Jim, I know it seems like overkill on the
smallest semantic detail, but in my experience when it comes to abtract data
models, this is where the war can be won or lost.
I also wanted to document the decision so when
the next Higgins newbie asks what we mean by “Entity” we have a
clear answer.

The table Paul sent yesterday made me realize there's a different way to
think about our usage of the word "entity" in the Higgins data model
(one
that aligns with what I think Tony and Mike have been saying).
The realization was that a pure Higgins Entity -- a single raw node in the
Higgins Global Graph -- is not actually a Resource because, until you add at
least one Attribute, it is not even identifiable (which is a requirement of
an Identity -- ITU definition -- or a Resource -- IETF/W3C RFC 3986
definition).
In other words, if the label "Entity" simply refers to a graph node
representing the pure concept of Entity, then it does not become any form of
"representation" of the Entity until you begin adding Attributes that
turn
an Entity into an Identity. (That explains why Entity and Node seem so
interchangeable.)
If we take this approach, it eliminates the conflict with either the ITU or
IDGang. The table looks like this:
