Len,
I definitely agree, and wish you good luck :-) (01)
prior attempts to do similar things have generated
very interesting and long discussions......but never ended up in any
usable agreement (02)
I think when trying to define the word 'ontology' people have been
discussing for years, and generated over twenty valid definitions, and
still struggle to put their points accross precisely, as each
definition can be
interpreted differently by different people who place it in different
context (relating to different axioms) (03)
I think it may be also agree that a definition should not be longer
than a sentence or a phrase or two at the most, and, that more than
one definitions is possible, as long as whoever uses the term (we had
a long discussion about the meaning of 'term' two years back)
specifies what meaning they are referencing. (04)
Kind of really representative issuesf the challenges that ontology
engineering faces (05)
Despite the lack of results so far, however, it has been extremely
entertaining and educational (06)
Opening a glossary page on the wiki could be like opening another
pandora's box, but hay
thats the name of the game I guess (07)
