Hello Mark and Alistair,

When writing my previous mail I was thinking of this term-as-class
solution, and actually found some additional drawbacks it might be
honest to include in the doc Mark wrote (though I still favour this
solution in a first move ;-) )

Actually what could happen with the term-as-class solution is the
creation of several instances of Terms referring actually to the same
term. If we assume that the link between Terms and their lexical
representation is "hasLexicalForm" (friends terminologists, please
forgive me ;-)) we could have, e.g. in the end of an automatic thesaurus
extraction process applied to the thing underlying alistair's example in
[1]

X hasLexicalForm "grinding mill" (from concept A) and 
Y hasLexicalForm "grinding mill" (from concept B)

So a best practice guide would have to advise developers so that they
avoid implementing tools producing such results (e.g. searching amongst
all the term to see if one has the lexical form which correspond to the
one of the Term to be introduced)
An alternative, and of course more elegant, solution would be to declare
the OWL version of this propery as "inverseFunctional": if two instances
are linked to a same lexical form, then they are equivalent. The problem
is that if we do that for a datatypeProperty (which hasLexicalform would
be) then we end in OWL Full. Which would perhaps make this solution less
interesting...

Cheers,

Antoine
