This deliverable presents the approach to design service composition. It is composed of a process integrated within the SeCSE methodology, a composition language that extends the current the facto standard (BPEL), an approach to support testing of a composition. The architecture of the environment supporting the execution of a composition is also defined.

The deliverable will include a detailed process for the runtime composition, examples on how to apply the process in the scenarios, and refinement of the composition language.

This report describes our approaches to dynamic binding and (re)negotiation and how they relate to dynamic composition and discovery. An attempt to integrate these approaches in a unifying architecture is also made.
