OB Background■ Learners are learning everywhere
– But most of that learning doesn’t “count”.
■ Skills assessment and communication is limited in current system.
■ Few alternatives to the current accreditation/credentialing system.
OB Goals■ Develop badges as an alternative
(micro-)accreditation/(micro-)credentialing system.
■ Avoid silos. Support badges from multiple issuers across the web.
■ Optimize value: make badges remixable and shareable with different audiences/sites.
■ Develop an open and decentralized supporting infrastructure to give learners control of the entire ecosystem.

Issuers■ Organization, consortium or individual
who issues badges into the OBI.■ Issuer issues a badge on their site, then
prompts the Badge Earner to push the badge into their Backpack.
■ Issuer badge systems are independent of the Infrastructure.

Badges are not assessments.
Badge Earner■ A person storing their badges within
the OBI.■ The Earner has interactions with
Issuers to earn badges, then can manage and share the badges in their Backpack out to various Display sites.
■ Learners are a type of Badge Earners.
Badge Backpack■ An authorized data storage plus a
management interface (control, share) for Earners.
■ Open source and federated – anyone can take the code and fork it.
■ Mozilla is building a reference or default Backpack.
Badge
■ A single credential demonstrating a skill, achievement, quality or affiliation.
■ More than a static image or button: its value comes from the information or metadata attached to it.
Badge – inside■ A JSON blob of metadata embedded in
a PNG file (“Badge Baking”).‣ Easily portable, an actual “thing” that
can be emailed around carrying all the information with it.
‣ Important for decentralization, so that Earners have more control.
Badge – metadata■ Who issued the badge.■ The issue date.■ How the badge was earned.■ Hyperlinks back to artifacts,
documents, or testimonials demonstrating the work that lead to earning the badge.
■ Authentication back to the issuer.
Verification■ “Did the Issuer issue this badge?”,
“Is it still valid or has it expired?”, etc.■ Verification happens between the
Displayer and the Issuer.■ Hosted Assertions: metadata points to
a URL that the Displayers can ping.■ In the future OBI will support Signed
Assertions.
Displayers■ Display of badges is where a significant
part of the value lies: badges are not siloed or stuck within one site.
■ Earner controls through the Backpack where badges are displayed.
■ Earners can also make badges public and discoverable through the Earner’s email address.
Identity■ Identity is a critical part of the OBI.■ Identity needs to be open and
decentralized.■ How? Persona, fka BrowserID.
browserid.org wiki.mozilla.org/Identity‣ People understand email address■ They don’t understand OpenID
■ Anyone can issue accreditations about anything.
■ People can keep their own backpacks full of credentials.‣ Access & display control. ‣ Attached to detailed accreditation
info and evidence.‣ Linked back to issuers.
Conclusions (1)
“— The Chronicle of Higher Education
Compared with the new open badge systems, the standard college transcript looks like a sad and archaic thing.
■ OBI as an open infrastructure for presentation portfolios.
■ OBI separates the credentialing and teaching functions of higher education.
■ What about assessment?
Conclusions (2)
“— David Wiley
…no one is paying sufficient attention to the gap between learning anything anywhere (OER) and receiving a recognition (OBI) – this gap is called “assessment.”
“— David Wiley
…many in the field are overlooking the place where badges make the most sense of all – the formal higher education institution.
Moodle & Mahara
■ Totara Learning Solutions will be developing an Open Badges solution for Moodle and Mahara.‣ Moodle as Issuer.‣ Mahara as Displayer.
