SPARQL 1.1 was recently released, which includes entailment regimes for
RDFS and OWL vocabularies and a mechanism to express navigation patterns through regular expressions. Unfortunately, there are still some useful navigation patterns that cannot be expressed in SPARQL 1.1, and the language lacks of a general mechanism to express recursive queries. To the best of the authors' knowledge, there is no RDF query language that combines the above functionalities, and which can also be evaluated efficiently. It is the aim of this work to fill this gap.
