New Publication @ETFA2016: On The Evolution of CAEX: A Language Engineering Perspective

Our paper On The Evolution of CAEX: A Language Engineering Perspective has been accepted for publication at ETFA 2016


CAEX is one of the most promising standards when it comes to data exchange between engineering tools in the production system automation domain. This is also reflected by the current emergence of AutomationML which uses CAEX as its core representation data format. Having such standards at hand, the question arises how to deal with the evolution of such standards as is currently happening with the transition from  CAEX 2.15 to CAEX 3.0.

In this paper, we take a language engineering point of view to the evolution of engineering data formats. In particular, we present how CAEX can be formulated in a model-based framework which allows to reason about evolution of the data format as well as its impact on the data stored in such evolving formats. By this, not only the migration process of existing data to the new format version is possible, but also a more theoretical investigation on data preservation is possible.We demonstrate the approach by the concrete case of the upcoming CAEX evolution.
