You made a number of points where I, personally, agree more than I disagree.

Well, I certainly don't support the aspersions against those who think
otherwise. However, I do agree that we are not going to get a consensus
standard ontology for anything particularly broad very soon.

Again, without buying the tone and phrasing, I agree with the content.
I think it would be a bad thing if this meeting, or any series of meetings,
was to try to define an "official" domain-specific ontology.
AT THIS POINT, YOU -- AND ANY OTHER READERS -- MAY WANT TO KNOW HOW THE HELL
THE GUY COORDINATING THE KR STANDARDS EFFORT CAN BE AGREEING WITH YOU ON
Well, my personal view is that shared ontologies are possible with today's
knowledge representation technology -- but they will *evolve* rather than
being legislated. That is, standard shared ontologies will emerge out of a
marketplace -- people will use and refine ones that seem useful, and they
will become more useful in the process. I think they'll start small and
specific, rather than broad and general.
Thus, the only successful "standard" ontologies will be *de facto standards*.
I don't think it will happen by fiat.
I view our mission in the SRKB group as trying to see if we can get a
marketplace process started. Any work on content of ontologies is for the
purpose of seeding the process with some initial entries -- not as trying to
legislate the outcomes. (This is a personal opinion, about which reasonable
people can certainly differ.)
For that reason, I'm particularly in agreement when you say things like...

...My hope is that precisely the things we'll start talking about this weekend
are questions like this suggestion raises. What does someone need to know
about an ontology if they're going to try to reuse it? How can we help a
prospective user understand it, work within the spirit of its intended use,
etc? When an ontology doesn't fit, what gets done about it? In general, what
does it take to support a group that's trying to build and use a shared

It will be interesting to find out.

I look forward to meeting you this weekend.

Actually, I find the worst one is when people fall asleep while I'm talking. :-)
