Bidirectional transformations (Bx) are a mechanism for maintaining the consistency of two (or more) related sources of information, such as models in model-driven development, database schemas, or programs. Bx technologies have been developed for practical engineering purposes in many diverse fields. Different disciplines such as programming languages, graph transformations, software engineering, and databases have contributed to the concepts and theory of Bx.

However, so far, most efforts have been focused on the case where exactly two information sources must be kept consistent; the case of more than two has usually been considered as an afterthought. In many practical scenarios, it is essential to work with more than two information sources, but the community has hardly started to identify and address the research challenges that this brings.

Driven by the practical needs and usage scenarios from industry, this Dagstuhl Seminar will identify the challenges, issues and open research problems for multidirectional model transformations and synchronisations and sketch a road map for developing relevant concepts, theories and tools.

To increase the practical relevance of this seminar, participants from industry who could contribute with their practical experience, scenarios, challenges and problems are particularly encouraged to participate.
