The Open Hypermedia model is based upon the separation of hypertext links from documents, treating them as separate, first class entities. Distributed link services take this approach a stage further, with separate link services providing and managing the links. In this paper, we describe the development of a system infrastructure for link services using the Web Services architecture. More precisely, we target the development of Web Services composition to enable integration and coordination between link services. A second prototype illustrates the use of Semantic Web technologies to implement a simple open hypermedia system. We discuss the role of Semantic Web technologies in the service-oriented approach to open hypermedia systems.
