OWL 2 Axiom Annotations (or to a lesser extent RDF reification) provide the necessary means to do add meta information, but do not have a very nice RDF encoding (which is a significant problem in very large knowledge bases). Thinking about (optional) statement identifiers or similar concepts for RDF 2 would be very welcome. Kind regards, Jens -- Dipl. Inf.
