Slides covering the following topics: SPARQL can now be used with RDF Schema, OWL, and RIF semantics. Entailment Regimes overwrite evaluation of basic graph patterns. Property Paths from SPARQL Query 1.1 can be problematic. Definition of solutions (relatively) general: a) work for sub-graph matching/simple entailment and b) OWL’s Direct Semantics needs extra conditions/definitions. Implementation and efficiency for OWL can be problematic – necessitates OWL 2 Profiles.
