Mapping XML to OWL Ontologies Hannes Bohring * and S¨oren Auer+

Abstract: By now, XML has reached a wide acceptance as data exchange format in E-Business. An efficient collaboration between different participants in E-Business thus, is only possible, when business partners agree on a common syntax and have a common understanding of the basic concepts in the domain. XML covers the syntactic level, but lacks support for efficient sharing of conceptualizations. The Web Ontology Language (OWL [Bec04]) in turn supports the representation of domain knowledge using classes, properties and instances for the use in a distributed environment as the World Wide Web. We present in this paper a mapping between the data model elements of XML and OWL. We give account about its implementation within a ready-to-use XSLT framework, as well as its evaluation for common use cases.
