A Modeling Approach for Adaptable Service Oriented Systems based on Domain Specific Language Engineering

Nowadays, Model Driven Software engineering (MDSD) is a very dynamic field of research. This approach has introduced a major evolution to software engineering. Nevertheless the full code generation always stays a not reached objective. On the other side the simultaneous use of Context Aware Computing (CAC) and Service Oriented Computing (SOC) paradigms must raise many challenges. Particularly, the challenge of engineering such systems, which consists of the definition of modeling approaches, processes, techniques and tools to facilitate construction of these systems. The use of Domain Specific Modeling (DSM) approach for Context Aware and Service Oriented Systems brings an answer to these concerns. In this paper, we propose a DSM approach for adaptable service oriented systems named CADSSO (Context Aware, Domain Specific and Service Oriented) modeling approach. Our modeling approach is based on five models: domain specific services model (conforms to a domain specific services metamodel) which represents the domain specific services; service variability model (conforms to our service variability metamodel), it formulates services forms of adaptation; domain specific context model (conforms to our context meta-model), symbolize the services context of use; adaptation rules model, which is the joint between service variability model and context model; and domain specific business rules model, used to model domain specific business.
