Hi Alan & Zille

I suspect my ontologies are very similar to Alan's,
but I use terminology that is a little more like ordinary English.
(see http://mKRmKE.org)

compare
    process has_participant continuant
to
    entity do action done;

process <=> action
continuant <=> entity

actions can have modifying phrases which specify time, object, etc.

I plan to read your references carefully,
but first I have to finish my jury duty.
I'll get back to you soon.

Dick
