One of the key activities needed to construct a quality service-oriented solution is the specification of the architectural elements. The selection of an appropriate and proven method for specification of the elements consisting services, flows and components is thus quite crucial to the success of any service-based solution. Existing methods for service(More)
BPEL provides a workflow-oriented composition model for service-oriented solutions that facilitates the system integration through orchestration and choreography of services. In some cases, BPEL process designs can be highly complex owing to the vast number of services executed in global markets. Such heavy coupling and context dependency with partners in(More)

Model-Driven Development (MDD) is based on the premise of giving software engineers the most suitable infrastructure, based on which they can easily construct and transform their artifacts. Several paradigms like linear four-layer infrastructure have been proposed to facilitate MDD requirements. Although recently proposed paradigms have their own advantages(More)
Service specification is the core of the service-oriented modeling activity and focuses on elaborating the detailed design of the services, flows and components. Therefore, the selection of an appropriate and proven method to conduct this activity is critical to the success of any service-based solution. Existing methods for service specification ignore the(More)
In order to better comply to new requirements or quick adjustment with changing requirements, service composition is used in the way of exploiting the capability of available services. Service composition is one of the most benefits of SOA. Since emerging of RESTful web services, the needs for heterogeneous composition have been raised and brought up new(More)
BPEL processes are workflow-oriented composite services for service-oriented solutions. Rapidly changing environment and turbulent market conditions require flexible BPEL processes to adapt with several modifications during their lifecycles. Such adaptability and flexibility requires the low degree of dependency or coupling between a BPEL process and its(More)
