 The OWLDB takes a hibernate approach to creating a database backend for Protege.  There is a [http://owldb.sourceforge.net project page] and the svn sources for the project can be downloaded from [https://owldb.svn.sourceforge.net/svnroot/owldb/OWLDB-Core/trunk here].  The svn sources include some [https://owldb.svn.sourceforge.net/svnroot/owldb/OWLDB-Core/trunk/examples/de/fraunhofer/iitb/owldb/examples very simple examples] that  show how to setup the owldb.  The examples worked immediately for me.

 This page describes how you can access programmatically (add, query, modify) an ontology stored in one of the Protege 4 database backends. There are currently 2 backends: the OWL API v3 database backend developed at Stanford, and the [http://owldb.sourceforge.net/ OWLDB] database backend that is developed by external collaborators.
 This page focuses on the OWL API v3 backend. The documentation for the OWLDB backend is outdated and will be updated in future.
