RuCORD: Rule-based composite operation recovering and detection to support cooperative edition of (Meta)models

The cooperative edition of (meta)models may be enacted by the exchange of change operation journals between the participants. But these are often composed of atomic operations (create, delete, set, ...) that have no useful meaning for the users. Hence, detecting and recovering composite operations is a crucial step to help users understand the history of their (meta)models in terms of higher level operations. As a result, conflict detection, reconciliation, and merging of modeling artifacts will be improved. In addition, composite operations can also be used to generate model migration instructions that can automatically migrate instance models.
