I agree that the various ontologies for time constitute an excellent
test case for people doing research on ontology mapping.

But it seemed to me that the widespread use of DAML out in the world
would be promoted by the existence of a number of very useful,
comprehensive but clean ontologies that represent some measure of
consensus.  DAML-S is one such effort.  Time could be another.

I think there is probably an optimal level of coordination that is
somewhere between individual research sites and global
standardization, and that a DAML community-wide effort might be
something worth aiming for.  That wouldn't preclude alternative
ontologies for particular uses.

To daml-all: Please excuse the extra email.  I expect to move it onto a
special interest group mailing list as soon as we get all the
expressions of interest.
