English abstract:
Updates in RDF stores have recently been standardised in the
SPARQL 1.1 Update specification. However, computing answers entailed by
ontologies in triple stores is usually treated orthogonally to updates. Even W3Cīs
SPARQL 1.1 Update language and SPARQL 1.1 Entailment Regimes specifica-
tions explicitly exclude a standard behaviour for entailment regimes other than
simple entailment in the context of updates. In this paper, we take a first step
to close this gap. We define a fragment of SPARQL basic graph patterns corre-
sponding to (the RDFS fragment of)
and the corresponding SPARQL
update language, dealing with updates both of ABox and of TBox statements. We
discuss possible semantics along with potential strategies for implementing them.
Particularly, we treat materialised RDF stores, which store all entailed triples
explicitly, and preservation of materialisation upon ABox and TBox updates.
