Translating XPath Queries into SPARQL Queries
Abstract The W3C has developed XPath [3] as a query language for XML data. XPath is embedded in many other languages like XQuery and XSLT. The name of XPath derives from its basic concept, the path expression, with which the user can hierarchically address the nodes of the XML data. The user of XPath may not only use simple relationships like parent-child, but also more complex relationships like the descendant relationship, which is the transitive closure of the parent-child relationship. Furthermore, complex filter expressions are allowed in XPath queries. RDF is a language for representing information about resources in the World Wide Web. SPARQL [2] supports querying RDF by triple and optional patterns, con- and disjunctions and extensible value testing. <bookstore> <book category="CHILDREN"> <title>Harry Potter</title> <author>J. K.
