XSD To OWL: A Case Study

This paper addresses the challenge of applying Semantic Web technologies like OWL-DL reasoners to XML documents to find implied relationships not stated directly in the documents. The challenge comes because the structure of XML schema often contains implicit assumptions about taxonomy and relationships. This makes it difficult to implement a completely general and automated mechanism to transform XML schemas to OWL ontologies. We describe our efforts to transform XML schemas to OWL ontologies and discuss our rationale for particular mappings. This work contributes to this area of research by providing new interpretations of XSD terminology in the context of OWL and shows how to map XSD structures to more complex OWL structures.
