A Domain Specific Transformation Language to Support the Interactive Definition of Model Transformation Rules

Abstract. Model-driven engineering (MDE) is a new software develop-ment paradigm that intends to improve software construction by raising the abstraction level through the use of models and transformations. Re-cently, MDE has also been used for automatic change evolution and in particular for tailoring software processes. Even though there are some proposals for automatically generating part of the transformation mod-els, they are not easily applicable in the software industry because the potential users usually do not have the capabilities of developing or main-taining transformations. Proposals trying to address this problem should balance the formality required by MDE and the usability needed by the users. This research applies higher-order transformations (HOTs) and decision models for generating transformations to tailor software process models with no direct user interaction with the code. To that end, a graphical interface was defined with such a purpose, so that transfor-mation rules are interactively defined using a domain specific languaje (DSL), and the tailoring transformation is automatically generated and applied using a domain specific transformation language (DSTL)
