In this paper we describe a framework for exploiting the semantics of Webservices through UDDI registries. As a part of this framework, we extend theDAML-S upper ontology to describe the functionality we find essential fore-businesses. This functionality includes relating the services with electroniccatalogs, describing the complementary services and finding services accordingto the properties of products or services. Once the semantics is defined, thereis a need for a mechanism in the service registry to relate it with the serviceadvertised. The ontology model developed is general enough to be used with anyservice registry. However when it comes to relating the semantics with servicesadvertised, the capabilities provided by the registry effects how this isachieved. We demonstrate how to integrate the described service semantics toUDDI registries.
