ODP-based QoS-support in UML

Traditional systems development methodologies are not focused on the development of distributed systems. However, efforts to address these problems are going on within OMG, with the focus to standardise a meta-model for analysis and design methodologies. The initial submissions converged into a meta-model of Unified Modeling Language (UML), which is emerging as the standard from OMG. This meta-model defines a set of modelling elements that can be used by different methodologies supporting different domains. The authors investigate, in the context of open distributed processing (ODP), the support for the modelling of Quality of Service (QoS) in UML when modelling distributed multimedia applications. In the context of OMG´s architecture, they propose some extensions based on the current version of UML to support QoS and multimedia applications. They use a car computer system with Global Positioning System (GPS) support as an example
