“…There are few works that are oriented towards using the MDA approach to design adapted applications and obtain personnalized information. Vale and Hammoudi showed in (Vale, 2008) the importance of MDA in context modeling and context-aware applications development, and for that they designed the CSOA (Context-aware Service Oriented architecture) based on ECA viewpoints (Enterprise Collaboration Architecture). In the study (Ou, 2006), the authors have designed a contextual model using ontologies in order to represent context information, then they proposed a new architecture MDIA (Model Driven Integration Architecture) dedicated to the implementation of context-aware applications.…”

Nowadays, software engineering is moving towards the development of ubiquitous and distributed applications. This tendency is constrained by parameters such as mobility and heterogeneity that characterize the current situation of a user. Each new application will be able to adapt its services with the change of context of use and satisfy all user's preferences. The aim of this paper is to propose a new development approach that can take into account the change in context of use during the application development process. It permits us to develop contextual aspects of a system in a separate way and independently from the business aspects of this system and from the technological constraints of the chosen platform. Our proposal, based on the principles of MDA (Model Driven Architecture), is defined by three steps. First, the separation of contextual aspects by introducing the 3TUP process (3 Track Unified Process) and the development process as PSI "Ψ". Second, the context modeling using UML (Unified Modeling Language) and conform to a proposed context metamodel. And thirdly, the integration of the contextual model in MDA process using model merging operation.

“…The basic idea is to model the context parameters and their structures explicitly and to associate them with Web services descriptions. Examples of systems utilizing this way are CoWSAMI [16], ContextUML [39], CSOA [46], and their applications and works built atop them. Another technique of structure and data coupling is to develop/utilize agreed context models to pass context information.…”

Distributed services in a context-aware Web service system or in a service composition need to couple context information from different sources in order to be able to interpret context information. Such interpretation is a prerequisite before services can adapt themselves to be context-aware. However, context coupling in contextaware Web service systems is a complex issue. It is related not only to how we represent and transfer context information among Web services, but also to how we support the context storage, and how we ensure security and privacy issues of context information. Context coupling techniques for Web service systems will be different from that of tightly coupled systems because, with Web service systems, context information is typically shared across the boundaries of organizations which host Web services. This chapter aims at presenting an overview of context coupling techniques, their related issues, and their implication for a context-aware Web service system. Our approach is to study existing techniques implemented in current systems, to present open context coupling issues in current and future context-aware Web service systems, and to suggest further research directions.
