An UML-Based Meta-Language for the QOS-Aware Enterprise Specification of Open Distributed Systems

We address in this paper the need to develop appropriate notations for the QoS-aware specification of the ODP (Open Distributed Processing) enterprise viewpoint. The Unified Modelling Language (UML) is currently emerging as de facto standard for formal object-oriented modelling. Several approaches are being used in the field of the formalization of UML. For several reasons, we use the metamodelling approach in our work. We analyze the QoS concepts defined in QoS foundation modelling concepts part and in the QoS in enterprise specification part. The result is an UML meta-model of the core QoS concepts and their relationships, which is considered as the abstract syntax of a concrete language for QoS-aware ODP enterprise specifications.
