Mike, I haven't found partitions along those lines to be useful. There are
disjoint categories such as "Event" and "Object" and "AttributeValue" to
which I can give some necessary conditions. But in trying to represent the
basic elements of thought, which are reflected in the basic language, there
are too many ways of viewing things to make it practical to try to squeeze
all those views into a few top partitions. Roles, for example, can cut
across several disjoint categories.  (02)
If you have some specific logical properties that you think should be
assigned to those top-level categories, send me a note and I will be happy
to see how they can be related to the COSMO elements.  (03)
There is a lot of work already done in the OpenCyc, SUMO, DOLCE, BFO,
ISO15926, and other ontologies that can serve as a starting point if one
wants to redo the top-level categories. Seeing how these can be related to
each other is quite educational.  (04)
