document: Using OWL for querying an XML\/RDF syntax Some recent initiatives try to take profit from RDF to make XML documents interoperate at the semantic level . Ontologies are used to establish semantic connections among XML languages , and some mechanisms have been defined to query them with natural XML query languages like XPath and XML Query . Generally structure-mapping approaches define a simple translation between trivial XPath expressions and some RDF query language like RDQL ; however some XPath constructs can not be covered in a structure-mapping strategy . In contrast , our work takes the model-mapping approach , respectful with node order , that allows mapping all XPath axis . The obtained XPath implementation has the properties of schema-awareness and IDREF-awareness , so it can be used to exploit inheritance hierarchies defined in one or more XML schemas .
