OpenAttribute was a project that came out of the Mozilla Drumbeat festival in 2010. The idea was to make correctly attributing licensed content as easy as possible. This is a key challenge in open education.
OpenAttribute started as a firefox plugin (which I modified slightly) and grew to include a chrome extension and opera extension, as well as a WordPress and Drupal plugin. I wrote the WordPress plugin, and help maintain the drupal plugin.
From these extensions, I added two new browser plugins. The first, automatically adds licensing to pictures and the second shows you which links on a webpage are links to creative commons licensed content.
