Sure that quality applications must be well thought and described before the development phase and that a design methodology can be much more than a help in most occasions, we propose a development framework based on a well organized and tested design methodology for hypermedia applications. In this paper we show its in-the-large structure and explain which modules complete it and how they interact and communicate. We also describe the solution we chose to store and share data and information within the framework itself. Exploiting an ontological vision (preserving the semantic aspects) we hope we will get better results than using a more conventional XML solution. KEYWORDS Ontologies, Conceptual models, W2000, RDF, Web applications.
