Leveraging the Model-Driven Architecture for Service Choreography in Ubiquitous Systems
In ubiquitous systems, the context information (location, time, networking conditions, etc.) may influence the way of operation or even require to guarantee the availability of particular services at a certain moment. As a consequence, service composition may become more complex from a design viewpoint, due to the need of systematically taking into account all the variations of the contextual information in order to adapt the behavior of the set of involved services. Business Process Model and Notation 2.0 (BPMN 2.0) can be used to specify process choreography, which helps modeling service composition. Even so, the peculiarities of ubiquitous systems make it difficult to actually obtain an executable model that fulfills the mobility, availability and adaptability requirements of these systems. In this paper, it is presented a Model-Driven Architecture (MDA) approach to transform a BPMN choreography model into software templates for specific target platforms. The proposal has been implemented making use of the Eclipse Modeling Framework (EMF).
