Architecture for client-independent Web-based applications

The development effort for interactive Web applications is continuously increasing, because multiple clients with widely varying user interface (UI) capabilities have to be supported. In addition, personalization features render the task more complex. The MUSA (Multiple User Interfaces, Single Application) system addresses that issue by decoupling the application logic from the UI logic. The architecture of the MUSA system is based on an event-graph. The event-graph abstracts UI issues and personalization issues from the implementation of the application. The paper presents the architecture of the MUSA system and introduces the event graph and the set of events used.
