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.

Cheers,
Simon
