Abstract: Multimedia task management(MTM) is the automation of a business process for supporting multimedia content in whole or part. To achieve the function of MTM, the multimedia business process must be abstracted from the real world and described by a kind of formal method. The result is process model. This paper presented a novel approach,called GOMM,for modeling and implementing the process model using a graph-oriented multimedia model(GOMM).The GOMM constitutes a self-contained piece of multimedia content that indivisibly unites three of the content's aspeels, namely the media aspect, the semantic aspect, and the functional aspect, as well as the versioning information. The model provides means for the integration of ontological knowledge within a GOMM's graph structure. A formal definilion was proposed for GOMM graphs.

Key words: Multimedia task management, Graph-oriented modeling, Process model
