I have put OSM Analytic Difference Engine on github. In short its a backend for a live service providing real-time insight into edits within a region of interest. Special focus has been made to analyse the changesets and provide a concise description of what has changed.

Some of purposes of this engine:

• Prof-of-concept for an improved changeset-info service (improved compared to looking up changeset details on osm.org)
• Provide insight into changes in your area of interest
• Improve team spirit of a regional OSM team/task-force.
• Quality insurance through peer review
• Learning by seeing how other make edits to your region of interest.

The service is available as a web-service and provide three different information elements:

• An overall summary with a overview map containing bounding boxes of recent edits
• A list of changesets with analytic details
• A visual diff for the changes of each changeset (try the ‘VisualDiff’ link on each changeset)

Example of the analytic details:
