Service composition is the mechanism for building software applications by service integration. Service-based applications often require properties like dynamic or non-deterministic service selection that require a new definition of software application, which turns out to be very difficult to perform manually. There is a need to automate this process by providing tools and environments. These tools should allow to build flexible software applications and to ensure the consistency and completeness properties of the composition.
We focus on building software applications by composition, from design to execution. We propose both a service composition approach and a prototype named SELECTA that meets the needs and challenges of service composition such as: increasing the abstraction level for application specification (application models), incremental building of composites, consistency management and completeness of composites, definition of service constraints languages or service selection algorithms, automating the service selection process, providing a set of software environments and tools for designing, building and executing applications.
