Jenny, (01)
I just want to emphasize that I'm definitely in favor of
having common ontologies when they are useful for their
intended purpose. (02)
But as your example shows, it is not a good idea to force
commonality where it is inappropriate: (03)

Commonality is not an end in itself. My greatest fear about any
kind of universal ontology is that (a) people will try to force it
on projects where it does more harm than good, and (b) the result
will be that it destroys the credibility of the entire field. (05)

That is a very reasonable approach. (07)
