SUO: Re: CG: Physical and Abstract (was Lifecycle Integration Schema
Radu,
I was not pretending to define the English words
"abstract" and "abstraction". I was merely giving
criteria that a knowledge engineer can use to
classify terms in the artificial categories
that I have named P and A. As I said in my KR
book, P and A are the official names, but I
commonly use the labels Physical and Abstract
to make them easier to remember.

I believe that any two trained knowledge engineers
would be able to make the same classifications
according to the criteria I gave.
And I repeat that the categories P and A are
artificial terms with fixed criteria for their
use. They should not be considered synonyms
for the English words, which do indeed evolve
over time.
