Minutes for 2015-07-14

Gregg Kellogg is scribing.
Manu Sporny: Brendan is joining us today, intro later.

Topic: Introduction to Brendan Benshoof

Brendan Benshoof: I've not been able to join [scribe assist by Andrew Rosen]
Brendan Benshoof: I’m a grad student at georga state university. I work on distributed hash tables and making them do things they weren’t intended for.
… You have a black box labeled that, and I think I might be the one to remove the magic from it.
Nate Otto: That would be cool if you could make some magic real, Brendan. Nice to meet you.
Manu Sporny: We hang out on the #ipfs chanel, and a number of folks there are interested in decentralized hash tables and have been talking about stuff there for a while.
… Hopefully, Blame will be able to join us and help us there, happy to have you!
… That will help us have deeper discussions about decentralized identifiers.

Topic: Recruiting

Manu Sporny: I’ve been busy for the last week, but have been invited to speak at the Federal Reserve’s payment symposium. It’s an invite-only event with core-finanical folk.s
… They’re specifically interested in W3C and credentials. That puts a lot of weight behind what we’re doing.
… That would allow us to get more recruits in from govt and finanical services.
Eric Korb: We’re working on a project with IMS global; we’re using the JSON-LD format for credentials to express an extended transcript.
… We expect to demonstrate a prototype at “educause” in november.
Nate Otto: EDUCAUSE conference in Indianapolis in October.
… Mark Leuba is the chair of that at IMS Global.
… That will come a multi-purpose issuer to sign such documents, and a spec for describing a transcript in JSON-LD.
… This includes many open-source projects to describe this.
… I’ve also been asked to talk to an IMS quarterly meeting on AUgust 17th.
Manu Sporny: These are great opportunities, but a bit late for W3C’s needs.
Eric Korb: I invited Credly to invite us, and will follow up.
Manu Sporny: There’s a punch-list of about 100 W3C members that it would be great if you could help follow-up on.
Nate Otto: I’ve talked with Concentric Sky, and we’re going to do a review and have an answer in a couple of days.
… Badge Alliance is similar and should be able to give them an opinion shortly and hopefully get them to join.
Matt Stone: I’ve started a discussion with some sales people on the aclaim team. Parson has several clients that might also be good fits.
Manu Sporny: We may want to get some things produced while we’re waiting on recruiting.

Topic: Producing Documents

Brian Sletten: I have some time to work on docs.
Manu Sporny: I think we need to get back to producing documents. We do need more recruiting, and we’re not there yet, but we have other things to do.
… It’s going to be hard to convince W3C at the beginning of August without 15 more organizations.
… We need 30-40 at a bare minimum.
… We have 18 out of 47 right now.
… At the bottom is a simple form for them to fill out, or a verbal yes is fine too.
Eric Korb: I just filled it out for Accreditrust.
Nate Otto: Concentric Sky needs a technical review, and will decide after that.

Topic: Vision document

Manu Sporny: In the mean time, the folks not recrutiting can help on documents.
… We don’t have one yet, but the payments group’s could be a model.
… The doc is a quick 1-2 page. Perhaps Accreditrust/Pearson could help with this, and it should be quick.
Nate Otto: By take the lead on this document, you mean creating a "vision document" for credentials based on the template that the Web Payments IG has?
… There’s a bit at the top: “Web Principles” that shouldn’t need to be re-stated.
… Choice in where to store credentials, etc.
Eric Korb: We can contribute.
Matt Stone: I’d like to help too.
Gregg Kellogg: I can help with ReSpec formatting, if you just have text.
Manu Sporny: RichardVarn will also help.
… Deadline, beginning of August.
Nate Otto: Beginning of August is good.
Brendan Benshoof: Pull requests are made for this
Gregg Kellogg: We should put a skeleton ReSpec file in github [scribe assist by Manu Sporny]
Gregg Kellogg: From practical experience, I find that working on feature branches for these types of things might work well. [scribe assist by Manu Sporny]
Manu Sporny: What’s worked well is to work from a google-doc. At some point we’ll freeze it and move it over.
Gregg Kellogg: That's fine - but Github is designed for this sort of collaboration - but I don't want that to be a barrier - google doc, emails, whatever works for people, I'll edit. [scribe assist by Manu Sporny]
Nate Otto: +1 Open Credentials
Manu Sporny: We’ve been talking about “Open Credentials”, but maybe “Web Credentials”, or just “Credentials”.
Matt Stone: +1 Open Credentials
Matt Stone: Or at least -1 Web Credentials :)
Manu Sporny: This is where the group keeps it specs:

Topic: Use Cases

Brian Sletten: I’ll move it over to ReSpec in the opencreds repo.
Manu Sporny: There are some comments to resolve.
Brian Sletten: I’ll tak a pass at encorporating the comments.

Topic: Capabilities

Nate Otto: Thanks, bsletten -- feel free to ask me too if you have any questions on on of my comments.
Manu Sporny: The WebPayments group came up with the concept of a “Web Payments Architecture”.
… A credential system should be able to … (as basic capabilities).
… In the payments group we broke them down into high-level groups. E.g., there is a core-security part, another is “trust and identity”.
… Everything else has to do with payments, we would probably have stuff specifically for credentials.
… We don’t have any conent for this yet, and it will be a good month of effort.
Brian Sletten: Would August be soon enough to get started?
Manu Sporny: A stub now would be good.
Matt Stone: I can help too.
Brendan Benshoof: I can help jump in too.

Topic: Roadmap

Manu Sporny: This document’s pretty old (but not terrible).
… The web payments group took a different approach.
… The purpose of the roadmap document is to be crystal clear about what a WG would work on.
… It should have a very narrow scope, and specific use cases, capabilities and documents to be produced within the group’s timeframe.
… This document tries to make this clear, and shows that there is a near-term end to the work.
… I suggest that we lay the roadmap out in a similar way to the Web Payments group, preserving our current diagrams.
… I’ll volunteer to align these two documents.
Eric Korb: Is there a way we can produce a document that shows the documents we need to produce?
Manu Sporny: That’s on today’s agenda.
… The roadmap will reference the documents the group will publish.
Gregg Kellogg: The group would specify the documents they want to create in the roadmap. [scribe assist by Manu Sporny]
Manu Sporny: These documents help rally different groups together to go in a single direction.
… The goal for next week should be to have stub-documents set up for all of these documents, and get updates on progress.
