The open source Java persistence platform JPOX has become DataNucleus for its future direction, due to the significant changes in scope of the project since its initiation.
JPOX is a free and fully compliant implementation of the JDO1, JDO2, JDO2.1 and JPA1 specifications, providing transparent persistence of Java objects. JPOX passed JPA1 TCK in February 2008 making it a JPA compliant persistence framework. It supports persistence to most of the major RDBMS on the market today, persistence to the db4o object datastore, allows querying using either JDOQL, SQL, or JPQL, and comes with its own byte-code enhancer. It also complies with the OGC Simple Feature Specification for persistence of geospatial Java types. JPOX is available under the Open Source Apache 2 license.
DataNucleus extends the scope of JPOX to the application data management domain intent on supporting a wide range of datastores, APIs, services, as well as eventually providing data analysis tools. It is a standards-compliant Open Source Java persistence product which is fully compliant with the JDO1, JDO2, JDO2.1 and JPA1 Java standards. It also utilizes an OSGi-based plugin mechanism meaning that it is extensible.
DataNucleus Access Platform 1.0 ("Faraday") Milestone 1 takes the JPOX codebase and extends it with the following:
Moreover it allows a user to define their persistence using JDO XML/annotations or JPA XML/annotations and then utilize either the JDO or JPA API for persistence (no matter which persistence definition was used), and allow persistence to the full range of datastores.
On the DataNucleus site there are guides demonstrating integration with Eclipse, NetBeans, Maven and Ant.
DataNucleus products will be provided under the Apache 2 open source license.
