Title: Approaches to model transformation reuse – From concepts to a-posteriori typing

Abstract. Models are the main assets of Model-Driven Engineering (MDE), and hence model transformations are essential to automate the model manipulations required by MDE. Different kinds of transformations are common in MDE, like in-place, model-to-model, or model-to-text. In all cases, their definition is based on the meta-models of the models to be manipulated. However, the proliferation of meta-models in MDE (e.g., in connection with Domain-Specific Languages, DSLs) complicates transformation reuse. This is so as transformations are defined for particular meta-models and are not applicable to other meta-models, even if they have some commonalities. Therefore, in order to facilitate the creation of DSL-based MDE solutions, flexible means to reuse transformations across heterogeneous meta-models are required.
In this presentation, we will explore several approaches to transformation reuse. First, taking inspiration from generic programming, we propose concepts, gathering the requirements needed from meta-models to qualify for a model transformation [1]. This way, transformations are defined over concepts and become reusable by binding the concept to concrete meta-models. The binding induces an adaptation of the transformation, which becomes applicable to the bound meta-model.
Concepts can also be interpreted as meta-meta-models defining a set of candidate meta-models for the transformation. Hence, we will explore multi-level modelling to express reusable transformations [3]. However, this approach requires using the domain meta-meta-model to construct the meta-models and prevents unanticipated reuse. Hence, the talk will end presenting a-posteriori typing. This is as a means to provide models with additional types beyond their creation meta-model [2], so that transformations defined for such types become reusable for those models. Moreover, decoupling object creation from typing permits embedding simple transformations in the conformance relation.
