Add to ORKGIn this paper we investigate an extension of XQuery for querying (and inferring) from RDF documents. Following a graph based approach for specifying queries against RDF, XQuery is extended with construction of answers and boolean predicates for RDF entailment relationship inference. We will also study how to implement it in logic programming by using logic rules for executing RDF/XQuery queries
