This repository is a component of the Java library which implements the Java object model for the System Package Data Exchange (SPDX) and provides useful helper functions.

This repository contains core files used as a base and common to all model files.

The API documentation is available at: https://spdx.github.io/spdx-java-core/

Please refer to the Spdx-Java-Library for information on how to use the code in this repository.

Contributions are welcome. See CONTRIBUTING.md.

The primary class in the core library is the CoreModelObject. All SPDX model classes inherit this class. It contains several useful functions including the ability to compare to other CoreModelObjects, add/remove properties, and manage collections.

Each major version of the SPDX specification should generate its own set of classes which inherit from the CoreModelObject.

Below is a simplified class model diagram which includes example SPDX model versions:

Very much under development and not very stable.
