A Model Repository for Collaborative Modeling with the Jazz Development Platform

Today's software development projects have a huge demand for a comprehensive and integrated support in the team-based development of models. Since they typically rely on file-based version control systems such as CVS and assume that working with models does not differ from working with code, current solutions solve only one part of the problem. This paper addresses this gap between what is needed in practice and what is provided by existing tools. Based on the collaboration platform Jazz, a model repository prototype is developed that provides adequate versioning support and leverages the collaboration mechanisms provided by Jazz for concurrent model development. Especially the integration of concurrently developed models turned out to be a complex and collaborative task. The results of this investigation are integrated into the prototype yielding a model repository that supports team-based development to a considerable extent.
