==== Match/Diff/Merge on elements not contained in a EMF Resource ====

[[Category:EMF_Compare]]
The framework can be used on any kind of EObjects, but as historically it was about providing model comparison support for file based models many parts of the code are making assumptions about a resource being there or not.
+
 
+
We should build a strong test basis with eObjects not being in resources, being compared and merged.
+
 
+
==== MatchModel maintenance on incremental changes ====
+
 
+
Right now the match process is not split in several parts, and as such when one of the matched models has been changed all the resource set needs to be matched again.
+
We should be able to maintain parts of the match model and update those when the matched models have been changed.
+

==== DiffModel maintenance on incremental changes ====

Once the match model is maintained incrementaly, the next step is to maintain the diff model accordingly.

+
Several adopters expressed their will to reuse parts of the compare UI. Right now it's nor really doable as the UI is pretty tied to the Eclipse compare framework.

This task is about defining a new API one can easily reuse splitting content provider and viewers just like JFace.

Plan

Long Term

EMF Compare's focus is on providing a powerful, stable and proven framework for model comparison and merging. The API should be usable in any context from the plain Java application to the complete IDE customization.

Release Schedule

The calendar is available in the following formats: ICal, ATOM News Feed, HTML
