The test went well. I used Sesame 1.2.3 as repository and used XStream
to serialize our Java objects to XML and then used the object id's as
subjects, "urn:data" as predicate, and the stringified XML as object.
Worked like a charm, with equal or better performance than the previous
persistence store (which was a serialized binary database, Jisp, works
kind of like BerkeleyDB).

The next step for me is to index various XPath's in the serialized XML
as RDF properties of the object, and then all of a sudden we can do some
very very very cool queries on our entire object model, not to mention
handle versioning of object models trivially (by using
"urn:data:<version>" as predicate).

This Semantic Web crap seems to be working out pretty nicely.
