Abstract :
This work enhances the current UML4ODP FDIS (Use of UML for ODP systems specification, final draft international standard) computational metamodel with QoS (quality of service) features relevant to distributed systems. We first introduce two new important concepts, namely; QoS-labeled interactions and QoS-embedded interfaces. Based on these, we provide a UML metamodel of interfaces and interaction signatures. The final metamodel being a first step towards a QoS-embedded computational metamodel. Finally, we redefine computational rules in a compact manner thanks to the new concepts introduced, as well as we make use of the OCL (object constraints language) language.
