EMF Diff/Merge is a diff/merge tool for models. Its main purpose is to help build higher-level tools that need to merge models based on consistency rules. GUI components and higher-level tools, such as support for modeling patterns and model synchronization, are also provided. Typical usages include model refactoring, iterative model transformations, bridges between models or modeling tools, collaborative modeling environments, or versioning systems.
This is the Photon release of EMF Diff/Merge.
