I think we agree.    (02)

Certainly.    (04)

Every aspect of a sign can be classified as a mark/token/type.  But
the number of different kinds of signs is enormous.  Every input from
every sense is a sign, and the number of different kinds is as large
as all the kinds of sensory inputs we might have.    (05)

Then the process of interpreting a sign (called semiosis) produces
one or more new signs -- and those can be classified in a huge number
of different ways.    (06)

Yes, indeed.  The Cyc ontology is the largest formal ontology
available, and it is always worthwhile to consider what they did.    (08)

Peirce's analysis is not a replacement for Cyc (or any other ontology).
It is a complementary way of looking at things that can frequently
clarify and resolve many puzzling issues.    (09)
