The problem is, would be end up using UML, or a UML-like notation (as
we did in the conceptual model). If the latter, UML devolves from a
formalism to prose + illustrations -- not that there's anything wrong
with that....

I'm concerned about all the constituencies -- RDF is not specified in
UML (why?). Will a UML model give the TMQL people what they need to
query against?
