What is Mozilla’s Open Badge Infrastructure?
Mozilla’s Open Badge infrastructure provides the open, core technology to support an ecosystem of badges. It is designed to support a broad range of different badge issuers, and allow any user to earn badges across different issuers, web sites and experiences, then combine them into a single collection tied to their identity. This collection of badges can then be shared out to various audiences across the web, resulting in real-world results like jobs or formal credit. http://openbadges.org/about/
