Tahrir is a Flask application used by the Fedora Project for issuing Open Badges. As per the about page:

The concept of Open Badges originated among those working at the Mozilla and MacArthur foundations, and out of the research of Erin Knight, founding director of the Open Badges project at Mozilla.

Originally, information was hosted on the Mozilla Wiki.

Tahrir is Arabic for Liberation. The name is total overkill.

The project is hosted on Github. You can read the documentation for more details.

You can see Tahrir deployed in production, or in the staging instance.
