= Description =
== Abstract ==
Find python libraries that can compute / visualize differences between revisions of same mimetype. 

== Details ==
We already have:
 * text diff (python difflib)
 * image diff (PIL, python imaging)

We don't have:
 * xml text diff
 * html diff
 * other diffs - what makes sense?
 * how can we compare and visualize differences for other mimetypes (e.g. image, video or audio)?
  * what python libraries can we use? under what license are these libs available?
  * how does the diff look like?
  * is the lib pure python or does it need compilation / binary packages?

Your task is to find a ''good'' and ''makes-sense'' solution for 1 not-yet-supported mimetype.

== Benefits ==
After a successful research we will be able to implement a diff tool. This could be a followup task.
