Challenges in Model Synchronization for Information Preservation Illustrated with the FACE and AADL Standards

This article explores the challenges in Model Synchronization in Model Driven Engineering, focusing on Information Preservation. It introduces modern architecture description languages such as FACE and AADL and describes the challenges in reliably maintaining consistency of their models, as well as determining how to propagate changes of one model to the other. It describes ongoing efforts including improving Information Preservation in model synchronization approaches such as Triple Graph Grammars, as well as the required foundations and ideas for the establishing effective Model Management and Synchronization frameworks.
