| + | |
| − | # the database contains the specified entities: the typical scenario where the Project's entities are exposed via a RESTful CRUD application.

| + | |
| − | # meta-data describing the specified entities is provided through an alternative mechanism: the scenario where the Project's entities are described via a JPA <tt>.orm</tt> file.
