Audio Log
Nate Otto: ...Will be present once the bluetooth can be wrestled into letting me have audio...
Simone Ravaoli: Hello everyone ! Looking forward to today's call ... a nice #EasterEgg in the OpenBadges spec ?
Yancy Ribbens: What yancy said [scribe assist by Kim Hamilton Duffy]
Simone Ravaoli is scribing.
Kim Hamilton Duffy: Introduce the agenda and speakers

Topic: Introductions & Reintroductions

Kim Hamilton Duffy: Calling for introductions.
Kim Hamilton Duffy: Tayken
Taylor Kendall: Taylor Kendal Chief Program Officer at Learning Economy... involved in the ecosystem with similar work

Topic: DID support in Open Badges

Kim Hamilton Duffy: Speaker Gabe Cohen from Workday and Nate Otto form Concentric Sky on a recent issue added to the Open Badges githup to add DID method to OB
Kim Hamilton Duffy: Great intro, thanks Nate!
Gabe Cohen: The proposal liked in PDF from the Github Issue above is to add a DID-based identifier type to the list of profile identifier properties. [scribe assist by Nate Otto]
Gabe Cohen: A couple issues have been brought up as to how you include the DID; how you prove ownership of the DID. Nate has brought up some good points around how how this needs to be easy. [scribe assist by Nate Otto]
Kim Hamilton Duffy: It looks like Simone got booted off the call
Kim Hamilton Duffy: Oh, I see Nate's taking over. Would someone else mind scribing since Nate is co-presenting? it's very distracting
Gabe Cohen: One great tool available for us is the DIF Universal Resolver. That can get us access to the DID documents. We should next work on challenges for proof of control of a DID. [scribe assist by Nate Otto]
Kim Hamilton Duffy: ...To try to present and scribe :)
Gabe Cohen: This change would allow badges to be more closely tied into the decentralized world. There may be benefits to having badges issued to DIDs instead of issuers or telephone numbers. This moves the control slightly toward the learner, and opens up more opportunities in the future for that. [scribe assist by Nate Otto]
Gabe Cohen: We may find that DIDs have more longevity than emails or telephone numbers, as they are self-sovereign. [scribe assist by Nate Otto]
Kim Hamilton Duffy: Did:work:2UUHQCd4psvkPLZGnWY33L
I am back can continue to scribe...
Kim Hamilton Duffy: ... If we made the OB Data Model udnerstand DID, that would be a new instruction for implementers to use DID resolvers...
Kim Hamilton Duffy: ... Interested to hear from Nate
Nate Otto: Real issue is usability - how canwe make this identities visible to users, resvolvable by. users and implementers
Nate Otto: The issue and recipient and consumer inspector should be on the same page to understand the pointer to the individual and for the individual to approve that
Nate Otto: Increase capabilites of verifying that the individual control that string .. whether it is a DID or a URL...
Kim Hamilton Duffy: Did:work method:
Kim Hamilton Duffy: Workday team presents a description of the Workday DID Resolver Method and a demo of the user-with-a-DID authentication process as it might be implemented by another partner in the task force
Matt Lisle is scribing.
Nate Otto: Did work interesting did method to test out interoprability... idea: use workday's did process, something to prototype in this group... comments?
Nate Otto: To adopt changes to spec, need early implementers to try things out... this group might be avenue. lots of other implementers availalbe to try openbadges + SSI
In order to pursue proof of concepts, need some agreement on did methods that implementers want to try out
Kim Hamilton Duffy: Some assignee creates and presents an example credential that uses a DID for recipient identification that exemplifies the "Verifiable Credentials for Education" use case: recognition that a recipient has attained a particular "defined achievement", such as a Certificate (awarded on program completion)
Kim Hamilton Duffy: Interest in DID-web as well as workday's method... test out recipients using different did methods... testing authentication
Kim Hamilton Duffy: Some assignee creates an alternate example set showing how two different issuers might recognize that a recipient has attained a level o mastery of a competency that is defined by a third party (this is not something that is well handled by the Open Badges spec as it currently stands).
Kim Hamilton Duffy: Assumption that there is a learner wallet in order to try these out
Nate Otto: Badgr is service agent-type pattern... each user has an account, service acts on their behalf... another paradigm is wallet. case of DID authentication is perfect use case for 2 paradigms to work togehter (e.g. badgr account and wallet)
Kim Hamilton Duffy: Idea of wallet... most think mobile app, but can also be web app/site. could demo both
Interest in doing both VC and Openbadges prototypes... (DID support in OB perhaps more feasible than VC in OB)
DIDs into OB2.2 is a clear, measurable and achievable objective
(FYI... gotta drop off in a few minutes for next meeting... new scribe needed if we run over)
Nate Otto is scribing.
Kim Hamilton Duffy: We'll revisit this topic in future meetings. We want to figure out a good plan so we can move forward.
Kim Hamilton Duffy: We'll start talking about plans for that in future meetings. Thank you
