immaterial parts and MaterialEntity about bfo HOT 8 CLOSED

"Calling the parent of these three MaterialEntity does make it sound as if they don't include the immaterial
parts."

I think the whole of a MaterialEntity must have material parts, so it's not that problematic to keep the same.
We don't assert anywhere that all parts of material entities are material entities.

I don't know if Sites are intended to be a subtype of immaterial entity. I thought it should be considered a
synonym, but if Barry disagrees then we need to add immaterial entity as a parent to it.

True. I think it would help to say explicitly that holes, which are immaterial, are
allowed to be parts of material entities. My sense is that, in this sort of case,
people don't trust their intuition that holes are actually there and are countable,
causes things, and so forth.

(Sites are partly material as well as immaterial, or at least they were when I last
looked.)

Best wishes,
Colin.

Agreed on documentation. Regarding sites, I have conflicting information from conversations with Barry. Needs
to be clarified.

Colin, can you verify that the current BFO 2 inclusion of 'immaterial entity' and corresponding axiomatization solves this issue?

OK, happy that this allows us to have immaterial parts that aren't necessarily sites.
