Abstract: The wide use of a number of cultural heritage metadata schemas
imposes the development of
new interoperability techniques that facilitate
unified access to cultural resources. In this paper, we focus on the ontology
based semantic integration by proposing an expressive mapping language for the
specification of the mappings between the XML-based metadata schemas and the
CIDOC CRM ontology.
We also present an algorithm
for the transformation of XPath queries posed on XML-based metadata into
equivalent queries on the CIDOC CRM ontology.
Keywords: Metadata interoperability, semantic integration, query
transformation, mapping languages, metadata schemas.
