DAMASCo: A Framework for the Automatic Composition of Component-Based and Service-Oriented Architectures

Although the reuse of software entities has matured in recent years, it has not become standard practice yet, since reusing component-based or service-oriented architectures requires the selection, composition, adaptation and evolution of prefabricated software parts. Recent research approaches have tackled independently the discovery, composition, adaptation or monitoring processes. We present the DAMASCo architecture, a framework for composing pre-existing services and components. Using model transformation, context-awareness, semantic matchmaking, behavioural compatibility, dependency analysis, and fault tolerance, DAMASCo focuses on discovering, adapting and monitoring the composition of context-aware services and components in mobile and pervasive systems. DAMASCo is made up of a set of tools that implement the different processes, which have been evaluated on several examples.
