The Data Access Working Group has asked me to ask participants in
SWBPD to comment on two of their open issues.  The DAWG chair is
concerned that these issues are currently causing their schedule
to slip and asks for opinions on whether these issues need to be
resolved in a version 1 SPARQL specification.

Both of these open SPARQL issues are related to data provenance.

Specifically, if any of you have user feedback or design experience
to comment on the short-term need for and whether you believe the
community has suffcient design experience to believe that DAWG
should attempt to settle the following two issues, please send
your thoughts to public-rdf-dawg@w3.org or to

Allowing query expressions to refer to the source of a triple.

NOT is not a good choice for "absent from graph": "UNSAID", unasserted, log:notIncludes
