ACTION-32 http://www.w3.org/2009/sparql/track/actions/32 To revive the discussion on negation, I would like to point you to the overview of options for implementation at: http://www.w3.org/2009/sparql/wiki/Design:Negation In particular, binary operators vs. FILTER expressions, and set based MINUS in SeRQL vs UNSAID are discussed. Note that MINUS in SeRQL != MINUS in Mulgara (?), which has the same semantics as UNSAID.
