The only other D2R like software I'm aware of is Squirrel RDF, http://jena.sourceforge.net/SquirrelRDF/. I don't know of any support of ZODB. Is something like RDF Alchemy, http://www.openvest.com/trac/wiki/RDFAlchemy, or Oort, http://oort.to/, similar to what you're looking for? 2008/1/25 José Pedro Ferreira <jose.pedro.ferreira@cern.ch>: > Hello. > Yes, I know that RDF can be seen as object-oriented.
