Using versioning systems to store Stambia models, such as Metadata, Mappings, or Processes might be difficult to handle the conflicts with the resources.

When there is a conflict handling the changes and understanding them is complex because the Stambia Models are XML files, and so performing merges can be painful.

EMF Compare tool has been added to allow to compare more easily such XML models and to make the usage of versioning easier with Stambia.

This article porpose is to show how to use this tool in stambia DI.

Prerequisites:
  • This article is dedicated to Stambia DI 2020 (S20.4.0) or higher.
