Abstract:
XML (eXtensible Markup Language) and its
schema language are becoming a primary data
exchange format on the current web. In the next
generation of the Semantic Web, the drawbacks of
XML and its schema are appeared. Most data on the
Web, however, is in the XML format, but using XML
requires applications to understand the format of
each data source that they access. To achieve the
benefits of the Semantic Web involves transforming
XML into the Semantic Web language, RDFS/OWL, a
process that generally has manual or only semiautomatic
components. This paper proposes a set of
rules to map DTD to RDFS ontology. This approach
mainly considers the constraints of DTD to map
RDFS/OWL. Constraints are a fundamental part of
the semantics of the data. So, this approach is to
ensure the integrity of the structure and provide more
meaning for the original DTD while transforming
them into RDF Schema.
