* Representation - Chunks of JSON data embedded into a PNG file
* [ Badge Assertion aka Badge Manifest ] - Earner identity information (<algorithm>$<hash(email + salt)>) plus badge information (JSON metadata)
* Verified Badge - Badges that have an assertion URL. OBI currently supports verification of badges through Hosted Assertions. i.e. When Issuer pushes badge to the OBI, metadata is pushed to a unique and persistent url aka assertion url. Issuer maintains Badge Assertion and Displayers can ping the assertion URL to confirm verification.
** n.b. Signed Assertion is on the development roadmap.
