Proposal:
JDO2 will define a complete set of annotations
Annotations will be declared in two different packages; jdo
annotations would contain only object model metadata, not mapping
metadata:
* javax.jdo.annotation.jdo
* javax.jdo.annotation.orm
Annotation documentation will focus on mapping between annotations
and the existing xml metadata and will use the identical semantics of
xml metadata
Compliant implementations that support JDK1.5 will be required to
accept annotated classes' metadata
If annotated classes are used with xml metadata, xml metadata will
override annotation metadata.
JDO2 will define interoperability with EJB3/JPA annotations
Compliant implementations can optionally use @Entity annotations
instead of JDO annotations
Mapping from EJB3/JPA to JDO will be defined so as to improve
portability of applications from one JDO implementation to others
If both JDO and EJB3/JPA annotations are used in the same class we
need to choose between:
+1
* JDO annotations will override EJB3/JPA annotations
+1
