Abstract: The paper presents a methodology for developing multimedia information systems. These latter are considerably different from the traditional ones because they deal with very complex and heterogeneous data such as sound, still image, text and video. The complexity of data is principally due to their dependency on time. During their presentation, multimedia data must be synchronized on both temporal and spatial scales. The paper defines a conceptual object model and gives an outline of a design methodology. The presented model is a combination of object oriented concepts and Allen's relations. In order to make the designer task easier and to help him during the development of his model, the model has been based on existing formalisms, such as those offered by OMT. The defined method is based on the object specification, and a number of models that are designed during the development process according to the waterfall approach.

Keywords: ECA rules, Petri nets, multimedia information systems, spatio-temporal relations, waterfall approach.
