Hi Alan & Zille

I'm back from jury duty, and
I read Smith's "Beyond Concepts" paper, and
I skimmed through the basic ontology.

As I understand "Realism", I agree with the philosophy.
I was introduced to this philosophy by
Ayn Rand's "Introduction to Objectivist Epistemology".
I consider her discussion of concepts to be outstanding.
However, she barely touches on the subject of "actions".

In my terminology, "processes" are either
"actions" -- single entity, or
"interactions" -- multiple entities.
I barely touch on the subject of "interactions".

If you want to get a feel for my ontologies,
I suggest that you look at
    http://mKRmKE.org/kb/spo.mkr.html
    http://mKRmKE.org/kb/tabrasa.html
    http://mKRmKE.org/kb/tabrasa.def

You will need some understanding of
my Knowledge Representation language, mKR,
to read these ontologies.  I suggest looking at
    http://mKRmKE.org/doc/MKRintro.html
Note that mKR has extensive features for describing
context, definitions, actions, methods, n-ary relations.

My Knowledge Explorer, mKE, has built-in features
for interfacing with OpenCyc, OWL, RDF.

Dick
