FYI : This is documented at http://www.datanucleus.org/products/accessplatform_4_2/jdo/orm/datastor e_identifiers.html The JPA spec defines what column names should default to. The JDO spec does not, so DataNucleus provides 4 alternatives (default = "datanucleus2"), but you also have "jpa", "datanucleus1" and (for those with very old code) "jpox". And if sufficiently interested in there being a JDO spec definition of the default then kindly participate in Apache JDO issue https://issues.apache.org/jira/browse/JDO-727 Regards -- Andy DataNucleus (Web: http://www.datanucleus.org Twitter: @datanucleus)
