I personally don't have a particular preference of teleconference or mailing
list, but (for the record), of the features listed above, the following are
important for the Cleveland Clinic and the way we use SPARQL and is primary
motivation for our joining the WG (so we hope the group strongly considers

- Control of inference

Generally, it would be a shame if we didn't seriously consider a way to
specify entailment regimes given the mature state of the various standards
on RDF entailment: OWL, OWL2, and now RIF

- AllNamedGraphs

I hope the case has been made by the usecase and feature description

- BlankNodeRefs

Ditto (i.e., the feature description should already have sufficiently made
the case for the value of this: multiple, implementation-specific
implementations,e tc..)
