relevant paper on using OWL (description logics) for RDF validation

I suggested that anyone who is going to present technical stuff at the WF F2F 
meeting next week send out something about the stuff beforehand.

I am here covering my marker.  (In a certain sense - this is an academic 
paper, not a manual, although this stuff is actually implemented in Stardog 
ICV, more or less.)

Questions welcome.
