I believed that the point was that,
a domain ontology would, for most domains, especially scientific
ones, need to include references to special individuals,
Yes, but what is important is to unambiguously identify individuals
from classes. For that purpose the identity criteria introduced in
OntoClean is of utmost importance. For example:
like zero, -> criteria of identity: its symbol
like the chemical elements, -> criteria of
identity: its chemical symbol in the Mendeleev table
as individuals, like the earth, -> criteria of
identity: its name
..., like the U.S. Security and Exchange Commission
-> criteria of identity: its reference label
(the source of many of the definitions in the
ontology), and might likely also find it useful to include special
representative individuals, like certain rock samples.
not that the ontology would be indistinquishable from a knowlege
base for the domain, containing all the known facts about all the
known individuals.
I agree with Hassan and probably most that calling these things
TBox etc. was probably just a convenience for an email, not a
standard.
I also fully agree: there is a crucial difference between a tool and
a method.

Alex,
there is already a term for (2): *knowledge base*.
I agree. Why has a specific formalism terminology (namely
OWL's TBox, ABox, ...) become standard? There have been
generic names (Schema, Database, Knowledge Base, ...)
independent of any specific formalism - as it should be.
Especially when the formalism in question has evolved out of a
yet unproven fad when it concerns "real-life" scalable apps.

John,
Nicola reminds me 2 different definitions of ontology:
1. *>
2. *>
I prefer (2) as it keeps all knowledge together:-)
And it looks like Sandro keeps in mind (1).

And the wounded skies above say
it's much too much too late.
Well, maybe we should all be praying for time.
