You are probably correct. One way to think about it is the fact that 
UML is basically a subset of "OWL" (the formal part) --- more 
concretely that OWL (the language) is an excellent way to write down 
UML models.

Of course this leads us to ask whether UML it either a) useful or b) 
accessible to ordinary mortals :-)

In any case, people who are already conversant in UML should find OWL 
not so intimidating.

This is the: tools will solve the problem idea.

I've said this before, but I personally believe that some way to 
combine the two is the key.

We are seeing more and more emphasis on semi structured search 
technologies melding the desktop and web: e.g. iTunes, Amazon and 
perhaps what Google intends for the desktop.
