  • Upgrade ODF, Excel, HBase, MongoDB plugins to start using persistable-identity

  • Clean up MetaDataManager and maybe make it an interface.
  • Move majority of schema operations from StoreManager to StoreSchemaHandler

  • Upgrade relevant store plugins to use Table/Column structure and benefit from common features, for ODF, Excel, JSON, MongoDB, Neo4j, HBase
  • Upgrade enhancement process to enhance to org.datanucleus.enhancer.Persistable so that users need to have datanucleus-core.jar in the CLASSPATH and not jdo-api.jar.
  • Drop EclipsePluginRegistry so all OSGi users should use OSGiPluginRegistry
  • Schema Evolution : restructure schema properties to allow for all we will need when adding/removing fields etc
