Re: OWL vs RDF

Thanks for the info, Robert.

No problemo - we're all working with between 10 - 25% of the  
resources we really need to get to all the various tasks that need to  
be done in a timely manner.

I just keep mentioning this issue as a "gentle" prod, because I found  
the ProtegeOWL tutorial immensely helpful when I read quite a while  
back and think it should probably be REQUIRED reading for everyone  
both using ProtegeOWL and expecting to have at least a general  
understanding of how to make best use OWL's expressivity.

Having the OWL v1.1 & Data Property issues taken into account in that  
tutorial would be extremely useful.

Cheers,
Bill
