Modern software-intensive systems serve diverse stakeholder groups and thus must address a variety of stakeholder concerns. These concern spaces are often associated with specialized description languages and technologies that are based on concern-specific problem and solution concepts. Software developers are thus faced with the challenging task of integrating the different languages and associated technologies used to produce software artifacts in the different concern spaces.

GEMOC 2013 is a half-day workshop that will bring together researchers and practitioners in the modeling languages community to discuss the challenges associated with integrating multiple, heterogeneous modeling languages. The languages of interest range from requirements to runtime languages, and include both general-purpose and domain-specific languages. Challenges related to engineering composable languages, semantic composition of languages and to reasoning about systems described using heterogeneous languages are of particular interest.

GEMOC 2013 will provide an open forum for sharing experiences, problems and solutions on the conjoint use of multiple modeling languages. This workshop will be the place where concrete artifacts, ideas and opinion are exchanged and constructive feedback provided. A major objective is to encourage collaborations and to start building a community that is focused on solving the problems arising from such a globalization of modeling languages.
