Open Badges
What it does
Django-badger is an issuing application. It is a web based software built on the python framework known as Django. You can either install Django-badger as a standalone service or you can install it as an 'extension' (know in the Django world as an 'app') for an existing Django Project.
In either case the application enables you to create badges, monitor learner progress towards a badge and award badges when learning criteria are reached.
As an example I installed Django-badger as an 'app' in my existing Booktype django project. Booktype is book produciton software (free software) written in Python using the Django framework. This means that the users of Booktype can be issued badges for activities linked to the sharing of content and collaborative book production.
While Django-badger is structured as a larger project and not strictly as a reusable app it doesn't take long to get it to work as an app.
