This package contains helper classes for the Keyring class. They are used to create more efficient mappings for Hibernate so that we can load group, role and project membership, and item, project and role keys, with less overhead.
This class/package is not part of the Public API
The mappings are only used for reading information from the database. For writing we use the "real" mappings in the KeyData class and it's subclasses.

Since XDoclet cannot generate composite-id elements we don't use javadoc tags in these classes. We have to write the XML mapping files for hibernate ourselves.
