The DataNucleus v3.1.0-m1 plugin for Neo4j has been released, introducing several new features including support for embedded and nested fields, querying of those fields, use of Neo4j node id as a global object identity, and JDOQL/JPQL ordering in Cypher. The plugin now offers improved functionality for working with Neo4j data using Java Persistence API (JPA) or Java Data Objects (JDO).
