Presentation

The EMF Compare project is part of EMFT (EMF Technology).

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.


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.

Compatibility

The EMF Compare development team does its best to maintain downward compatibility towards Europa (3.3). Following is the compatibility chart :

EMF Compare Eclipse 3.2 - EMF 2.2 Eclipse 3.3 - EMF 2.3 Eclipse 3.4 - EMF 2.4 Eclipse 3.5 - EMF 2.5
0.7 OK
0.8 KO OK OK
1.0 KO OK OK OK

An empty cell indicates that the compatibility hasn't been tested for a particular combination.
