Integrated multimedia object and application modelling based on events and scenarios

An important issue in multimedia information systems is the lack of an integrated model for complete representation of the multimedia objects and applications. We present an object oriented database model that aims at representation of multimedia objects and applications. The application representation is based on composition (spatial and temporal) modelling and scenario modelling. An important feature of the proposed model is that there is an integrated modelling of the multimedia objects as well as of the applications that utilise them in a uniform way. Moreover the mappings between the two categories of classes are defined.
