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.    (02)
