Abstract

The need for semantic processing of information and services has lead to the introduction of tools for the description and management of knowledge within organizations, such as RDF, OWL, and SPARQL. However, semantic applications may have to access data from diverse sources across the network. Thus, SPARQL queries may have to be submitted and evaluated against existing XML or relational databases, and the results transferred back to be assembled for further processing. In this paper we describe the SPARQL2XQuery framework, which translates the SPARQL queries to semantically equivalent XQuery queries for accessing XML databases from the Semantic Web environment.
