thanks a lot for the pointer. In fact, I had the pleasure to discuss
some of the related issues with Stephen Cranefield on this list a while

Right. I feel that there is mutual benefit in embracing UML in the RDF
realm. On the other hand, MOF still offers room for simplification; RDF
comes handy here.

Absolutely! This I would say is the primary reason for doing UML/RDF.

I completely agree with your points. I'm looking forward to seeing the
above usage scenarious emerging as tomorrow's killer apps ;)
