About This Documentation
EclipseLink provides the reference implementation of the Java Persistence Architecture (JPA) 2.0 specification. It also includes many enhancements and extensions. This documentation primarily documents the EclipseLink enhancements and extensions to JPA. Please refer to the JPA specification for full documentation of core JPA. Where appropriate, this documentation provides links to the pertinent section of the specification.

- See Basic JPA Development for more information about EclipseLink support of JPA.
- See the [Java Persistence 2.0] specification for complete core JPA documentation.
- See the [| EclipeLink Javadoc] for complete EclipseLink JPA API reference documentation, including core JPA plus the EclipseLink enhancements:
- Core JPA include the javax.persistence.* packages.
- EclipseLink JPA enhancements include the org.eclipse.persistence.* packages.
- See the XML schemas that define the elements used for configuring persistence units and mappings:
- persistence_2_0.xsd is the the schema for the JPA persistence configuration file.
- orm_2_0.xsd is the schema for the persistence object/relational mapping file.
- eclipselink_orm_2_0.xsd is the schema for the native EclipseLink mapping file.
- See the The Java EE 5 Tutorial Part V, Persistence, for useful task-based information to help you implement JPA 2.0 applications. This tutorial does not include EclipseLink-specific information, but it contains much useful information about JPA 2.0
