A Semantic Mapping Approach for Transforming DTD into RDFS/OWL

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.
