Hi Duane,    (01)

You said: > it is about the N to N relationships that exist between 
those elements??      (02)

Could expand on these "N to N" ideas a little?
Are the N-Ary ideas of Natasha Noy and Alan Rector relevant?    (03)

(Background: Rex Brooks, Peter Yim, myself, and several others are
considering the "Health Informatics Standards Landscape" and the complex
relationships may be better described initially with graphs rather than a
spreadsheet)    (05)

Cheers,    (06)

Bob      (07)

DN - would it be fair to extend this to also state that the ontology is 
also about the relationships between the elements of a taxonomy in 
addition to the hierarchal nature of their associations?  An ontology is 
about more that just the elements of a taxonomy and their individual 
semantics - it is about the N to N relationships that exist between 
those elements??  Could one infer that Taxonomies are always scoped to 
only represent hierarchal relationships between elements?  I see a lot 
of people who seem to infer this but have never seen it written in black 
and white.    (011)
