Construction et manipulation de présentations spatio-temporelles multimédias à partir de serveurs d'objets répartis : applications aux données sur le Web

Abstract : We propose an infrastructure (JAGUAR) for specifying spatio-temporal multimedia presentations managers. These managers are mediators between applications and distributed heterogeneous object sources accessible through the Web (via their URL). A manager is able to define, query, and build presentations that are stored in a multimedia database system. All objects are described by a schema that associates a default presentation to each of them. We defined a spatio-temporal model to integrate objects and presentations. The model describes objects composition through spatio-temporal relations. We also proposed OQLiST a language that provides spatio-temporal operators. Language and model can be used for specifying, querying and representing homogeneously inter and intra-media descriptions. In order to validate the JAGUAR infrastructure, a presentation manager prototype was implemented using SMIL and Java Media Framework (JMF) platforms. The manager has been used for specifying and implementing (1) a touristic application and (2) a visualization tool for objects stored in a data warehouse. For the later, the manager provides a specific schema for the data cube.
