T2M and M2T Transformations between Software Processes and Software Process Models

Formalizing software processes allows process engineers to analyze, simulate, evolve and manipulate them with different purposes. Eclipse Process Framework Composer is a free tool for formalizing SPEM 2.0 processes, it provides primitives for process definition and allows to graphically visualize processes. This user friendliness is crucial for practitioners to both follow the designed process and to validate it. For the last two years we have been working in tailoring software process models, i.e. configuring general processes to particular contexts in order to make them more productive. However, it is hard for end users to validate the results and follow the process if it is in its model format, i.e., xmi. Moreover, manual translation is hard and error prone. In this paper we present a set of projectors: an injector that transforms the xml description of the process into xmi, and a extractor that transforms the xmi description of the configured process into the xml epresentation needed for its visualization.
