EMF Diff/Merge provides a lightweight engine for comparing and merging models using IDs.
- The scope is 2-way and 3-way comparison of arbitrary EMF models (or "instance models").
- Model elements are matched by ID, where an ID can be any "signature" that uniquely identifies the element within its scope: Ecore ID, XML ID, qualified name, location in model tree, etc.
- A GUI with reusable UI components is also included.
Besides, the tool is intended to satisfy the following requirements.
It must support the comparison and merge of large models. There is thus an emphasis on scalability and reliability.
The final goal is to obtain a mature, versatile building block for multiple usages: version control, incremental model transformations, model refactoring, etc.
The EMF Diff/Merge project is part of EMF.
