Audio Log
Good Morning everyone!
Simone Ravaoli: Good afternoon ;-)
Good afternoon! I am unable to connect through Linphone, any otheer option?
James Chartrand: I am using
Jim Goodell is scribing.
Thanks Jim- didn't want to volunteer because I wasn't sure what was needed!
Kim Hamilton Duffy: Alias: said something
Juan Caballero: Sorry can't scribe today, bad connection!
Nate agreed to scribe next week

Topic: Introductions and Reintroductions

Alex Jackl introduced himself
Juan Caballero: <-- AJackL mentioned being involved in this cool effort I'd never heard of until just now!
Juan Caballero: Also
Simone_Ravaioli has been working on standards across globe, with IMS & PESC, fan of Open Badges
Chris Huston with eLumen co-chair CLR with IMS introduced himself
Kim Hamilton Duffy: Chris Houston (CLR/IMS) introducing himself
Greg Nadeau talking about what goes inside the VC "envelope"

Topic: What's inside the credential envelope?

Slide 46 - put achievement (definition) on the outside of the envelope, the assertion on the inside
Juan Caballero: Thanks for that!
Greg Kidd: What badges does with DIDs is what CLR should do with DIDs (and others?)
Kim Hamilton Duffy: CEDS acronym is "common edu data standard"?
Alex Jackl: Beauty of having many work streams is that a lot of work being done, and there is coordination leading to a universal direction
Nate Otto: VC envelope and CLR/OB look a but different but there are ways of using it so that it can be compatible, e.g. achievement with a rubric with different achievement levels, can link achievement level from rubric
Juan Caballero: ^Hehe I was there! Didn
Juan Caballero: 'T understand much at the time, tho :D
Simone Ravaoli: +1 On Nate
Jim Goodell: CEDS is US edu-supported group focusing on data vocab, logical models [scribe assist by Kim Hamilton Duffy]
Kim Hamilton Duffy: ...Used for data at rest. doesn't get into data transport side of standards
Kim Hamilton Duffy: ...Has stayed connected with other data initiatives. U.S. and non-U.S.
Kim Hamilton Duffy: ...Can pull in improvements from different SDOs
Kim Hamilton Duffy: ...Can provide translations "rosetta stone"
Jim Goodell: For learner, wallet will need to support a range, but for "issuers" there will be specific focuses. Work through IEEE ILR happening will help [scribe assist by Kim Hamilton Duffy]
Chris Houston: SOn got a competency-based report card (shown in slide 2)
Chris Houston: SLide 3 shows JSON notation of the competency-based report card assertion, would work inside the assertion envelope we've been talking about
Chris Houston: Rubric-criterion labels and competencies are the assertion
Simone Ravaoli: Can I add you to the q to give us your high-level thoughts on where similar work is happening in europe? (We'd like to ask you to lead a dedicated call to discuss in-depth later) [scribe assist by Kim Hamilton Duffy]
Chris Houston: Uses OB mechanism for email / hashing
Simone Ravaoli: Sure
Chris Houston: Associations used t place the assertion or the related achievement on a graph
Greg Kidd: There are some things I disagree with (how to approach similar solutions) It will not take months....we are working out differences
Nate Otto: Evolution of the CLR - candidate public final (available for public viewing) - no one has signed up to be a consumer implementation of CLR yet, 2 publisher implementations
Nate Otto: IMS leadership expressed some interest for compatibility to W3C VC, but not yet clear what that means...
Nate Otto: We should look at actual examples and code to see that it can work
Simone Ravaoli: CEN standard in EU then EC put financing into some ERASMOS projects...
Simone Ravaoli: Now EUROpass project EUROpass digital credential ecosystem EDCI
Kim Hamilton Duffy: I think/hope some of the T3 innovation network pilots will exercise the receiving side
Simone Ravaoli: Slight corrections on the scribe: CEN (not CEN), Erasmus+ (not Erasmos)... thanks so much Jim :-)
Kim Hamilton Duffy: (In addition to other POCs discussed)
Alex Jackl: This problem of not having people receiving the data is a problem across the ecosystem, receiving is the hardest part, effort not to creat a wallet that can hold the different forms of data... then people ready to accept that data ....
Simone Ravaoli: Thanks all
