Re: [ontolog-forum] A "common basis"

["Gary Berg-Cross" <gary.berg-cross@xxxxxxxx>]

Perhaps the presenters of this idea (a single ontology  was a prerequisite to success) were focused on a Domain model where they felt they had the basic scope, foundationa terms, set or relationships well in hand.  Of course this is also wrong but on a lesser scale.  Sometimes people are thinking, this ontology defines everthing I need for the meaning of this DB.  In that sense the ontology is serving as a scoped concept model for the DB as "reality".

Holy smoke!  The last 20 years would suggest it's the other way 
round:  It is (perhaps) possible to have a common basis for mapping 
between multiple ontologies, but it is a (really) difficult problem!  
What did this guy have in mind as a "common basis"?  If all the 
speaker meant was some sort of overarching reference model in well-
circumscribed domain, then ok.  But it sounds like he or she had 
something more comprehensive in mind.
