Résumé
Reconciling Software Product Lines (SPL) and Service Oriented Architecture (SOA) allows modeling and implementing systems that systematically adapt their behavior in respond to surrounding context changes. Both approaches are complementary with regard to the variability and the dynamicity properties. Architecture Description Language (ADL), on the other hand, is recognized as an important element in the description and analysis of software properties. Different ADLs have been proposed in SOA or in SPL domains. Nevertheless, none of these ADLs allows describing variability and dynamicity features together in the context of service-oriented dynamic product lines. In this sense, our work attempts to describe the changing architecture of Dynamic Service-Oriented Product Lines (DSOPL). We propose an ADL that allows describing three types of information: architecture's structural elements, variability elements and system’s configuration. Furthermore, we introduce context elements on which service reconfiguration is based.
