UML Extensions for Service-Oriented Systems

A trend in software engineering is towards model-driven development. Models are used to document requirements, design results, and analysis in early phases of the development process. However, the aim of modeling is very often more ambitious as models are used for automatic generation in so-called model-driven engineering approaches. The relevance of models leads to the need of both, high-level domain specific modeling languages (DSML), and metamodels which are the basis for the definition of model transformations and code generation. For the service-oriented computing domain we developed within the SENSORIA project a DSML for building and transforming SOA models. This DSML is defined as a family of UML profiles, which complement the SoaML profile for the specification of SOAs structure. Our family of profiles focus on orchestration of services, service-level agreements, nonfunctional properties of services, implementation of service modes and service deployment.
