Abstract. While the “Universal Description, Discovery and Integration” (UDDI) service registry standard has drawn great attention by the research community, it has not been widely adopted by the software industry. Objections towards UDDI include technical as well as conceptional arguments. Being an official ISO standard and providing a number of features UDDI is missing, “Electronic Business using Extensible Markup Language ” (ebXML) Registry could be an adequate alternative for the implementation of service registries and/or repositories. However, little work has been done regarding the integration of Semantic Web Services (SWS) into ebXML Registry. In this paper, we present a solution extending the ebXML Registry by capabilities to handle and provide SWS. This includes a concept for the integration of SWS into ebXML Registry as well as a prototypical implementation using SAWSDL and the open source framework freebXML.
