<JF> zakin, who's here?

JF: We had an interesting call yesterday, revisiting the poster alt issue (now referred to as pause video).
<MikeSmith> we are now using the term "paused media" to refer to what we had been called the "poster alt issue"
JF: We were fortunate to have
Kelly Ford, Jim Allen and Jean Spellman join us. We got some
possible ideas on paper on how to solve this problem. We wanted
very clear understanding of the UX.
... We didn't come up with a definitive result, but I think the UA people have a more clear understanding of the issue we're grappling with. I emailed out an update of the issue to the HTML A11y list.
... The concern with ARIA being a CR is that it's hard to re-open it at this stage.
... The difficulty is that to use ARIA means that the description is flattened out, without semantic structure.
... The way aria-describedby works is to reference an id that could be on a paragraph, div or something else.
... When the fragment string is pulled back, any HTML contiined is returned as flat text.
MS: That sounds broken to me.
JF: Correct. It's something that
hasn't been fully clarified in the ARIA spec, but it's in
... So the behaviour hasn't been defined anywhere, and so the question becomes *where should it be defined?
MS: We could let things proceed with ARIA, and try to fix things at a later point.
JF: We could, but if the browsers
cannot interpret the fragment strig properly, our solution is
dead in the water.
... Another possibility is to try and get it into UAAG 2.0 perhaps.
MS: I'm less familiar with the UAAG spec and what it normatively definess...
JF: I've posed the question to Jim and Jean. Judy, can you shed some light?
JB: You've explained it well John
in terms of where we want to be, but I would least like to
disrupt a spec that's in CR.
... I would prefer it if these solutions were addressed as definitively as can be.
JF: The place where we have a problem right now, is with the implimentation that browsers are doing.
MS: Someone needs to file a bug...
JF: I'd need to go and check, but I eblieve there may already be a bug.
MS: I'd file the bug, send an email to list and flag up with the people who represent browser vendors and ask for comment/feedback on the bug.
JB: We checked the status of
items being worked on, table summary was reassigned. There was
some discussion about the thread on the alternate proposal
that's expected on longdesc.
... Work is still pending on metaname generator and figcaption. The current approach on figcaption is to have the validator throw an author warning, and to draw up some use cases that exemplify the problem.
MS: It would be good to restart some of the discussion with the wider TF.
JB: I'm hoping to get something out o the list.
RS: We're looking at how we get the bounding dimensions of an object on your screen so a magnifier can correct it. We're trying to tie this into the hit testing we spoke about.
<MikeSmith> Paul Bakaus commented on the importance of hit testing
RS: We could do this by taking
the context for canvas and sub classing it with a drawing
object that has the same properties.
... Charles put out a proposal to suggest creating drawing paths and associating them with elements of the canvas sub tree. Frank suggested putting the bounds on the DOM elements, but we're trying to keep the same DOM that we have for the rest of the spec.
... Do we need to create issues for these things now? Is this the process for after last call?
... Should I reuse the same bug as before?
MS: Yes, then we have the context on it.
RS: Ian has asked not to be the editor of canvas, so who is the editor?
MS: We don't have an editor at this moment.
JF: I nominate Rich!
MS: Ultimately it's up to the chairs, the responsibility from here is on the chairs and they've been having discussions about it.
JB: I'm hoping the chairs are taking into consideration the benefit of having someone involved with the accessibility of this.
RS: I'd push to be co-editor in that case, not sole editor.
MS: The chairs will make an
announcement, it hasn't fallen between the cracks.
... The hit testing conversation doesn't seem to have progressed Rich?
RS: I'd like to see the browser vendors become more involved in this conversation.
MS: This is useful outside of the context of accessibility as well.
RS: Gettings thing done in CSS will take a long time.
JB: Perhaps those of us who intersect with Frank or David could encourage them?
RS: Defects have to be logged by 3rd Aug, is that right Mike?
MS: LC comments, yes. It would be good to get them in before then, but if we can't it goes back through the same process again.
RS: I'm seeing people asking bugs, are we really entering comments? What's the correct process?
MS: It depends on the purpose. We say bug because that what it's referred to in bugzilla.
MS recapping the aria-describedby content flattening issue.
<JF> Revised Timeline and New Bug Priority Policy - http://lists.w3.org/Archives/Public/public-html/2011Jun/0315.html
RS: I can check on that.
<JF> Expectations when adding the TrackerRequest keyword - http://lists.w3.org/Archives/Public/public-html/2011Jun/0316.html
JF: This is what we were talking
about yesterday on the media call.
... The key overview is in the email I sent to the list yesterday.
... We need to be sure the string retains the markup.
RS: The only time that can't happen is if the string is hidden.
JF: I'm concerned when we say
hidden... hideen to who? SIghted users or hidden from
... Is alt text hidden? I don't see it, it's in the DOM, it's not visible on screen.
RS: To do what you want to do, we'll need to do what we're doing with canvas. We'll have to make it available so the AT can process it.
JF: Rich, we really need you to help us with this conversation.
RS: I'll be there on the media
... What I'd like to see you do... if you want to hide the content, I would make it so it can be rendered visible as an option. That way you can have the reference, but once you rendere it... this would also help people with a learning disability, or people curious to see the text.
<MikeSmith> scribe: JF
Leonie: has started reviewing the spec and has started a wiki page
4.5.3 pre element has some issues
this was first identified by gregory
MS: don't recall the issue either
if there are issues there we should get them into the bug system
Leonie: the issue is that information that is conveyed via visual layout by using pre is not being conveyed to AT
MS: file the bug sooner rather than later
we can update info as it evolves
Leonie: the other issue is about the fig element
<MikeSmith> 4.5.13 on div
question is about using div is a core accessibility issue
<MikeSmith> "Authors are strongly encouraged to view the div element as an element of last resort, for when no other element is suitable. Use of the div element instead of more appropriate elements leads to poor accessibility for readers and poor maintainability for authors."
MS: this is a note very close to the top, it is more of an authoring guidance issue
JB: we should perhaps look at this more closely next week?
suggest adding it to next week's agenda
MS: as I look at this, I wonder what is the accessibility problem - needs elaboration
JB: thanks to Leonie for raising this, we need to look at this further
MS: we have been postponing Last Call spec review to top of agenda for next week
anyone who has taken an assignment please be ready for next week
MS: need to wrap up, anything else?
<MikeSmith> thanks everybody
