Watching one of these from the sidelines can be very educational.

This implies that RDF and Topic Map bear a superset relationship to UML.

This would then imply that the superset relationship is not proper, after
having snuck XML Schema into the group with RDF and Topic Map. Rather
confusion logic, I'd say.

And I was very glad to see this assertion. I have long been under the
oppresion of object-mongers, even though I have doubted all along that
(programmable, ergo, tangible) objects were the be-all and end-all of

Sure, it is all matter, but that does not mean it is all objects that we can
get our hands or minds around.
