Optimising XML-RDF Data Integration
Published in: Extended Semantic Web Conference

Abstract
The Semantic Web provides a wealth of open data in RDF format. XML remains a widespread format for data exchange. When combining data of these two formats several problems arise due to representational incompatibilities. The query language XSPARQL, which is built by combining XQuery and SPARQL, addresses some of these problems. However the evaluation of complex XSPARQL queries by a naive implementation shows slow response times. Establishing an integrated formal model for a core fragment of XSPARQL will allow us to improve performance of query answering by defining query equivalences.
