This paper describes the extension of the Semantic Web query language SPARQL by defining the semantics of SPARQL queries under the entailment regimes of RDF, RDFS, and OWL. It reviews the conditions that SPARQL
imposes on such extensions, discusses the practical difficulties of this task, and explicates the design choices underlying our proposals. In addition, it includes an overview of current implementations and their underlying techniques.
