Actions Review

Only one action item left, on Judy

zakim take up item 3
User Requirements: Update RE Additional Disclaimer

Janina report last week to the HTML WG

so far no questions or comments

presentation went smoothly and well recieved

<silvia> +q

yes we can hear Silvia

<janina> Silvia, we hear you


Silvia - Q: did janina speak about a process about moving content into the
W3C Draft

regarding technical issues

janina - pointed the chairs to the checklist and user requirements, and
indicated that we are very close to analysis of the different time-stamp
Actions Review
Proof of Concept Demos; Extended Descriptions from NCAM

Janina - in conversation with Geoff about proof of concept videos

having examples. even in older formats is useful - Geoff has a number of

Janina - just want to confirm that these would be useful, even if using
older tech

Eric - useful to have the rendered output so that we can see what it is
supposed to look like

and then perhaps the individual pieces so that we can re-create in current
technologies as well

will request thta of Geoff

zakin, take up item 5
Time/Track Formats

Janina, can we bring over some of the WHAT WG language without specifying

<silvia> +q

seems that via email list that it would be possible but with some work

asking if Sean/Silvia/Eric could work on this?

Sean: concern is over patent Policy

copyright concerns

so what we need to identify the edits we need to have made, ask ian/WHAT
WG to make those changes, then move into the W3C spec

so suggest we produce a list of changes and request the editor make the

Silvia: a little worried about us going ahead and making radical changes
to ian's work

suggest that we are concerned about the explicit mention of WebSRT

and ak editor if he would be prepared to remove specific reference to
WebSRT and instead express the ideas in a more abstract way

so that WebSRT could be one of the text formats, but others would be
easily plug-in instead

Sean: we could simply ask ian to do thi, and then see what his response is

Judy" believes that we need to involve PHL into this conversation

it may be a bit trickier than this

fair amount of discussion surrounding document license issues

so we need to ensure we are synched up with that dialog


Judy willing to take action item to see what is happening at W3C right now

Sean: one approach is to work in the wiki, and have ian review that and
then adopt

using the wiki a safer route

re: IP issues

JF - ian will be on vacation soon

Judy will investigate timing issues

Janina: 2 possible approaches. start with Silvia's text and ask for bugs
against it

of prefer that if Ian takes out the specific WebSRT text 9and provide a
list of where) then we can perhaps move more quickly

Eric: sounds like we need to hear back from judy if there are any
political or legal blockers
... if we revert back to the work that Silvia did, it will be a lot more
work, whereas if we can get ian to work with us it will take much less

janina: so paht is to await Judy's report back on policy/legal concerns,
after which we sent a request to ian
... hope that we can get this rolling before next weeks call, with
appropriate CC's on the note

more TBD

<scribe> (New Agenda item)
prioritizing user reqs for user agent work

<sean> +q

Eric: wants to stress his concerns over prioritization of the technical
requirements, as if we leave it to browsers to work out that list it will
be a dis-jointed effort

<Judy> ack si, ack ju

Notes thta JF has started working on that

Sean: perhaps add another column to the table

authors will want to meet WCAG, so have a column thta maps to WCAG a, aa,

so that we also have an idea of which issues impact on WCAG

thta would help with a prioritization

Judy: think that what Sean is proposing (tying to WCAG) is an interesting
way of looking at it

(notes that they are called conformance levels)

this will also remove some hesitation as these have already been vetted

understands the need to help guide the development process

Judy: tying it to the substance of the WCAG criteria

Sean volunteers to take a run at adding it to the list

Eric: we need to ensure that the core reqs are consistent across all
browsers, as this will encourage authors to actually use this stufff

Seems that the attendees are in agreement that this general thrust is
important, and that mapping to WCAG is a way forward

Silvia: what we need to determine the actual technologies which is almost
at a higher level

silvia looking at 3 immeadiate needs

inclusion of tracks

interface to multi-track files

ensure that we can do the navigation requirements

(ie navigation coordination)

when we figure these out, they will answer many of the questions

we started with a bottom up list, now we need to start with a top down
review of technologies, at which point we will reach a middle ground

thinks tracking Must/should.may as well as tracking WCAG A/AA/AAA is

but wants to see a programic approach as well

Janina: asking Silvia if WHATWG is understanding some of our more vexxing

silvia - they seem to be, but will need to be tested - they are moving in
that direction, but it is too early to tell

ACTIO: Sean to map WACG A, AA, and AAA against our checklist

<scribe> ACTION: Sean to map WACG A, AA, and AAA against our checklist
[recorded in http://www.w3.org/2010/09/15-html-a11y-minutes.html#action01]

<trackbot> Created ACTION-60 - Map WCAG A, AA, and AAA against our
checklist [on Sean Hayes - due 2010-09-22].

Eric: not necessary to call out difference between mobile and desktop

not saying it will be easy work, but not overly concerned

Silvia; audio processing on a mobile device is not really that much -
concurs with eric, no real technical restrictions

this will be a place where competition between browsers will be a good

<Zakim> janina, you wanted to ask silvia whether what has considered the
use case where text descriptions exceed primary resource timeline
next meeting
Technical Requirements Prioritizations and Dependencies

thank you

<silvia> scribenick: silvia

jf: there are still many holes, but we're making progress

. had a conversation with Mike Smith and asked the engineers there to
provide input

. input about the different types of technologies that we can add

. also, I took a stab and the must/should/may column

. ppl with extensive knowledge on a11y requirements should chip in

. hopefully it will help Eric's concerns, and the WCAG work will add to
that, too

janina: can you take us through the ones that are mays?

jf: see http://www.w3.org/WAI/PF/HTML/wiki/Media_Accessibility_Checklist

. DV-3,5,6,7,8,10,11,14 are shoulds

. DV-9,13 are mays

janina: I don't think you can legally make DV-14 a should :-)

jf: . TVD-2 cnt, TVD-3, TVD-4 are shoulds

janina: is this taking us towards where we should go?

. also how will we resolve conflict within the group here on opinions on

kenny: I don't have write access to the page actually

michaelc: fixing it now

<JF> ACTION: Michael Cooper to grant Kenny Johar to write ability to the
wiki (specifically at
_Requirements_Prioritizations_and_Dependencies) [recorded in

<trackbot> Created ACTION-61 - Cooper to grant Kenny Johar to write
ability to the wiki (specifically at
_Requirements_Prioritizations_and_Dependencies) [on Michael Cooper - due

kenny: I can email my input to the must/should/may judgements

jf: I was using my gut feel rather than WCAG to judge this

. I'm also considering engineering needs in this

. I'll wait for kenny's email and take a crack at the system requirements,

. could other make a review, too, and highlight areas that are contentious

eric: the right way to do this would be with email

janina+silvia: I think so, too

jf: we still have some holes on the technologies

silvia: I will fix the holes in the technologies

<JF> Silvia will continue working on the technology requirements

janina: last week we agreed that Kenny would do the structural navigation

silvia: no problem

janina: in summary, we should have a complete document by next week

<JF> Want to ensure that the technology column is done in abstract terms,
and to date outisde assitance has been technology specific (Use SMIL,
Real_Audio, etc.)

. and we should have a discussion on email with the prioritisation

jf: can we please make sure to have [media] prefixed in the email and can
we make sure to have an email per item, so we can have a focused

janina: ok, though that may lead to a lot of threads

. so have in your email e.g. [media] DV-12 - comment

<JF> Janina: believes we are done

. as the topic

<JF> any further question s?

<scribe> scribe: JF

janina, wrapping up - thanks to all
