SPARQL/Extensions/Entailment Regimes

From W3C Wiki

The SPARQL specification is defined for matching graph patterns based on simple entailment, but does discuss extending SPARQL basic graph pattern matching to other entailment relations.

There is a SparqlOwl Google code project that contains a short bibliography of links to other material related to integrating OWL entailments into SPARQL.

Evren Sirin and Bijan Parsia proposed SPARQL-DL for bringing OWL-DL reasoning to SPARQL basic graph patterns. The Clark & Parsia blog contains a number of entries about evaluating SPARQL-DL queries.

Axel Polleres has expressed interest in discussing SPARQL for higher entailment regimes in a January 2008 message to public-rdf-dawg-comments.
