Actions Review (Specs)
[10]http://www.w3.org/WAI/PF/Group/track/actions/open

     [10] http://www.w3.org/WAI/PF/Group/track/actions/open

   Janina: I'm in the middle of media. It's a long spec.
   ... I need to tell them that I'm working on it still. I'll do
   that today.

   MC: That would be a good idea.

   action-1615

   <trackbot> action-1615 -- Janina Sajka to Review media capture
   and streams [11]http://www.w3.org/tr/mediacapture-streams/ --
   due 2015-05-06 -- OPEN

     [11] http://www.w3.org/tr/mediacapture-streams/

   <trackbot>
   [12]https://www.w3.org/WAI/PF/Group/track/actions/1615

     [12] https://www.w3.org/WAI/PF/Group/track/actions/1615

   MC: There's a bunch of actions that are not due yet.
   ... Aside from media capture streams, there's nothing else
   under spec review.

new on TR [13]http://www.w3.org/TR/tr-status-drafts.html#tr_LCWD

     [13] http://www.w3.org/TR/tr-status-drafts.html#tr_LCWD

   MC: Everything else is due 27th or 29th
   ... Canvas 2D context is in last call.

   Janina: We're famailiar with that via HTML A11y task force.
   ... Rich is on top of that.

   <MichaelC> [14]HTML Canvas 2D Context

     [14] http://www.w3.org/TR/2dcontext/

   Janina: We were expecting this publication. We had some
   language changes last minute.
   ... I'm not sure if those changes made it into last call.
   ... We'll continue debugging the two implementations.
   ... Then we'll have full support, including hit regions.

   MC: About the CR, this is under the old process where it cannot
   easily change.
   ... That means we need to do things in last call.

   FE: Rich told me hit regions was implemented in Chrome and
   Firefox.

   Janina: I think both are amenable to bug reports.
   ... And we'll continue to manage this in the HTML A11y task
   force.

   MC: So we don't need an action in PF?

   Janina: No

   MC: They do not provide a last call due date.
   ... That means we don't know when they'll go to CR.

   Janina: I'll remind Paul to state that.
   ... I don't think we want the spec to change in CR, but do want
   it to be long enough to catch bugs.

   MC: It cannot exit CR unless it passes.

   Janina: I'm talking about bugs in implementation; not the spec.

   MC: CSS flexbox is up for last call.
   ... I believe we've reviewed it before. I know we've had
   concerns.

   <MichaelC> [15]CSS Flexible Box Layout Module Level 1

     [15] http://www.w3.org/TR/css-flexbox-1/

   MC: I'm not sure if we have anything to comment upon at this
   time.
   ... Candidate recommendations.

   RS: Bo is participating with the CSS group and is on top of
   this.

   <MichaelC> [16]TTML Text and Image Profiles for Internet Media
   Subtitles and Captions 1.0

     [16] http://www.w3.org/TR/ttml-imsc1/

   MC: I think we took a look at TTML Text and Image Profiles for
   Internet Media Subtitles and Captions 1.0 at the last CR.
   ... If they're in CR, there are presumably substantial changes.
   ... But I don't see a list of what they are.

   Janina: Would we be out of line to request a list of changes?

   MC: It wouldn't impact this publication.
   ... In general, I'd like to establish some best practices for
   review.
   ... They've made some changes with respect to frame rate
   synchronization.
   ... There's some editorial edits here and there.

   <Gottfried> I am trying to get in. But it says i am the first
   participant on the conference.

   <janina> Gottfried: We're on Webex: 647 857 439#

   MC: The initial value of text align should be center; before it
   didn't have a default value.

   <Gottfried> What URL?

   MC: Everything else looks like clarifications.

https://mit.webex.com/mit/j.php?MTID=m6e3f82ceee1b44268fd496d928c40001

   MC: Agreed that we don't need to review this?

   Janina: I don't think we need to review it.

   MC: Web Notifications

   <MichaelC> [18]Web Notifications

     [18] http://www.w3.org/TR/notifications/

   MC: This one is under the new process.
   ... I have the sense we've looked at this before. I don't
   recall if we had concerns.

   Janina: We did, concerns about an icon.
   ... But I think we backed off.

   MC: Reads from spec.

   Janina: I think that was the result of our comments.

   MC: There's no obvious ChangeLog.
   ... Three specs from us and two from HTML which use "ARIA" in
   their titles.

   Janina: We got review on the Notes on using ARIA in HTML.

   MC: The names of the two documents confuses me.

   Janina: Both are Steve's.
   ... The Notes document is basically best practice.
   ... There was quite a lot of discussion on list. Everyone
   approved publication.
   ... We need to be sure Notes and the ARIA Authoring Practices
   remain in sync.

   MC: I see this is REC track. Is that correct?

   Janina: No.
   ... Action me to point this out.

   <MichaelC> ACTION: janina to file comment on Notes on Using
   ARIA in HTML [19]http://www.w3.org/TR/aria-in-html/ that it
   should not be on the Rec track [recorded in
   [20]http://www.w3.org/2015/05/20-pf-minutes.html#action01]

     [19] http://www.w3.org/TR/aria-in-html/

   <trackbot> Created ACTION-1641 - File comment on notes on using
   aria in html [21]http://www.w3.org/tr/aria-in-html/ that it
   should not be on the rec track [on Janina Sajka - due
   2015-05-27].

     [21] http://www.w3.org/tr/aria-in-html/

   MC: There is now a means to publish more frequently via a new
   automated tool.
   ... The current version of this tool doesn't yet support
   non-REC-track documents.
   ... The tool should allow NOTE-track documents to also be
   published.

   Janina: Did they even think about it?

   MC: Yes, there's documentation stating that you cannot
   publishing NOTE-track stuff.
   ... Which is why I haven't moved us to that process yet.

   Janina: ARIA in HTML is the breakout of the section that talks
   about ARIA conformance.
   ... We had a lot of discussion about not having joint ownership
   of this document.
   ... And that document is on the automated process, and it is
   REC-track.
   ... We need to proactively review it from time to time now as a
   result.
   ... This is a coordination question we haven't talked about
   yet.
   ... If the group splits, the review working group would need to
   stay on top of things remaining in sync.
   ... And it will be up to the ARIA group to decide about joint
   ownership or not.

   MC: There are two other docs that are working drafts.

Community Groups [22]http://www.w3.org/community/groups/

     [22] http://www.w3.org/community/groups/

   MC: I had gotten a month ahead of our three-month advance.
   ... So we don't have any new community groups to look at as a
   result.

ARIA.Next Items--Extension Mechanism

   Janina: Rich, we have an extension definition.
   ... And we want a formal consensus?

   <janina> [23]https://www.w3.org/WAI/PF/wiki/ARIAExtensions

     [23] https://www.w3.org/WAI/PF/wiki/ARIAExtensions

   RS: We ran into an issue with Digital Publishing.
   ... We need to be able to extend ARIA without impacting ARIA
   core.
   ... So the Extensions proposal allows other groups to write an
   extension module.

   <richardschwerdtfeger>
   [24]https://www.w3.org/WAI/PF/wiki/ARIAExtensions

     [24] https://www.w3.org/WAI/PF/wiki/ARIAExtensions

   RS: Shane and I worked on this (link above)
   ... Anyone can start working on an extension.
   ... This is for 1.x. We don't yet know what we're going to do
   about ARIA 2.x.
   ... (Reads from document linked above)
   ... I don't know what will happen after the chartering.
   ... We may have one in development like ARIA 1.1, which is
   maybe in draft form. We need to be sure it's published on the
   TR list.
   ... (More reading from document)
   ... The ARIA group might want to incorporate some roles into
   the main spec, like Chapter.
   ... The other thing that will be required is a REC-track
   mapping specification.
   ... The important part is your extension cannot break ATs or
   interfere with other mappings.
   ... Are there any concerns about this?

   CS: I still need to write up the non-role-related extensions.

   RS: We're going to present this to the HTML Working Group
   tomorrow.
   ... I wouldn't worry too much about this now.

   Janina: We want to formally adopt this.
   ... This is version 1.0. We can always make a 1.1.

   CS: My concern is that 2.0 is going to be done as a set of
   modules.

   RS: If we have to tweak the process at some point, I don't
   think that's a problem.

   Janina: And this is for ARIA 1.x.

   CS: So you added the bit about it being for 1.x?

   RS: Yes.

   CS: I'll give it a quick read and send any concerns to the
   mailing list.

   Janina: Should I wait for this call to complete for a CFC?

   <richardschwerdtfeger> (hand-wave about versions and
   synchronization - TBD).

   RS: There's a statement from Shane about "hand wave" (text
   above)

   MC: What's to be determined is how we implement that.
   ... Does the ARIA spec say how to make extensions noramtive?
   ... Does the ARIA spec gets published with the extension
   incorporated into it?

   RS: I think that depends.

   Janina: It already says you could go either way with that.
   ... We don't have a mechanism on the engine end to implement
   only parts of things.

   CS: Not every browser is going to do every extension.
   ... For instance, if DPUB becomes a recommendation, why would
   browsers implement that?
   ... And it seems weird that failure to implement DPUB would
   make you non-compliant.

   RS: All DPUB readers are based on web engines.

   CS: If someone does an extension spec for scientific equations,
   would that mean your browser is not compliant?

   RS: Ah, no.
   ... You have to define a mapping, and have two implementations.
   ... A host language might not implement a module.
   ... For instance I don't think SVG would implement DPUB.

   MC: I do think the wording of item 4 is problematic.
   ... I read it to mean conformance equals ARIA plus all modules.

   CS: Yes.

   RS: Do you have suggested wording?

   MC: I don't have a single sentence.
   ... I think we need to make it clear that you can still conform
   to ARIA core.

   RS: Things that are not in ARIA core would be considered
   optional.

   MC: We say all roles are normative.

   CS: Conformance needs to be separate.

   RS: That's what I mean by optional. Browsers don't have to
   implement it. But you need two implementations.

   MC: What's not called out in this wording is if the extensions
   are in the REC track, their conformance is non-optional.

   CS: ARIA DPUB, for example, should be optional with respect to
   conformance to ARIA core.

   Janina: I think we'll be happiest if implementation of
   extensions is optional.

   MC: We need to be sure to include stakeholders.
   ... For instance, we'd be unhappy if longdesc were viewed as
   extensions.

   CS: I'm not worried about REC; I'm asking about my browser
   being compliant.

   Janina: Since this is not hammered out, it's not ready for CFC.

   RS: If the browser vendors don't implement the mappings, that's
   going to be a problem.

   CS: The concern is the never-ending addition of new things to
   ARIA.

   RS: Maybe I can word this differently.
   ... I think what Cynthia is saying is I've got a project
   schedule and now there's a new module.

   CS: Right.

   MC: And the ability to say IE is not a DPUB reader.

   CS: If there were ARIA molecular browser, I wouldn't expect
   everyone to implement it.
   ... We don't have molecular biology in the accessibility APIs.

   Janina: We may have lots of specialized extensions.

   CS: I agree that a path for specialized applications is an
   important thing.

   RS: So we need to tweak that bullet.

   CS: Yes, I want to say compliance to each extension is a
   separate thing.

   RS: I will figure out how to word this.

   Janina: Maybe things that are prefixed are optional and
   non-prefixed items are required.

   RS: So we're going to probably need another round of this.
   ... I hope it won't take too long because DPUB is waiting for
   this.
   ... Maybe we get what people agree to in this version.

   CS: Maybe an editorial note regarding things we're still
   discussing.

   RS: I'll note that on the bullet.

   Janina: I think we're ready for tomorrow's meeting.
   ... I've invited everyone from PF, DPUB, and HTML.
