Résumé

With the recent advances in distributed systems and wireless technology, users can access any information, from anywhere with any device. Multimedia delivery services are currently under development to operate in such environments. In this context, it appears essential to offer and support different levels of service according to users requirements and expectations and to work towards quality-driven delivery (QDD). Implementing QDD mechanisms leads us to consider different issues such as system components interoperability, quality information management, distributed execution of QDD activities and multi-criteria optimization. In this paper, we focus on quality information management to support QDD. We propose a model management approach to the problem and we introduce metamodel and model operations for that purpose. We use conceptual graphs formalism to develop our QDD metamodel and we show how the conceptual graph derivation mechanism can be applied to implement some fundamental model operations.
