Somewhat cleaned up version of the MediaWiki Dump Analysis code from the wredese project. I must warn you, that I haven't really spend much time cleaning up that code. And when I was writing the original version, I was concentrating on a get-results-quick-and-dirty approach, rather than on designing beautiful and reusable code.

Requirements:

• Python 2.6+, Linux;
• OrderedDict (available in Python 2.7 or http://pypi.python.org/pypi/ordereddict/)
• 7-Zip (command line 7za, sudo apt-get install p7zip-full)

Input Alternatives:

• Wikipedia history dump (e.g. enwiki-20100130-pages-meta-history.xml.7z);
• Wikipedia page(s) name / category;
• Wikipedia page(s) history (.xml/.7z/.bz2/.gz).

Input Processing:

• Detects reverts, reverted edits, revert wars, self-reverts;
• Filtering, labeled revisions data sets management, etc;
• Calculates users/page counters, revert rates, page diffs, etc (~1 week/C2Duo/Full English Wikipedia dump).

See more details in the project's http://code.google.com/p/pymwdat/source/browse/trunk/README file.
