Extending XQuery for Semantic Web Reasoning

Abstract. In this paper we investigate an extension of the XQuery language for querying and reasoning with OWL-style ontologies. The proposed extension incorporates new primitives (i.e. boolean operators) in XQuery for the querying and reasoning with OWL-style triples in such a way that XQuery can be used as query language for the Semantic Web. In addition, we propose a Prolog-based implementation of the extension

Querying and reasoning with RDF(S)/OWL in XQuery

Abstract. In this paper we investigate how to use the XQuery language for querying and reasoning with RDF(S)/OWL-style ontologies. Our proposal allows the handling of RDF(S)/OWL triples by means of a XQuery library for the Semantic Web, and it encodes RDF(S)/OWL reasoning by means of XQuery functions. We have tested and implemented the approach

Growing XQuery

XML [39] is a flexible format that can represent many classes of data: structured documents with large fragments of marked-up text; homogeneous records such as those in relational databases; and heterogeneous records with varied structure and content such as those in object-oriented and hierarchical databases
