Agenda Review & Announcements

Matthew_Atkinson: SAUR to be published based on positive resolution to recent CfC, thanks to all for responses. More to come

Matthew_Atkinson: no response for any additional announcements

New Charters Review https://github.com/w3c/strategy/issues?q=is%3Aissue+is%3Aopen+label%3A%22Horizontal+review+requested%22

<Roy> https://w3c.github.io/webrtc-charter/webrtc-charter.html

roy: web RTC working group charter; this group mentioned in deliverables section - references MAUR

roy: also mention RAUR in liason section

janina: excellent, happy to have them mention MAUR, may be interesting new RQTF proposal, Collaborative AUR: CAUR but probably don't need to mention that in this charter, yet. They work will with us

<Roy> https://www.w3.org/2022/06/draft-ag-charter

Roy: Accessibility Guidelines (AG) mention APA in Working group section

janina: with functional needs moving into APA it is important that we continue to work with them; especially as focus shifts to WCAG 3 after 2.2 released;

MichaelC: since func. needs was moved into APA, it might be good to mention in liason that AG will be looking to FAST for func. needs. This group gets a lot of attention, do we want a broader review of the charter

janina: I like the idea of mentioning FAST and perhaps should mention maturity model as well

Fazio: agree to maturity model

<Roy> 2. https://github.com/w3c/strategy/issues/332

MichaelC: we should add a comment to the strategy issue for the charter to include FAST and maturity model

janina: those are two best practices that will be relevant to WCAG 3 but we do have other specs under development that will provide quantitive data that should be included: for example SAUG includes research that can be referenced. We also have WAI-ADAPT

<MichaelC> proposed add to comment ¨and collaborate on guidelines implications of APA´s AUR documents¨

janina: and add normative specifications

MichaelC: we will work on this and will see it in the list again to review the comments

A11y Review Comment Tracker https://w3c.github.io/horizontal-issue-tracker/?repo=w3c/a11y-review

MichaelC: all of the comments in this category are on one feature of one spec; CSS color spec and color contrast feature

Make color-contrast() candidates optional

<MichaelC> - issue: https://github.com/w3c/csswg-drafts/issues/7345

<MichaelC> - tracking: https://github.com/w3c/a11y-review/issues/125

color-contrast() syntax is confusing

<MichaelC> - issue: https://github.com/w3c/csswg-drafts/issues/7354

<MichaelC> - tracking: https://github.com/w3c/a11y-review/issues/124

It should be possible to specify the contrast algorithm for color-contrast()

MichaelC: provides the ability to select a color that is WCAG 2.0 color contrast compliant. Believe we should follow and review

<MichaelC> - issue: https://github.com/w3c/csswg-drafts/issues/7356

<MichaelC> - tracking: https://github.com/w3c/a11y-review/issues/123

color-contrast() should allow specifying multiple contrast algorithms that need to be satisfied

<MichaelC> - issue: https://github.com/w3c/csswg-drafts/issues/7357

<MichaelC> - tracking: https://github.com/w3c/a11y-review/issues/122

color-contrast() should take transparency into account

<MichaelC> - issue: https://github.com/w3c/csswg-drafts/issues/7358

<MichaelC> - tracking: https://github.com/w3c/a11y-review/issues/121

color-contrast() should distinguish foreground and background

<MichaelC> - issue: https://github.com/w3c/csswg-drafts/issues/7359

<MichaelC> - tracking: https://github.com/w3c/a11y-review/issues/120

color-contrast() should support ranges of candidate colors, not just discrete color candidates

<MichaelC> - issue: https://github.com/w3c/csswg-drafts/issues/7360

<MichaelC> - tracking: https://github.com/w3c/a11y-review/issues/119

color-contrast() default algorithm

<MichaelC> - issue: https://github.com/w3c/csswg-drafts/issues/7361

<MichaelC> - tracking: https://github.com/w3c/a11y-review/issues/118

Matthew_Atkinson: I have reviewed this issues; Concern that we know the contrast algorithm is going to change and don't want css to diverge from WCAG;

MichaelC: This issue has been raised and is include within the list above. Believe we need to pay attention to this. Will keep this open.

janina: is this still a working draft?

MichaelC: believe it is an early draft

janina: we should advise Silver WG about this so co-chairs of that group can help review as part of their process

Matthew_Atkinson: believe I will complete my review and then APA would have a CfC to file a comment but that doesn't seem necessary since issues have been filed by other; Should we still file an official APA comment

MichaelC: agree that Matthew_Atkinson completes his review and drafts a comment for APA to review and determine best action; If our discussion in APA concludes there are serious problems we might take a different strategy to build a case and file

janina: there is still significant work for silver to research and update contrast algorithm so want them aware

MichaelC: believe low vision task force is the better place to focus attention

Matthew_Atkinson: want to make sure time scale of a few weeks to file comment is okay

MichaelC: plan is for CSS to move to CR in a few months - so we shouldn't dawddle

Matthew_Atkinson: we filed a comment about SVG native not providing a way to alternative text, is there follow up for that?

Matthew_Atkinson: issue was filed in SVG WG tracker, the people working on spec may not be following the issues closely. We need to wait for a response. Can discuss at APA planning call

<MichaelC> - tracking: https://www.w3.org/WAI/APA/wiki/Verifiable_Credentials_Data_Model_1.0

Task Force & Deliverables Updates


Lionel_Wolberger_: look into REL entity;


Fazio: presentations at upcoming ICCHP conference in Italy; there is a SC under dev that addresses mental health; need more research into cognitive and technology and effects


PaulG: nothing new to report; may not have a meeting


janina: major news: remote meetings nearing completion; waiting for comments from EO

Lionel_Wolberger_: tracking closely the trend towards password-less login; basic standpoint of APA has been that need to offer dual methods for authentication / biometric alternatives. When two people involved and there is a 3r party: deaf person with an interpretter; someone with a caretaker. There is also fiduciary considerations for custodial relationships

Fazio: as part of mental health progress we want to create a document for guardianship issues which mirrors what Lionel_Wolberger_ was sharing

Lionel_Wolberger_: yes 3: guardian ship, caretaker, interpretter

Matthew_Atkinson: sounds like great work in 2 different groups

maturity model

Fazio: no new news other than we are working in github

<Fazio> connect with COGA on the caretaker and guardianship
