Domain-specific language for coordination patterns

The composition of software systems in a new one requires a good architectural design phase to speed up remote communications between these systems. But at the implementation phase, the code to coordinate such components ends up mixed in the main business code. This leads to maintenance problems, raising the need of, on the one hand, separate the coordination code from the business code, and on the other hand provide mechanisms for analysis and comprehension of the architectural decisions once made. In this context our aim is at developing a domain-specific language, CoordL, to write coordination patterns. From our point of view, coordination patterns are abstractions, in a graph form, over the composition of coordination statements from the system code. These patterns would allow us to identify, by means of patternbased graph search strategies, the code responsible for the coordination of the several components in a system. The recovering and separation of the architectural decisions for a better comprehension of the software is the main purpose of this pattern language.
