The Fourth International Comparing Modeling Approaches (CMA) workshop continues the work begun at CMA workshops held at previous MODELS conferences, Requirements Engineering (RE) 2013, and previous Bellairs Workshops. The Bellairs workshops produced a focused case study suitable for modeling in its entirety based on a Crisis Management System case study, and a preliminary collection of criteria to compare aspect-oriented modeling (AOM) approaches along with more traditional object-oriented modeling (OOM) approaches.

Each CMA workshop has produced a revised set of criteria along with evaluations of additional modeling approaches that have broadened the modeling paradigms beyond the initial scope of AOM and OOM. The 2013 edition of the CMA workshop at MODELS (CMA@MODELS'13) will bring together practitioners of different modeling approaches with the following two aims in mind: to continue applying the comparison criteria to more modeling approaches in the context of the focused case study, and to propose and execute analyses of the existing results, with the end goal of enabling practitioners to propose and evaluate end-to-end methodologies.

The workshop is co-located with the ACM/IEEE 16th International Conference on Model Driven Engineering Languages and Systems (MODELS 2013) in Miami, Florida, USA, in September/October 2013. Accepted papers will become part of the workshop proceedings and published in CEUR, which is indexed by DBLP. Accepted models including assessments will be published in the Repository for Model Driven Development (ReMoDD). After the workshop, participants are strongly encouraged to participate in publication of the workshop report which will be part of the workshop proceeding, and a more comprehensive journal publication effort spanning results from previous workshops that will focus on the insights gained during the workshops.
