Topic: Introductions and Reintroductions
Christopher Allen: Anybody new? Or re-introductions?
Drummond Reed: Chief trust officer at evernym, leading role at
Sovrin foundation, working on the DID specification with many
people on this call
Abbas Ali: Me
... verifiable claims with DIDs and all the infrastructure that
it will require.
Drummond Reed: Abbas, welcome
Abbas Ali: Works at R3, joined the group looking at verifiable
claims for the purpose of onboarding at banks.
... interested in partnerships with identity service providers
Christopher Allen: That ends introductions, thanks.
Topic: Agenda Review
Christopher Allen: Due to approve the new name mission statement
... completed a first draft
Ryan Grant: https://goo.gl/sNs2vl
Christopher Allen:

Christopher Allen: For those participating in the Face2Face at

Christopher Allen:
https://www.eventbrite.com/e/rebootingweboftrust-design-workshop-v-fall-2017-in-boston-area-usa-tickets-34984665075
... receiving topic proposals in the topics dir of the repo
Christopher Allen:
https://github.com/WebOfTrustInfo/rebooting-the-web-of-trust-fall2017
... Manu submitted a primer on verifiable claims, Drummond
working on one for DID
Kim Hamilton Duffy: New CCG site: https://w3c-ccg.github.io/
Christopher Allen: https://w3c-ccg.github.io/
Christopher Allen: The URL https://w3c-ccg.github.io/ is our
primary github.
... If it seems to be missing stuff, contact kim, chris or manu
Christopher Allen: https://www.w3.org/community/credentials/
... This secondary page
https://www.w3.org/community/credentials/ has better visibility
in Google
... but due to its less flexible UX/UI, is more limited in the
info that is there.
... Issue: add a "call to join the group" to the w3.org
homepage.
Christopher Allen: https://w3c-ccg.github.io/meetings/
Kim Hamilton Duffy: We have a "Weekly Meeting Information" in the
sidebar of the W3C site
... this group inherits various meetings groups and efforts
going back bast 2013.
Kim Hamilton Duffy: Let me know if we need a better link name to
make that more actionable. I can reorder these items as well
Dave Longley: CCG was part of the Web Payments CG prior to 2014
(it split out from that group in 2014)
Lionel Wolberger: Definite improvement over the past 3 weeks or
so [scribe assist by Manu Sporny]
Kim Hamilton Duffy: Committed to continuing to improve the
sites, open to any and all suggestions.
Topic: Digital Verification Community Group
Christopher Allen: Digital verification community group had
crossover with Credentials Community Group.
... Chris and Kimh co-chaired both
... Digital Verification Group has value having its own repo
and separate meetings devoted to certain issues such as selective
disclosure and data minimization
... This DVG is "under" this CCG
Nathan George: +1 To a task force meeting to introduce
Sovrin/Hyperledger Indy's CL-sig implementation (and try to get
our crypto folks more involved)
... Chris open to thoughts on whether DVG is a group, or task
force, etc.
Manu Sporny: +1 That DVG be subtaskforce to the CCG
... one motivation for having it separate was quasi-political,
due to strong pushback from W3C regarding crypto
... strong opinion there, that a security/crypto group needs to
be mostly 'insiders' from those security/crypto groups
... the web crypto group both invited DVG in (you should be
here) and then did not prioritize its agenda (...we don't want to
talk about that stuff here...)
... so DVG remains with its crypto focus
... CCG should probably AVOID pulling DVCG work items onto its
agenda.
... that said, we have people now who understand crypto (chris,
lionel, yan, sovrin people)
Christopher Allen: More motivation to go to task force language:
gives us scope to mention these more technical things on the
master page for the community
... Prioritization of these technical items should be done by
the CCG first and go forward from there
ACTION: KimHD to send out proposal for how CCG and DVCG work
together.

Topic: Mission Statement
Manu Sporny:
https://docs.google.com/document/d/1kxm6yGnGAVgNTLMYft_cz2zW3c1AE8uSCy4i5A6OhG8/edit#bookmark=id.3fsalpuqeupm
ACTION: KimHD to add subscribe button on our page, like "Join" on
https://www.w3.org/community/credentials/. Make sure patent
policy, etc is respected
Christopher Allen: Walking through the items on the Google doc.
... Discussion focusing on "creation, storage, presentation,
and verification"
... no objections.
Christopher Allen: Focus on the unique nature of credentials or
identity-bearing instruments, and the proofs involved, should be
called out
Kim Hamilton Duffy: +1
Drummond Reed: I agree that having the term "verifiable claims"
in the mission statement would be good
Drummond Reed: I agree that "verifiable claims" has become a term
of art
... verifiable claims is a term of art that has caught on
(though verifiable credentials does seem more cogent)
Manu Sporny: Subtle point, a claim is not verifiable.
... a credential is verifiable
Moses Ma: Is there a distinction between verified vs
authenticated?
Drummond Reed: Leave self-sovereign identity in
Manu Sporny: Moses, yes, there is a distinction... you must
verify someone before they're authenticated (but even this
definition is arguable)
Manu Sporny: (And highly technical)
Moses Ma: Manu, should claims be authenticated as well as
verified?
Christopher Allen: After word by word discussion, we converge
on:
The mission of the Credentials Community Group is to explore the
creation, storage, presentation, and verification of credentials.
We focus on a verifiable credential (a set of claims) created by
an issuer about a subject—a person, group, or thing—and seek
solutions inclusive of approaches such as: self-sovereign
identity; presentation of proofs by the bearer; data
minimization; and centralized, federated, and decentralized
registry and identity systems. Our tasks include drafting and
incubating Internet specifications for further standardization
and prototyping and testing reference implementations.
Drummond Reed: This draft is good.
Manu Sporny: Moses, no - authentication is separate... it happens
later
Manu Sporny: (Or rather, it's complicated and we shouldn't muddy
the waters by bringing "authentication" into all of this.
Christopher Allen: Issue of long-lived credentials. The
challenge is significant due to expiration or lost keys.
Drummond Reed: I agree that long-lived credentials are important
... Other longue duree challenges: the school changed its name
... Some related solutions include discovering proofs that were
valid at time X etc,
... Refugees for example are forced to present claims that were
true in the past but are difficult to verify
... This group has access to very effective methods to address
these issues that other groups just do not have.
Moses Ma: Thanks, gotta bail!
