The past decade of research on open hypermedia systems has resulted in a number of experiences and results that can benefit current and future World Wide Web development. Based on a description of the HyperDisco open hypermedia system, this paper presents five open hypermedia lessons learned that can serve as examples of new types of services in future versions of the World Wide Web. The paper ...

We believe that workflow services can be implemented using the OHS approach and such an open hypermedia based workflow service will be more flexible to fit into dynamic work situations than other approaches to provide WF functionality. The on-going OHS work on a component-based architecture and an extensible open hypermedia data model provides a foundation for developing such hypermedia based W...

It has to provide hypermedia-document access methods. Finally, it has to allow the exchange of hypermedia documents with other systems. On a technical level, an obj...
