EMF Compare brings model comparison to the EMF framework, this tool provides generic support for any kind of metamodel in order to compare and merge models. The objectives of this component are to provide a stable and efficient generic implementation of model comparison and to provide an extensible framework for specific needs.

EMF Compare provides :

• A Standalone Core allowing you to compare any kind of EMF model using EMF Compare as a Java Jar, not even needing an Eclipse runtime.
• Team providers integration within Eclipse : support for SVN, CVS and GIT.
• An Extensible Framework allowing you to plugin any matching or diff behavior specialized for your own model.

The comparison process is divided in 2 phases: matching and differencing. The matching phase browses the model version figuring out which element comes from which other one, then the differencing process browses the matching result and create the corresponding delta. This delta may itself be serialized as a model.

Global architecture

EMF Compare has been released in 1.0 version and is now part of EMF. Next release is planned for June 2011, synchronized with the Indigo release. You may stay tuned to what's going by watching this blog's RSS feed.
