Correct. (cc'ing Stu Weibel PI and Harry Wagner (who did all the coding
:) from OCLC / DCMI).

OCLC - RDF Schema Interoperability

Demonstrate benefits common descriptive framework and common semantics
for supporting "recombinant metadata"

Integrate collections of diverse data into coherent whole

Stitched together descriptive information based on machine processable
relationships (e.g. rdfs:subPropertyOf dc:title)

Data partners include: AMICO, FAO, GEM, OAI (in XML/RDF), AGLS, RSS

Example Application - Semantic Merge

The last phase was putting in place the Semantic Merge demonstration -
http://wip.dublincore.org:8080/interop/searchServlet

The code for this is available under the Dublin Core Open Source license
but not sure the specific reference. Harry, can you provide a pointer? 
Availability of the instance data as I recall was an issue. The status
of which I'm not sure of.

I'm afraid that given finite resources and infinite opportunities, this
project has been on hold for the past several montsh.  That being said,
every time I present this work its met with increased interest and
enthusiasm for RDF and DC. As you've identified, its directly related to
some of the Simile deliverables and as such I'd very much like to see
this work continued.
