(Composite, or compound Functional properties are cool too ;))

I don't know about the BPSW work, but there's an OWLED task force:
	<http://code.google.com/p/owl1-1/wiki/DatabasEsque>
that is working on an "easy keys" proposal:
	<http://code.google.com/p/owl1-1/wiki/EasyKeyProposal>

which most likely will include compound keys. It has the start of a  
discussion.

You might find this paper:
	<http://webont.org/owled/2007/PapersPDF/paper_19.pdf>
interesting as well. (The terminology is a bit different, but where  
you see "identification" think "keys".) Turns out, perhaps  
unsurprisingly, that DL-Lite_a plus compound keys is still database  
reducible.

Cheers,
Bijan.
