INTEROP: Fwd: Re: Serendipitous Interoperability

This message was sent to me, Jim agreed to let me forward it to 
webont.  It is in response to Ora's posting this AM -- it has 
engendered some discussion on www-rdf-logic, and I would direct those 
interested to that list for further discussion of Jim's points. 
Discussion of Ora's points can be made here or there depending on 
your judgement of relevance to webont.
