I said I was done with this thread.  I should clarify that I'm done with the, 
er, esoteric subthreads.  This is meat.

The DAML/OWL UnambiguousProperty class solves this problem directly.  If 
"ownerOf" is declared as an UnambiguousProperty, then your _:anon437 can be 
identified with JA's _:anon1 by axiom.

That having been said, I have no use for this trick because, in short, it's 
too Topic Mappish for me.
