I tend to agree with Todd. (01)
John - what is your rationale for considering the issues you raise (within OOR)? (02)

John, (05)
Some answers to your questions in the context of the OOR
and the current requirements (and expectations). (06)

--->>> The OOR is not attempting to explicitly define what an
ontology is or isn't. It will try to promote best practices
on the use of standards based representation languages,
though the extent of the best practices and their enforcement
of will likely fall to the implementer of the specification.
However, if the OOR team becomes more efficient we may be able
to provide a minimum set of (formal) policies embodying some
best practices. (08)

define this. (010)

I don't mean to disappoint you with these answers but I think
they are correct with respect to the OOR. If there ever is a
resolution among these notions, then OOR could consider addressing
them. (017)
The questions about terminology, interpretations, and ontologies
may be best answered or discussed on the Ontolog forum. As I've
pointed out to others, many people using ontologies or
even developing them don't seem to demonstrate an
understanding of 'interpretation' (the FOL model theoretic
version anyway). This lack of understanding manifests
itself in failures to sufficiently constrain the
interpretation of terms in their ontologies coupled
with the expectation that any non-explicit constraints
required to meet the intended interpretation come from
the deployment environment (i.e., implicit constraints). (018)
