i want to introduce Gerrie  to you.
Gerrie is a crawler for Googles code review system Gerrit.
As far as i know, the Wikimedia community, use Gerrit to improve and
develop various products like Mediawiki, Wiki-Extensions, Infrastructure
and so on. The Gerrit instance is located at gerrit.wikimedia.org
During this activity a lot of interesting data will be created in the
background. Gerrie is a tool to transform this data into a RDBMS like
MySQL. After this you can create analysis with it with simple sql queries.
To retrieve the data the SSH API of Gerrit will be used. The benefit from
this is you can use every Gerrit system to analyze like TYPO3 . I assume
that most of you are registered at gerrit.wikimedia.org
 and entered
their SSH public key into the system. Gratulations, you are ready to crawl
the data as well.
Gerrie is written in PHP and complete documented .
Even the database scheme is documented  to help you to analyze the data.
For a quickstart you can follow the documented Getting started guide .
Results of this analysis are wide spreaded.
One use case can be for example a gamification analysis like the Activity
Monitor build upon TYPO3s Gerrit data for the TYPO3.CMS (main content
management system) product:
In this analysis every activity will results into points. Based on the sum
of the points a score list will be created. The background color is
determined by a hash function based on the users name. This mean: Same Name
= Same color.
Please take in mind: This does not reflect the contribution to the
community. This displays only activity by a user in a specific system.
I would love to see you as a kind of tester for this tool.
If you need help, do not hesitate to ask. I try to help as much as possible.
Have fun during testing.
