But the following sentence raises some very important issues
that have never been settled (or even adequately discussed,
despite the many years of SUO list): (04)
> This methodology does apply to upper/middle ontologies, but

Every one of the following terms (extracted from that sentence)
is highly controversial and poorly defined: (06)
methodology, upper ontology, middle ontology, integration,
complex integration, interoperability. (07)
Furthermore, the relationships among those terms and their
implications for one another are even more controversial
and less well defined. (08)
> In a more disciplined world, the competency questions would
> be associated with the given ontology, to facilitate reuse. (09)
That sentence introduces additional controversial and poorly
defined terms whose relationships to the above and to one
another are just as problematical: (010)
disciplined world, competency, reuse. (011)
> I am working currently on a chapter on ontology architecture
> that addresses some of these issues. (012)
Good luck. If I may add a suggestion, I would recommend that the
architecture be highly flexible and extensible -- because it is
almost certain that it will have to undergo lots of revisions. (013)
