Rinke - FWIW, there is some versioning terminology in OWL 1.0 --  
whatever we do with respect to both import and versioning, we do have  
the responsibility to figure out what to do about those and to  
appropriately update - esp. if we do anything non-backwards compatible.
  btw, with respect to the import discussion, I would point out that  
this will have a very large impact if we are not backwards compatible  
(several of the large deployed ontologies, esp. in the govt sector,   
are managed as somewhat separate pieces with a main ontology that  
imports those pieces) , so we should be sure we are careful to  
document any changes and if the old mechanism is changed, to provide  
a well documented "fix"
p.s. Please note, none of this meant to in any way comment on the  
imports issue - I never liked the old one anyway.
