		n2, n1 = n1, n1+n2
-	}
-
-	return n2 + n1, nil
-}
-```
-
-Great, you have fixed the code, but it would be ideal to include errors returned to a user in the telemetry data. Luckily, spans can be configured to communicate this information. Update the `Write` method in `app.go` with the following code.
-
-```go
-// Write writes the n-th Fibonacci number back to the user.
-func (a *App) Write(ctx context.Context, n uint) {
-	var span trace.Span
-	ctx, span = otel.Tracer(name).Start(ctx, "Write")
-	defer span.End()
-
-	f, err := func(ctx context.Context) (uint64, error) {
-		_, span := otel.Tracer(name).Start(ctx, "Fibonacci")
-		defer span.End()
-		f, err := Fibonacci(n)
-		if err != nil {
-			span.RecordError(err)
-			span.SetStatus(codes.Error, err.Error())
-		}
-		return f, err
-	}(ctx)
-    /* … */
-}
-```
-
-With this change any error returned from the `Fibonacci` function will mark that span as an error and record an event describing the error.
-
-This is a great start, but it is not the only error returned in from the application. If a user makes a request for a non unsigned integer value the application will fail. Update the `Poll` method with a similar fix to capture this error in the telemetry data.
-
-```go
-// Poll asks a user for input and returns the request.
-func (a *App) Poll(ctx context.Context) (uint, error) {
-	_, span := otel.Tracer(name).Start(ctx, "Poll")
-	defer span.End()
-
-	a.l.Print("What Fibonacci number would you like to know: ")
-
-	var n uint
-	_, err := fmt.Fscanf(a.r, "%d", &n)
-	if err != nil {
-		span.RecordError(err)
-		span.SetStatus(codes.Error, err.Error())
-		return 0, err
-	}
-
-	// Store n as a string to not overflow an int64.
-	nStr := strconv.FormatUint(uint64(n), 10)
-	span.SetAttributes(attribute.String("request.n", nStr))
-
-	return n, nil
-}
-```
-
-All that is left is updating imports for the `app.go` file to include the `go.opentelemetry.io/otel/codes` package.
-
-```go
-import (
-	"context"
-	"fmt"
-	"io"
-	"log"
-	"strconv"
-
-	"go.opentelemetry.io/otel"
-	"go.opentelemetry.io/otel/attribute"
-	"go.opentelemetry.io/otel/codes"
-	"go.opentelemetry.io/otel/trace"
-)
-```
-
-With these fixes in place and the instrumentation updated, re-trigger the bug.
-
-```sh
-$ go run .
-What Fibonacci number would you like to know:
-100
-Fibonacci(100): unsupported fibonacci number 100: too large
-What Fibonacci number would you like to know:
-^C
-goodbye
-```
-
-Excellent! The application no longer returns wrong values, and looking at the telemetry data in the `traces.txt` file you should see the error captured as an event.
-
-```
-"Events": [
-	{
-		"Name": "exception",
-		"Attributes": [
-			{
-				"Key": "exception.type",
-				"Value": {
-					"Type": "STRING",
-					"Value": "*errors.errorString"
-				}
-			},

-				"Key": "exception.message",
-				"Value": {
-					"Type": "STRING",
-					"Value": "unsupported fibonacci number 100: too large"
-				}
-			}
-		],
-        ...
-    }
-]
-```

-are many other topics to cover in OpenTelemetry, but you should be ready to
-start adding OpenTelemetry Go to your projects at this point. Go instrument your

-title: Instrumentation
-weight: 3
----
-
-Instrumentation is the process of adding observability code to your application. There are two general types of instrumentation - automatic, and manual - and you should be familiar with both in order to effectively instrument your software.
-
-# Creating Spans
-
-Spans are created by tracers, which can be acquired from a Tracer Provider.
-
-```go
-ctx := context.Background()
-tracer := otel.Tracer("example/main")
-var span trace.Span
-ctx, span = tracer.Start(ctx, "helloWorld")
-defer span.End()
-```
-
-In Go, the `context` package is used to store the active span. When you start a span, you'll get a handle on not only the span that's created, but the modified context that contains it. When starting a new span using this context, a parent-child relationship will automatically be created between the two spans, as seen here:
-
-```go
-func parentFunction() {
-	ctx := context.Background()
-	var parentSpan trace.Span
-	ctx, parentSpan = tracer.Start(ctx, "parent")
-	defer parentSpan.End()
-	// call our child function
-	childFunction(ctx)
-	// do more work, when this function ends, parentSpan will complete.
-}
-
-func childFunction(ctx context.Context) {
-	var childSpan trace.Span
-	ctx, childSpan = tracer.Start(ctx, "child")
-	defer childSpan.End()
-	// do work here, when this function returns, childSpan will complete.
-}
-```
-
-Once a span has completed, it is immutable and can no longer be modified.
-
-## Attributes
-
-Attributes are keys and values that are applied as metadata to your spans and are useful for aggregating, filtering, and grouping traces. Attributes can be added at span creation, or at any other time during the lifecycle of a span before it has completed.
-
-```go
-// setting attributes at creation...
-ctx, span = tracer.Start(ctx, "attributesAtCreation", trace.WithAttributes(attribute.String("hello", "world")))
-// ... and after creation
-span.SetAttributes(attribute.Bool("isTrue", true), attribute.String("stringAttr", "hi!"))
-```
-
-Attribute keys can be precomputed, as well -
-
-```go
-var myKey = attribute.Key("myCoolAttribute")
-span.SetAttributes(myKey.String("a value"))
-```
-
-### Semantic Attributes
-
-Semantic Attributes are attributes that are defined by the [OpenTelemetry Specification][] in order to provide a shared set of attribute keys across multiple languages, frameworks, and runtimes for common concepts like HTTP methods, status codes, user agents, and more. These attributes are available in the `go.opentelemetry.io/otel/semconv/v1.7.0` package.
-
-For details, see [Trace semantic conventions][].
-
-## Events
-
-An event is a human-readable message on a span that represents "something happening" during it's lifetime. For example, imagine a function that requires exclusive access to a resource that is under a mutex. An event could be created at two points - once, when we try to gain access to the resource, and another when we acquire the mutex.
-
-```go
-span.AddEvent("Acquiring lock")
-mutex.Lock()
-span.AddEvent("Got lock, doing work...")
-// do stuff
-span.AddEvent("Unlocking")
-mutex.Unlock()
-```
-
-A useful characteristic of events is that their timestamps are displayed as offsets from the beginning of the span, allowing you to easily see how much time elapsed between them.
-
-Events can also have attributes of their own -
-
-```go
-span.AddEvent("Cancelled wait due to external signal", trace.WithAttributes(attribute.Int("pid", 4328), attribute.String("signal", "SIGHUP")))
-```
-
-# Creating Metrics
-
-The metrics API is currently unstable, documentation TBA.
-
-# Propagators and Context
-
-Traces can extend beyond a single process. This requires _context propagation_, a mechanism where identifiers for a trace are sent to remote processes.
-
-In order to propagate trace context over the wire, a propagator must be registered with the OpenTelemetry API.
-
-```go
-import (
-  "go.opentelemetry.io/otel"
-  "go.opentelemetry.io/otel/propagation"
-)
-...
-otel.SetTextMapPropagator(propagation.TraceContext{})
-```
-
-> OpenTelemetry also supports the B3 header format, for compatibility with existing tracing systems (`go.opentelemetry.io/contrib/propagators/b3`) that do not support the W3C TraceContext standard.
-
-After configuring context propagation, you'll most likely want to use automatic instrumentation to handle the behind-the-scenes work of actually managing serializing the context.
-
-# Automatic Instrumentation
-
-Automatic instrumentation, broadly, refers to instrumentation code that you didn't write. OpenTelemetry for Go supports this process through wrappers and helper functions around many popular frameworks and libraries. You can find a current list [here](https://github.com/open-telemetry/opentelemetry-go-contrib/tree/main/instrumentation), as well as at the [registry](/registry).
