There is no single storage format for Jackrabbit. It depends on your configuration, mainly the PersistenceManager and DataStore. Typically a database persistence manager is used, for embedding it locally, the derby based PM is useful. See http://jackrabbit.apache.org/jackrabbit-configuration.html and http://wiki.apache.org/jackrabbit/PersistenceManagerFAQ There is no PM or DataStore that does compression. However, using a datastore can reduce required space as binaries are only stored once, regardless how often they are used in the repository. Regarding archiving: JCR itself provides versioning as part of its API and Jackrabbit supports it. Client applications must explicitly say when new versions should be created. > 4.

JCR supports workspaces for cloning/merging (search the mailing list for previous discussions on that). Regards, Alex -- Alexander Klimetschek [email protected]
