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 orthogonal to updates. Even the W3C's
recent SPARQL 1.1 Update language and SPARQL 1.1 Entailment Regimes specifications
explicitly exclude a standard behaviour how SPARQL endpoints should
treat 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 corresponding to (the RDFS fragment of) DL-Lite 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. We treat both, (i) materialised RDF stores, which store all
entailed triples explicitly, and (ii) reduced RDF Stores, that is, redundancy-free
RDF stores that do not store any RDF triples (corresponding to DL-Lite ABox
statements) entailed by others already.
