The SPARQL2XQuery Framework bridges the gap and creates an interoperable
environment between the Web of Linked Data (OWL/RDF/SPARQL) and the
XML (XML Schema/XML/XQuery) worlds. Using the SPARQL2XQuery
Framework, XML datasets can be turned into SPARQL endpoints.

The SPARQL2XQuery Framework provides a generic method for SPARQL to
XQuery translation, with respect to a set of predefined mappings between
ontologies and XML Schemas.

Particularly, the SPARQL2XQuery Framework provides mechanisms for:
(a) ''Query translation'' (SPARQL to XQuery) (b) ''Mapping specification & generation'' (Ontology to XML Schema)
and (c) ''Schema transformation''
(XML Schema to OWL).

===Key Features===

This SPARQL2XQuery Framework is an essential component in the Web of Linked Data that allows setting SPARQL endpoints over the existing XML data, as well as a fundamental part of ontology-based integration frameworks involving XML data sources.

* '''Schema Transformation.''' XML Schemas are transformed to OWL ontologies using the XS2OWL module.
 
* '''Mapping Generation.''' The mappings between the XML Schemas and their OWL representations can be automatically detected and stored as XML documents.

* '''Mappings Specification'''. Mappings between OWL-RDF/S ontologies and XML Schemas can be manually specified and used in the SPARQL to XQuery translation.

* '''Query Translation.''' SPARQL to XQuery Translation: SPARQL queries that are posed over ontologies (RDF/S - OWL), are translated into an XQuery queries that can be answered from the XML data.
 
*'''Query Results Transformation.''' The query results are transformed in either SPARQL Query Result XML Format or in RDF format.

*'''XML - RDF Transformation.'''Transformation of XML data in RDF and vice versa.
