[ontolog-forum] Enterprise Model Patterns.

["David C. Hay" <dch@xxxxxxxxxxxxxxxxxxxxxxx>]

OK, I went into your description of Cyc in a bit more
detail, and I fear I must disagree on one point. I apologize for having
been so careless. 

Apparently Cyc puts this constraint on a Geographic Location:

> In all cases the region in
> question must contain some tangible component
> with which it is possible to make physical contact. The instances of
> GeographicalRegion contrast in this respect with the instances of
> GeographicalThing-Intangible, which are wholly intangible.

Why would they do that?  To combine the tangibleness of a geographic
location with the definition of it clogs the definitions.  It is
not  in (as we data types call it) even first normal form.

I guess I was wrong in the previous note.  My Geographic
Location would be a "Geographical
Thing-Intangible."  I have no reason to describe a
"Geographical Thing-Tangible".
