Mozilla Open Badge Infrastructure
Example
P2PU:
"In order to allow you to share your badges with other sites and communities, P2PU has plugged into the Mozilla Open Badge Infrastructure (OBI), which allows you to manage a single badge collection, including badges from P2PU as well as other badge issuers and learning providers across the web, and then manage those badges and share them out accordingly. The OBI is using BrowserID, which will allow you to maintain a single identity through the email address you registered at P2PU.
The OBI is currently in the alpha version with means limited functionality and only 1 issuer - P2PU. Mozilla is launching the beta version with more functionality and a handful of additional issuers in the following months and this will be followed by the public 1.0 launch in 2012. At that point all issuers will be able to join and there will be even more of a badge ecosystem. If you send your P2PU badges now, they will be rolled over with each release and you will seamlessly capitalize on the new features as they are completed."
