I agree that we must have a clear statement of requirements from people
who have real problems. Ultimately, those requirements should originate
with the people who have the problems. The people who are developing KR
systems have a lot to say about what constructs are most effective for
addressing various requirements, but the requirements themselves must
come from the people with the problems.

The AI community is not a group of requirements generators, but a group
of people who are offering solutions. They may be well qualified to
judge how well different proposals can solve different problems. But
they are not qualified to say that the people who are clamoring for
standards should not have standards.
PDES and ANSI IRDS are two groups that are trying to address very clear
and distinct problems. If you want forcing functions to test proposed
solutions, it is hard to find any other groups with more serious
requirements for knowledge sharing.

Last year at this time, the DARPA knowledge sharing effort was clearly
using the term "standards". They stopped using that term after they
were shouted down at KR'91. But the people who shouted them down were
not the people with the problems, but the people who were afraid that
their own pet solutions would be left out.
The PDES and IRDS groups have some very pressing problems, and they
desperately want standards. If the people who happen to know something
about knowledge representation don't offer them anything better, they
will adopt some very ugly, ad hoc proposals and force them on all of us
as standards. If that happens, the KR community can pass any resolutions
they like, but they would all be totally irrelevant.
