A Temporal Data Model for Multimedia Database Systems

The presented data model is a novel approach for integrating temporal concepts into a multimedia database system. Multimedia objects are extended with the traditional time dimensions valid time and transaction time. In addition a new time dimension specifically tailored for multimedia data types is presented with semantics that are completely orthogonal to the already established time dimensions, valid time and transaction time, i.e., the model supports a 3D time for multimedia data. This new time dimension, the play time dimension, places the building blocks of multimedia data in a temporal structure for multimedia presentation. This model is currently being implemented in a MMDBS for distance education at UNIK, University of Oslo.
