Hi Enrico,

Are there existing implementations of SPARQL that incorporate OWL Direct 
Semantics in the manner you're proposing?

Bijan, Birte -- do the systems that you're familiar with currently 
implement SPARQL with OWL Direct Semantics in the manner that's in the 
current entailment document, or is it not yet implemented at all?

thanks,
Lee
