There are currently two language features in OWL-1.1 where RDF reification is used in the RDF syntax: * axiom annotations (comments on ontology axioms) * negative property assertions (negated statements, i.e. "NOT(s p o)") And two issues have been raised, one for each of these language features: * ISSUE-67: use of reification in mapping rules is unwise (axiom annotation) <http://www.w3.org/2007/OWL/tracker/issues/67> * ISSUE-81: reification unwise in negative property assertions <http://www.w3.org/2007/OWL/tracker/issues/81> So the OWL-WG *will* address all the OWL-1.1 related problems resulting from RDF Reification.
