Discussion on ISSUE-85 with TAG members

<paulc> paulc: No progress on this item. We will continue to track it.

<paulc> paulc: if there is no progress by the TPAC F2F then I will request the TAG members responsible to attend the F2F.

Media Task Force F2F meeting, TPAC, Sapporo, Japan, Oct 29-30 2015

<paulc> See wiki agenda: http://www.w3.org/wiki/HTML/wg/2015-10-Agenda (under construction)

<paulc> paulc: I expect an agenda outline this week based on today's EME meeting and next week's MSE meeting.

<paulc> paulc: no questions from the floor

<markw> I’ll be there

<davide> nope

<jdsmith> paulc: Joe Steele is coming as well.

<jdsmith> jdsmith: I am coming too.

<scribe> scribe: joesteele

ISSUE-97: Algorithm references use title case inconsistently

New Issues

Issue 97

paulc: not sure whether this is just editorial

ddorwin: not self assigned yet — would like input on options

paulc: if someone could weigh in that would be good

jdsmith: I will take that — have a preference for all caps

ddorwin: that works for me

https://github.com/w3c/encrypted-media/issues/97

ISSUE-96: Consider reasons other than Distinctive Identifier in the steps of the Consent Status algorithm

<paulc_> paulc: Issue has a solution and David has self-assigned.

ISSUE-41 and ISSUE-53 - Initialization Data issue cluster

<paulc_> See Paul's update/question: tps://lists.w3.org/Archives/Public/public-html-media/2015Oct/0001.html

<paulc_> See Paul's update/question: https://lists.w3.org/Archives/Public/public-html-media/2015Oct/0001.html

joesteele: I responded to that

https://github.com/w3c/encrypted-media/issues/41

<paulc_> Issue-41 response from Joe: https://github.com/w3c/encrypted-media/issues/41#issuecomment-145740508

paulc: what is the plan going forward here?

… 52 was blocking 41.

joesteele: couple of issues raised

… David mentioned an interop issue

… And in the issue the need for a use case was mentioned

… I added the use case — we should discuss the other

paulc: the point about interop issue is that implementations might change — but spec is not final yet

ddorwin: however this is a late feature and would delay last call. Would prefer to focus on the 40 other bugs first

… figuring out whether this is useful would take time away from other features

… not sure whether this is useful and or broad enough to warrant this

paulc: are you saying that about both 41 and 53?

ddorwin: yes

paulc: so you would like these resolved later? please put in the bug then

ddorwin: ok

markw: I believe issue 41 is relatively simple and will not cause really any additonal work

… 53 is bigger and would require more thought. We might still want to to it for LC but it's a different matter from #41

… but we could do 41 now

paulc: david when you respond you should explain why you think 41 would delay us

Outstanding pull requests

Issue 80 and 81

https://github.com/w3c/encrypted-media/issues/80

https://github.com/w3c/encrypted-media/issues/81

paulc: most of these are pull requests from Mark

<paulc_> https://github.com/w3c/encrypted-media/pull/87 is the associated PR

… one of the editors needs to step up and review

jdsmith: I can review that

ddorwin: I can look also but lower priority

Issue 82, Pull request 89

https://github.com/w3c/encrypted-media/issues/82

https://github.com/w3c/encrypted-media/pull/89

paulc: David or Jerry can one of you take this?

ddorwin: that makes sense for me to take

Issue 83, pull 93

https://github.com/w3c/encrypted-media/issues/83

https://github.com/w3c/encrypted-media/pull/93

ISSUE-84

https://github.com/w3c/encrypted-media/issues/84

paulc: Mark created some use case text, Joe commented

… Mark changed the wiki to reflect Joe’s comments

markw: I think what I put in the wiki addresses the issue so we can close

paulc: was the intent of putting the material on the wiki is that that is where it would stay?

… or should impact the spec?

markw: there was a question of where it should go originally, and we decided the wiki is fine

joesteele: I have not had a chance to review, but assuming the changes are in line with my comments I am fine with closing

paulc: it would be good for folks to review if possible

ddorwin: I will review but this will be at the bottom of the queue

jdsmith: how do we link to the wiki?

paulc: I don’t think we do, but we can point to it if someone asked us the same question

… hopefully folks will be searching for this

To Be Implemented Issues

<paulc_> https://lists.w3.org/Archives/Public/public-html-media/2015Oct/0007.html

paulc: besides David and Jerry there are 8 issues that are not assigned

<paulc_> I would like to gather consensus on whether any of these issues need an explicit pull request and review or if they are all ready for direct implementation?

… Mark has suggested we use pull requests as a way of reviewing

… do any of these need a pull request for review?

<ddorwin> I was dropped

<ddorwin> dialing in

jdsmith: yes — some of them do not need a full pull request

paulc: ok — are there any specifically that you can point to?

markw: I would need to look through them to see which ones need a full pull request

paulc: action is on the editors to respond to the email or go through github and self-assign the issues

… would like some input on ETA to resolve the backlog

jdsmith: my plan is to have my list done by Friday, I might be able to review the others as well

<paulc_> Jerry: 8, 17, 36, 72, 73, 77

<paulc_> Not assigned: 10, 47, 60, 61, 62, 64, 71, 74

paulc: so you might be able to review these others as well? if you do please respond to the email to let the other editors take issues off the list

… first come first served

… Mark maybe you can grab some of these?

markw: I can do my assigned one this week and take on some more

paulc: this would help get the backlog down

… if they are hard maybe we do need a pull request

ddorwin: the ones left unassigned might have been unassigned for a reason — I need to double check

… we need to get these done by not necessarily by TPAC — we have decisions to make there

paulc: ok — just trying to make as much progress as possible

jdsmith: when we mark as to be implemented, we are asserting there is an agreed upon opinion.

https://github.com/w3c/encrypted-media/issues/31

s/https://github.com/w3c/encrypted-media/issues/30/https://github.com/w3c/encrypted-media/issues/14/

paulc: David removed the “needs feedback” from 19 and 14 yesterday — what are the next steps here?

<paulc_> ISSUE-19, ISSUE-14 and ISSUE-31 in the batch

ddorwin: have some old notes on the tedchnical details on how messages are dispatched

… this would let us resolve 19

<paulc_> https://github.com/w3c/encrypted-media/issues/14/

… there is general agreement on the others but need to make sure the foundations are correct

… these are the more important things I need to do

scribe: the order is 19, 14, and then 31 is blocked on 19

… 14 is also blocked on 19

<paulc_> David's response says: dispatching rules into a description of how that affects the intended behavior in issue #19. It doesn't make sense to implement #14 and #31 until we're using the correct primitives.

paulc: do you expect that we will be ready in two weeks to discuss?

ddorwin: maybe?

ACTION-93: Get in touch with webappsec wg about the "privileged context" which is more generic than saying https, etc."

<paulc_> https://lists.w3.org/Archives/Public/public-html-media/2015Oct/0011.html

paulc: this is pending

BobLund_: the objective here is to determine what we need to go back to WebAppSec with around trusted application context

… conclusion was no, but we need to get closure with some parties we are working with

paulc: will you be at TPAC?

BobLund_: no and the parties will not be there either

… they are certificate authorities

<paulc_> ACTION-93 is due in one month

BobLund_: thats fine

markw: this problem comes up in other contexts as well — the secure connection requirements — specifically in the 2nd screen working group

… we plan to raise this issue as TPAC

… think its something that groups should look at rather than waiting on a solution

paulc: so you are suggesting that Bob should outline the solution since there might be discussions at TPAC?

markw: yes

… a solution requires all devices to be given certificates by a CA but not clear that works as a general solution

BobLund_: that is the proposal, we are struggling with how that will work, specifically with private IP addresses

markw: think it is unlikely browsers will trust certificates bound to private IP addresses

<paulc_> ACTION-93: http://www.w3.org/html/wg/media/track/actions/93

<trackbot> Notes added to ACTION-93 Get in touch with webappsec wg about the "privileged context" which is more generic than saying https, etc." (really on bob lund).

… at least not to the same level of trust as to a bound DNS name

BobLund: I will outline and get that to you before TPAC — may try to participate on the phone as well

paulc: mark are you aware of the wiki for unconferences?

markw: yes - I will add to that

paulc: if you could add this information to that wiki that would be useful

<markw> https://www.w3.org/wiki/TPAC2015/SessionIdeas

markw: this is the collection of session ideas — no times or places yet

paulc: Bob thanks for attending and giving us an update

: https://github.com/w3c/encrypted-media/issues/70

: https://github.com/w3c/encrypted-media/issues/75

paulc: some of the issues mentioned earlier have been resolved

… 75 blocks 69 and depends on 68

… what will we do about this trio?

ddorwin: 75 we got a repsonse on — need to ping him back

… we can fix 68 independently — need a response from folks

paulc: can you ping the external expert on 75?

ddorwin: yes

paulc: can another member look at the original proposal and make some comments?

jdsmith: I can do that

paulc: if we get 75 and 68 we can figure out how to move on

EME status and bugs

paulc: building the agenda for the TPAC — lots of outstanding work items

… open to suggestions on what we should discuss and when

… since the charter has been extended we will be meeting under the auspices of our existing task force

joesteele: should we talk about issue 41 at TPAC?

paulc: I am not taking anything off the table for TPAC — Google can have a rep there

… can schedule it appropriately for them

… 9am start would be 7pm at night — telco might be difficult but we will try to have the right schedule as needed

… if we can make progress before that is strongly encouraged

ddorwin: I will at least provide the information about my concerns

wrap up

paulc: we will wrap up and meet again in two weeks

… agenda will be on the wiki, folks should add their comments
