Introduction

EMF Diff/Merge provides a lightweight engine for comparing and merging models using IDs.

Its scope covers:

  • 2-way and 3-way comparison of arbitrary EMF models (or "instance models").
  • Matching of model elements 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 simple GUI with reusable UI components.

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 order in which differences are merged must have no impact.

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.
