The Java library structr-core is the core of the structr framework. It encapsulates an embedded Neo4j database and provides means to access and manipulate data in it.

It can be used in a stand-alone scenario like this:

[ Application  |                  ]
[ structr-core | java-API |       ]
[ neo4j        | java-API         ]

Build with the usual maven commands (e.g. mvn clean install).

You cannot run structr-core stand-alone (it's a library).

Currently, there is no dedicated documentation available. Some documentation can be found in the dev-guide.

Additionally, you can take a look at the standard javadoc documentation here:
