Managing Co-reference (Was: A Semantic Elephant?)

One more public thread on SW list on our favourite issue. But some interesting points to note in the current discussion, well summed up by Aldo Gangemi at mid-course.

• We definitely need some property or mechanism, weaker as owl:sameAs, to assert that two URIs have similar referents.
  
• The semiotic aspects of co-reference are more and more acknowledged, even by formal logic gurus.

Hopefully this thread will eventually have some follow-up on some standardization track.
