Topic: Agenda Review and Introductions

Dan Burnett: Any changes to Agenda?
Dan Burnett: Adding item, Pull Request discussion wrt. Revocation.

Topic: Status of Verifiable Claims WG Creation

Dan Burnett: Status of WG. Not much changed, some discussion about charter. Phil proposed change, unsure if it is necessary.

Topic: Status of Face to Face in March

Dan Burnett: The was a possibility of a F2F in March. Turns out 2/3 chairs can not make it. Burn sent a request to schedule the meeting and asked if anyone can attend. No reply. Time is close. Chairs want to know the feeling of people to attend.
Dan Burnett: Potential date is March 21st
Date for f2F is march 21st
This is for Chicago assoc with web payments meeting
Matt Stone: Need time to plan.
Dan Burnett: Issue is that someone new to the group needs time to plan meeting
Dan Burnett: Objections?
Manu Sporny: Perhaps we should delay a F2F
Manu Sporny: We brought up the VC WG up yesterday. Still possible to hold a meeting.
... as discussed with w3C in the past, we had the option for a formal meeting, but without chairs, difficult.
Nate Otto: Some more time between official word that we'll start and first face to face would improve chances of me being able to get my org to join W3C by the meeting.
... the question becomes, when should we have a meeting? usually 2 months after the w3c group. Brings us to the June time frame.
... the may not be a good time. we should do a doodle poll. and where, when.
Dan Burnett: We haven't discussed next steps. We don't have to wait until official, need feedback from w3c.
... as soon as it looks close and no longer discussing the charter then let' do doodle poll.
Matt Stone: To manu, comment. look for an invite from matt a request for suggestions for F2F this year.
... and if there are opportunities to tag on to other events.
ACTION: Matt send email regarding face-to-face opportunities in next 2-3 days.

Topic: Action Item Review

... need update data-model not use-cases
Nate Otto: A lot of jargon in use-cases. need to draw out more meaning
Manu Sporny: A while ago people volunteered. Nat, jonnycrunch. then we got into healthcare privacy discussion. Need explanation of privacy detail. but this wasn't the ask.
... we should have assigned specific details on point.
... we should ask specific direction for volunteers
Nate Otto: Perhaps if we have more conversation on github as issue
Nate Otto: Dig into specific ticket.
Manu Sporny: Next step - assign specific issue to volunteer, 1-2 paragraphs.
Joe Andrieu: Question - my understanding was to take on the coorelation ,,,, here are some issues regarding the spec. rather than language for the spec.
Manu Sporny: Was was asked was language for the spec. not more issues.
ACTION: Nate Otto will take Data Model issue #9 and #6.
... spec language. initial ask. we have blank spaces in spec.
... the spec is fine but is raises more issues.
... the ask . the text doesn't need to be perfect. we need something there.
