Description: This paper proposes a methodology for hypermedia design which is based on a UML profile for the hypermedia domain. Starting with a use case analysis and a conceptual model of the application this paper first provides guidelines for modeling the navigation space. From the navigation space model, in a next step, a navigational structure model can be derived which shows how to navigate through the navigation space using access elements like indexes, guided tours, queries and menus. Finally, a presentation model is constructed that can be directly implemented by HTML frames. Author(s) : Rolf Hennicker and Nora Koch
