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. The main contributions are:
- A more flexible UI (optional section, inter-view sync)
- An improved extendibility (complete comparison behavior)
- Some bug fixes (UI, Git integration)
- A slight performance improvement (directed comparisons)
The project leadership certifies that the APIs in this release are "Eclipse Quality".
EMF Diff/Merge has been designed with extensibility and integrability in mind. Consequently, it has been integrated into various modeling environments for very different usages: classical versioning, model reuse, model synchronization.
No security issue identified.
The complete EMF Diff/Merge documentation is available from the EMF Diff/Merge Wiki page:
- General information (Introduction, Context and issues, Tool overview, Principle of the solution)
- Usage: Programmatic and via default GUI
- Complete javadoc
- Applications and Presentations
- Download information

Among the applications mentioned, one refers to the wiki page dedicated to Modeling Patterns, another one to the wiki page dedicated to Co-Evolution, and a last one to the wiki page dedicated to Model Patches. These pages are structured similarly to the main page.
EMF Diff/Merge intends to conform to the User Interface Guidelines.
No EMF Diff/Merge component is deprecated so far.
EMF Diff/Merge does not implement any standard.
EMF Diff/Merge obtained the "Most innovative project/feature" award at EclipseCon NA 2013. The forum, bugzilla and Gerrit show activity by different people and organizations. Gerrit pull requests have been submitted by people external to the project. EMF Diff/Merge is known to be distributed within modeling tools such as Polarsys Capella or Intel Cofluent Studio. Presentations have been regularly made at EclipseCon.
