A Process Environment Supporting Web Multimedia Information Systems

The Web is widely considered as a reliable and promising approach to design new information systems in various application areas such as geographical information systems. A flexible and interactive control of user actions and interactions must be implemented to ensure system consistency and make its evolution easier. The Web environment does not provide such a control. Combining both works from the process domain and those from multimedia community, we propose a Temporal Process Model allowing the activities specification and the expression of their organization via temporal scenarios. Our approach leads to a new environment where processes could be executed in a safe and sound environment. The paper presents the process model and the object oriented framework we developed and emphasizes the application of our approach to an existing Multimedia Information System dedicated to natural hazards.
