Blimey...didn't think I'd be spending all morning dealing with this. (01)
Ed, I doubt there'll be any ISO problems, 'cos IDEAS isn't an ISO standard.
It's a standard being developed by the Australian, Canadian, Swedish, UK and
US departments of defence. The only bit we've put in the public domain so
far is the foundation...what Rich is calling a UHLO (catchy!). The website
is at www.ideasgroup.org (02)
As for whole-part, it's pretty simple really. It means one individual is
entirely within the extent of the other. Doesn't matter what the spatio
temporal extent of the whole is, so long as the part is within it. There's a
whole section on this in Chris's book. There are lots of specialisations of
whole-part for lots of different applications, but there's no need for all
that in a foundation ontology, I think. (03)

Does anyone know what wholePart means? (06)
As I recall, some published paper on Whole-Part relationships identified
22 possible axioms (although many of them require a 4D universe to have
meaning). So wholePart is a category of relations that have exactly
which axioms in common? Are they all antisymmetric? are they all
transitive? are they 'perdurant'? Etc. (07)
I don't doubt that the specification at least tries to define these
things carefully. I do doubt that its definitions are axiomatic. But
we are ill-advised to judge anything from a list of indented terms. (08)
(And Ian must be careful how much he publishes to this group, because
such publication has the potential for violation of ISO copyright.) (09)
