Retainment Rules for Model Transformations

Abstract

The goal of the workshop was to exchange ideas and experiences relatedto Model (Co-)evolution and Consistency Management (MCCM) in thecontext of Model-Driven Engineering (MDE). Contemporary MDE practicestypically include the manipulation and transformation of a largeand heterogeneous set of models. This heterogeneity exhibits itselfin different guises ranging from notational differences to semanticcontent-wise variations. These differences need to be carefully managedin order to arrive at a consistent specification that is adaptableto change. This requires a dedicated activity in the developmentprocess and a rigourous adoption of techniques such as model differencing,model comparison, model refactoring, model (in)consistency management,model versioning, and model merging. The workshop invited submissionsfrom both academia and industry on these topics, as well as experiencereports on the effective management of models, metamodels, and modeltransformations. We selected ten high-quality contributions out ofwhich we included two as best-papers in the workshop reader. As aresult of the high number of participants and the nice mix of backgroundswe were able to debate lively over a number of pertinent questionsthat challenge our field.
