Research on Opportunities to integrate/develop Open Badges

At the Moment we are getting back to the idea of integrating Open Badges into our Projects. We are testing the Moodle 2.5 Badge Integration, the new Mahara Badge Displayer Blocktype Plugin and a couple of WordPress Plugins (e.g. WPBadger, BadgeOS….).

We are searching for (easy to understand) technical approachs to integrate and develop Mozilla Open Badges Issuer API at the moment, so this site is for collecting Links.
