Re: OODBMS <-> RDF

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?
