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.
