Updates in RDF stores have recently been standardized in the SPARQL 1.1 Update specification. However, computing answers entailed by ontologies in triple stores is usually treated orthogonal to updates. Even SPARQL 1.1 Update language and SPARQL 1.1 Entailment Regimes specifications explicitly exclude a standard behavior about how SPARQL endpoints should treat entailment regimes other than simple entailment in the context of updates. In this paper, the authors take a first step to close this gap by discussing possible semantics along with potential strategies for implementing them.
