Hi Mike (01)
I'm glad to hear those distinctions work so well for you. (02)
Sometimes, they are not so clear to me.
And I wonder why does it matter
whether a contract, for example,
is continuant or occurrent,
physical or abstract,
independent or relative or mediating?
I focus on actions and interactions. (03)
I do wonder about two things.
(1) Do you apply all three distinctions together?
If so, you end up with only 12 subclasses of Thing,
and I would view all the other intermediate classes
as unused "clutter".
(2) When you add whole/part, set, time and so on --
how does that affect the ease of use? (04)
