Topic: W3C TPAC and Credentials CG

Manu Sporny:  First up, cover TPAC.
Manu Sporny:  Announcement coming tomorrow about payments wg 
  discussion at TPAC
Manu Sporny:  We're looking for volunteers to spend 5-10 minutes 
  about credentials outside of payments, including the biz case 
  your org has. Any volunteers?

Manu Sporny:  Great…will talk about details offline
Manu Sporny:  Expectation is to create a rough framework for the 
  hour
Mary Bold:  Suggest we also reserve 5 minutes for accreditrust / 
  mary / erik korb
Mary Bold:  To round out issues based on what people are saying
Manu Sporny:  Sunny / chris, is there a prepared statement about 
  badge alliance?
Sunny Lee:  We'll talk about it and get back to you
Manu Sporny:  Av facilities are great
Sunny Lee:  Cool
Manu Sporny:  1 Hour slot on credentials on monday
Manu Sporny:  Tuesday dedicated slot for credentials cg to meet 
  face to face 11am - 3pm
Manu Sporny:  Room tbd
Manu Sporny:  Wednesday, 10k foot overview of credentials for W3C 
  orgs
Manu Sporny:  Weds overview will include payments as well as 
  credentials
Manu Sporny:  Room and time on weds tbd
Manu Sporny:  TPAC has lots of credentials / payments time 
  allocated.
Manu Sporny:  Questions about TPAC?
Manu Sporny:  Next step is putting a slide deck together to 
  present at TPAC.

Topic: Credentials CG Use Cases Review

Manu Sporny: http://opencreds.org/specs/source/use-cases/
Manu Sporny:  We've taken the use cases / what if's and put it in 
  the document above
Manu Sporny:  It's a draft, expect use cases to be added or 
  dropped. use cases will be edited
Manu Sporny: 
  http://opencreds.org/specs/source/use-cases/#data-portability
Manu Sporny:  Doc starts with terminology…then overall design 
  criteria, specifically not use cases, but functionality we want 
  to support over time. things that won't go in the first version, 
  but we'll include down the line, so we don't want to prevent 
  them. first example is data portability.
Manu Sporny:  Questions on design criteria?
Bill Gebert:  I believe the design is general in nature and will 
  be specific over time.
Manu Sporny:  Any objections to the general approach?
Mark Leuba:  I agree with bill
Manu Sporny:  Having beent hrough this with web payments wg, this 
  approach results in fairly useful use cases. we can look back at 
  the use cases and figure out if we're overstepping our bounds. 
  reason for this approach is that some use cases dont' fit neatly 
  into a use case category
Manu Sporny:  Anything else about design criteria?
Manu Sporny: 
  http://opencreds.org/specs/source/use-cases/#data-portability
Manu Sporny:  Let's look at the data portability…ensuring 
  credentials can move between different data services
Manu Sporny:  Does anyone feel that the data portability example 
  isn't the right approach to design criteria?
Manu Sporny:  Someone who isn't familiar with our work should be 
  able to read the criteria and understand them
Manu Sporny:  Other criteria, data-rights - annotate credentials 
  to only be used for certain things. legacy-support - make sure we 
  can integrate with older credentialing systems, ie emails / 
  username password combinations. can't assume that the entire web 
  is going to support the credential specs. how does this integrate 
  with legacy systems? flexible-access-controls - access can be 
  provided interactive or non-interactive. example, "i authorize 
  this hospital to retrieve my credentials at any time" 
  reuse-extend-existing-tech - reuse things where we can, only 
  reinvent things when we can't avoid it
Manu Sporny:  Identifier-alignment came from nate otto, make sure 
  that 2 systems that have nothing to do with each other can align 
  systems on shared data…name & dob, social, etc. if they don't 
  want to use urls as an identifier. legacy system that doesn't 
  want to pull that complexity into their system. how to align db 
  records and user accounts
Manu Sporny:  Any questions?
Mary Bold:  Seems like a sensible approach.
Manu Sporny: 
  http://opencreds.org/specs/source/use-cases/#use-cases
Manu Sporny:  Jumping to use cases
Manu Sporny:  Use cases point out general use case, then use 
  examples to show how a specific use case can use it
Manu Sporny: 
  http://opencreds.org/specs/source/use-cases/#verifiable-claims
Manu Sporny:  Verifieable claims is a good place to start
Manu Sporny:  Reviewing verifiable claims as an example of how a 
  use case is set up
Manu Sporny:  Questions or comments on use case layout?
Chris McAvoy:  General question, is this how all wg / cg's layout 
  use cases?
Manu Sporny:  Yes and no…it's up to the cg / wg…everyone does it 
  differently
Manu Sporny:  The use cases fit the type of work, there isn't a 
  standard way to represent them
Manu Sporny:  Real question is, once the tech is done, can we 
  look back at the use cases and say definitively that we've 
  acheived the use cases…does anyone feel that if we do the tech 
  work around these use cases, will we know where to stop
Chris McAvoy:  That was great, thanks
Mary Bold:  Chris, can youg ive us guidance on the appraoch?
Chris McAvoy:  I actually like the approach, I was just curious 
  to understand how the W3C works. [scribe assist by Dave Longley]
Chris McAvoy:  I like the approach, just a general question about 
  how W3C works. My only concern is, from a development 
  perspective, it sounds like these are not set in stone. As we 
  move along, we can continue to adjust them. We're not entering 
  into a contract, as long as that's the case, this is a great 
  approach. [scribe assist by Manu Sporny]
Chris McAvoy:  From a development perspective... it sounds like 
  these aren't set in stone, as we move along we can continue to 
  adjust them. We're not entering into a contract so we have 
  flexibility to change it as we go. As long as that's the case I 
  think this is a great approach. [scribe assist by Dave Longley]
Manu Sporny:  Tech working groups have a requirement to build for 
  success…and manage the wg to keep it from going off the rails
Manu Sporny:  Also clarifies for ip protections
Manu Sporny:  Also allows the community to understand what could 
  conflict with existing ip, heads up to the lawyers about the 
  scope of the work
Chris McAvoy:  ::Thumbsup:
Manu Sporny:  Not a contract, not set in stone, assertion by the 
  group that this is what we intend to work on.
Manu Sporny:  Also gets the group on the same page
Manu Sporny:  Any other questions?
Manu Sporny:  Going to review the use cases
Manu Sporny:  Storage - can store a credential and a requestor 
  can request a credential
Manu Sporny: http://opencreds.org/specs/source/use-cases/#storage
Manu Sporny:  "Must" is in red, special language that denotes a 
  mandatory feature
Manu Sporny:  "Should" is an optional feature
Manu Sporny:  It's a choice by the cg / wg about whether or not 
  we use must or should
Manu Sporny:  Be careful about how we pick MUSTs and SHOULDs
Manu Sporny:  Interactive-transmission and non-interactive 
  transmission, design criteria and use case. you should be in the 
  loop if someone is requesting your credential
Manu Sporny:  That's an interactive use case
Manu Sporny:  Non-interactive is given an org the ability to pull 
  information whenever they need it
Manu Sporny:  With that ability the non-interactive org can pull 
  that credential whenever they want
Manu Sporny:  Need-to-know- share the bare minimum you need to to 
  be able to get the data to the website
Manu Sporny:  Need to know protects sender and receiver
Mary Bold:  Side point, when we use kids being 13, somewhere we 
  need to review access around the globe. us uses coppa. 
  internationally it's different. need to define "underage" as an 
  international term
Manu Sporny:  Agreed, need to follow up
Manu Sporny:  Composability - multiple credentials can be 
  combined to get you access to something
Manu Sporny:  Example, "two forms of identificiation to open a 
  bank account"
Manu Sporny:  Endorsement - multiple signatures…sort of
Manu Sporny:  Anonymity - pseudo anonymous identity, just 
  transmit specific bare minimum data
Manu Sporny:  Identity aliases - short names, @mentions, etc...
Manu Sporny:  Questions or comments?
Chris McAvoy:  Yes, one
Chris McAvoy:  Endorsement is a pretty loaded term
Chris McAvoy:  In the ed space there's a bunch of use cases 
  around endorsement
Manu Sporny:  Please send the info to the mailing list so we can 
  discuss it
Chris McAvoy:  From a Badge Alliance perspective, endorsement is 
  a loaded term - so, can we add some stuff to that use case. 
  [scribe assist by Manu Sporny]
Chris McAvoy:  Ok, we can do that
Bill Gebert:  One comment on use case that includes use of SAT
Bill Gebert:  Would like to change it to gre or toefel
Manu Sporny:  Will fix that right now
Chris McAvoy: Mary: agreed, gre is a better example, +1
Manu Sporny:  Any other questions or concerns?

Topic: Start Discussing Roadmap Document

Manu Sporny:  Last item on the agenda, need to discuss roadmap 
  document to plot out what we think needs to be finished for this 
  stuff to hit a world standard bar…example, spec, implementations, 
  test suite, public review, etc
Manu Sporny:  Need to propose a timeline that isn't more than 3-4 
  years
Manu Sporny: http://opencreds.org/specs/source/roadmap/
Manu Sporny:  It's ok to propose this in parallel
Manu Sporny:  Proposal / drafty document of the roadmap (above)
Manu Sporny:  Draft doesn't include edu cases…need badge alliance 
  to fill that out
Chris McAvoy:  We're ok with that ;)
Manu Sporny:  Review of active collaborators
Manu Sporny:  Yes please, badge alliance would like to be put 
  into the active collaborators section
Chris McAvoy:  Thanks
Manu Sporny:  This roadmap won't be presented as anything 
  official at TPAC, people need time to digest and give feedback. 
  if there's tech / orgs / that need to be part of this, we need to 
  get them into the doc
Manu Sporny:  We have a body of documents that can be reviewed
Manu Sporny:  Please take these docs back to your colleagues for 
  review
Manu Sporny:  We will meet again before TPAC
Manu Sporny:  Any concerns?
Mary Bold:  Looks good
Manu Sporny:  Thanks all, closes the call.
