State-of-the-art Web applications include both navigational elements and business processes, but most Web application design methods treat business processes as just another kind of navigation. The authors' extensions to the object-oriented hypermedia design method (OOHDM) aim to remedy this situation. Rather than using navigation to emulate business processes, their new mechanisms allow developers to specify and implement processes explicitly by dealing with activity semantics and states. We describe proposed extensions to OOHDM and explore their use at an online retail store.
