I hope people don't mind if I take a drive-by comment I made in
another thread and make it a root message here, for people to shoot
down / agree / violently ignore as they see fit.
What I want to draw out here is, are there things about the purpose
of an ontology, which seem differently obvious to different people,
and if so, can and should these be articulated as a pre-requisite to
being able to verify or validate the resulting ontology?
Also I realize that Cory's point about enacting does't only
encompass semantic tech reasoning, but for many creators of
ontologies it does. So apologies if I'm mischaracterizing the
original points in order to make the quality assurance related
point.

Hi Cory,
...the entire point of ontologies is actually the formal clarity
of definition that other technologies lack.
Surely both of these is a point of an ontology. Neither of them is
the entire point, they are just the entire point of an ontology that
one or another person has created.
Part of knowing if an ontology does what it was intended to do, is
to have some clarity of what it is intended to do.
To some, being able to reason over an ontology and carry out
semantic technology applications is the only reason to do one, and
so for that ontology, that is the reason for it and the reason
against which one can determine if it is right or not. To others,
being able to formally pin down the meanings of concepts in some
domain (perhaps for formally specifying the terms that are to be
designed for in a database or message application, or perhaps not),
is the only reason for doing that ontology. So different
verification and validation measures would apply. In both cases,
it's wise to write down what you thought was obvious to everybody,
because (a) nothing is ever as obvious as you think and (b) it might
not have been the only reason to do a thing.
