Summary
In JPA 2.0 the specification has defined standard APIs for representing the structure of a persistence unit model. This is referred to at the MetaModel APIs. There are two main aspects to providing this functionality. The first is the runtime model accessed from EntityManagerFactory.getMetaModel() and the second is the APT generated meta model classes. Our first goal is to provide functionality for runtime access.
For details see section 5.2 and 5.3 of Proposed Final Draft.
