Temporal and interactive relations in a multimedia database system

We present an approach for temporal and interactive relation composition of media. The approach is based on time-interval and dependency temporal relations. We consider the seven relations of Allen (equals, meets, finishes, starts, before, overlaps, during) with the following features. Firstly, the temporal relations are designed to specify relations between multimedia objects of both determined and undetermined duration. Secondly, the temporal relations describe both the existing arrangement of the medium, and dependency relations between media. Finally, a powerful temporal Petri net is considered to model the temporal and interactive relations.
