From Chapter 7

Query Languages

of Foundations of Semantic Web Technologies:

In this chapter, we have a closer look at some important query languages for RDF and OWL. For RDF, this query language is SPARQL, while for OWL DL we have to be content with so-called conjunctive queries as a basic formalism that is not part of a standardized query language yet. We will see that the latter is also closely related to the kind of rules introduced in Chapter 6.
