...but do not *connote* the same thing, would be my term for it. E.g., 
the representations received when we enter each of the above in a 
browser may be different.

Each URI is specific to a particular intension: ok.
Each statement using the URI: Hm.

OWL specifies that if A owl:sameIndividualAs B, then all statements you 
can make about A entail a similar statement about B. E.g., if I say

     <http://example.com/EveningStar>  rdf:type  foo:BeautifulThing

then I'm implying that

     <http://example.com/Venus>   rdf:type   foo:BeautifulThing

I think that implying it is basically as good as saying it, so I think 
that it's not useful to say that the two statements are specific to a 
particular intension of the thing described, because if I make one of 
the statements, I also make the other (in RDF+OWL).

What do you think?
