[Person-ontology] Fwd: OWL for exchanging ontologies

[paola.dimaio at gmail.com]

Pat and all

me too - I want to learn everything about clif/kif/ikf and the lot - so look
forward to be hearing more

But before talking 'encoding' (owl not owl) there is a lot of other homework
to be done

Apologies if I am joining this discussion late, and I may have missed
something already discussed

do you have pointers to project documentation /conclusions on goals,
boundaries,  entities, relations, axioms, vocabularies, requirements, an
analysis and comparison with existing ontologies etc

I think the choice of representation should be done later, then Pat will be
able to to best advise from there, perhaps

Look forward to be learning more
cheers
