Until now, the SPARQL query language was restricted to simple entailment. Now SPARQL is being extended with more expressive entailment regimes. This allows querying over inferred, implicit knowledge. However, in this case the SPARQL endpoint provider decides which inference rules are used for its entailment regimes. In this paper, the authors propose an extension to the SPARQL query language to support remote reasoning, in which the data consumer can de ne the inference rules. It will supplement the supported entailment regimes of the SPARQL endpoint provider with an additional reasoning step using the inference rules defined by the data consumer.
