This document discusses using XSPARQL for data integration and transformation between different data formats like RDB, XML, and RDF. It describes how XSPARQL extends the syntax of XQuery to allow querying and transforming data between these formats using a single language. Examples are provided of using XSPARQL to extract data from an XML file and generate RDF, and to integrate data from an XML file with data from a BridgeDB link database.
