Peter, Bill
I did not reply to Bills question cause I am still researching part of it
I believe two good papers make initial essential reading
- the ontology metamodel ( comparison with e/r for example and other stuffs)
- the model driven ontology engineering
sorry dont have the links on me
both papers differentiate and identify similaries between different, complementary models/views -
there is more published stuff out there, I am reading it
(and precision of _expression_ as provided by controlled vocabularies in
essential to ontology building, except perhaps for matematicians who
live in a world of formulas)
cheers

Data modelling is about, er, modelling data; it would follow that
ontology building is about building an ontology (small "o"). Data is not
the same as ontology; building is not the same as modelling. Sloppy
terminology and formulation for such a precise question, and on this
list of all places...! ;-)
Further, I don't understand why ontology building is an exercise in
application-specific modelling: I can build an ontology without giving a
damn about how it's used, where or by who - it's my encapsulated take on
reality and I can then *use* it to build something, if I choose: If you
switch your phrase around and talk rather about "ontology modelling" and
"application-specific building", it becomes clearer (to me at least).
Not so many moons ago, we had an extensive and intensive discussion
around the differences between data modelling and information modelling
- and now we have ontology modelling and, why not, concept modelling.
Would someone venture to distinguish, group, eliminate and add, as
appropriate?
Bill stated that:
"Surely it cannot be the use of this or that formalism which delivers
the desired interoperability properties."
At the Ontology Summit we talked about the "expressivity" of different
formalisms - presumably there is a significant difference in what
"desired interoperability properties" are delivered, as a function of
the expressiveness of the formalism you use, no?

Bill,
Would you provide us with your favourite satisfactory reply to this
question?
