WWW is currently undergoing a remarkable change from a collection of pages to a collection of services that interoperate through the Internet. The representative types of these services are XML Web Services and ebXML, which are emerging as significant e-Business application frameworks. Both ebXML and Web Services, however, use different registries for publishing and discovery of services, and this has given rise to some problems when adopting frameworks. Furthermore, these registries support only keyword-based search, which does not make use of semantic information, and which does not address the problem of matching service capabilities and allowing service location based on the functionalities sought. This paper shows that service descriptions in OWL-S can be mapped into UDDI and ebXML registry entries, and can be migrated from registries; therefore, it provides not only a way to integrate registry entries but also a way to build the foundation of semantic service discovery. Also, migrated OWL-S can be updated periodically while registry entries are being modified.
