Extensions : MetaData Handler
DataNucleus has supported JDO metadata from the outset. More than this, it actually provides a pluggable framework whereby you can plug in your own MetaData support. DataNucleus provides JDO and JPA metadata support, as well as persistence.xml. You can extend DataNucleuss capabilities using the plugin extension org.datanucleus.metadata_handler.
