Notes

• IP and antitrust announcement.
• The primary goal of today’s meeting is to decide how to incorporate the feedback that we have received for our drafting document.
• Drummond noted that they are working on a new version of the “path diagram” that should add additional context. The updated images may require groups to update their references or descriptive text associated with those diagrams.
• Reviewed the feedback that came from Charlie Walton.
• We could use better framing / more of an introductory section. Drummond noted that the draft that Charlie reviewed did not have the full introduction that we now have.
• We should provide links for people to be able to get additional information on alternative health passes. Drummond noted that the overview narrative document will likely contain a “state of the market” section.
• “Phoning Home” would benefit from a sidebar or call-out to provide a definition for those who may not be familiar with it.
• Additional language in Problem #6 would help provide information on how this relates to the work done by VCI.
• Somewhere in the overall document, there needs to be an explanation of the rationale for the 30-90-180 timelines. Kaliya and Drummond will find a place for this (Overview / Chapter 2).
• We moved Problem #6 to the first spot. This can provide a better flow to the story.
• Reviewed comments provided by the general review, as well as other currently open comments.
• Drummond: Proxy credential issuers should support as many input formats as possible.
• We had a discussion regarding the use of proxy issuers and where they fit into the overall document. There are some recommendations for this in the “Information Security” section of the Security, Privacy, and Data Protection draft. We also need to discuss it here in our draft document.
• Wenjing noted that the recommendations and content across the different sections (i.e., drafts) should be aligned, if possible. Drummond suggested that this may be a good work project during the public review period.
• Part of the text in Problem #2’s description, per Riley’s suggestion, should be moved earlier in the section, as they aren’t really recommendations; they are background / justification.
• Drummond suggested that we wait for the new diagrams to help fix some of the shortfalls in Problem #3’s requirements and considerations section.
