Mike - that's easy - there's the semantics document the Webbies  
preferred and the one the formal KR folks preferred - can you guess  
which is which?

Seriously, the real answer is that these were developed in tandem, the  
axiomatic one under DARPA support.  When we moved to the W3C, there  
wasn't anyone who wanted to update the axiomatic (KIF) version and we  
decided to have only one - since more people on the committee liked  
model theory, that's the way we went.

p.s. also, interestingly, there were divergences between the two - I  
forget the details - it would be a good piece of work to bring the  
rule-based one up to snuff with OWL 1.0 or 1.1...
