Abstract

This paper describes the design and the implemen- tation of a framework for multimedia information management. The framework is built upon two notions. The one notion is a model that describes multimedia information management by (1) dening foundation objects that denes dierent aspects of multimedia management and by (2) providing a composition that brings those dierent aspects together in a consistent way and provides interoperability between them. The other notion is a distributed infrastructure, that is, CORBA, in which the model has been implemented. In this paper we give an overview of the COMMOTION model and its implementation. In the description of the implementation we focus on the implementation of a server and a client component. Our emphasis at the server side is the integration and implementation of standardized CORBA services as well as additional multimedia functionality. At the client side we empha- size the integration of existing frameworks/submodels into COMMOTION. Finally, we describe the main components we have built using the implementation.
