This meeting

group: no other business

nigel: Notes no meeting on 25th December and 1st January

tmichel: We have agreement to publish the FPWD of WebVTT; I'm still waiting on the announcement.
... I publish the document in place, and then the web master adds the links, which is the publication process, as well
... as making the announcement and putting on W3C home page.

IMSC 1 review comments

nigel: Our plan for today is to go through all the comments and if we can move them all to Resolved then send replies.
... In order to do that we'll need to agree a response deadline for the commenter, which goes into the emails.

pal: I've had some comments from Andreas and Nigel, which I think are editorial only. I propose to edit them in place now.
... First one is a typo from nigel - double 'use'.
... For a future agenda, we should consider the general move to git instead of Mercurial, so when Glenn's present it
... would be good to discuss that.

Frans: +1 to using git

pal: Another from Nigel: for LC-2977. You're proposing to add conformance language and use the term "normal rendering"
... I'm concerned with using "normal rendering" which isn't defined.
... SHALL vs NOT SHALL - I don't think that's needed but could be okay.

nigel: The bigger point is that "no impact on presentation" could be misinterpreted as "no presentation" which isn't what we mean.

pal: This was a response to Andreas's point - I'd actually prefer to remove the sentence altogether.

andreas: From a practical point of view the text as written could be intepreted as requiring that forcedDisplay must be set to true for everything.

pal: That's only the case if displayForcedMode is true.

andreas: If you set the external parameter to true and none of the content has an applicable forcedDisplay attribute then
... nothing is shown.

pal: That's right - by default displayForcedOnlyMode is false.

andreas: The practical implication is that authors might always set forcedDisplay to true.

mike: It's important to note the relevant external context here, in which a track may be selected and displayed or not displayed.
... The forcedDisplayMode forces the deselected text content to play in specific circumstances.

nigel: We need to find an alternate form of words that addresses the editorial issue here.

pal: I'm happy to a) remove the last sentence or b) keep as it is but not c) use the term "normal rendering".

nigel: I'm not happy with leaving as is.

andreas: can we use something like "all other combinations ... do not change the computed presentation" or something like that?

pal: Glenn was adamant that this parameter should have no impact on other computed values - let's not introduce another problem.

nigel: How about removing the additional sentence and replacing "If the value of" in the previous sentence with "If, and only if, the value of" ...

andreas: Yes, that works.

pal: Okay, I've captured that.

https://www.w3.org/2006/02/lc-comments-tracker/34314/WD-ttml-imsc1-20140930/2977

pal: The resolution text does not need to be changed because it points to the latest editor's draft.
... Next is LC-2973

https://www.w3.org/2006/02/lc-comments-tracker/34314/WD-ttml-imsc1-20140930/2973

andreas: I like the solution in 6.2 but in 6.3 what we want to say here is that the namespace defined by W3C can only
... be added to by W3C and no other entities. The last sentence says that all undefined names in these namespaces are
... reserved for future standardisation by the W3C. I'm not sure if that's quite the right term.

pal: I copied exactly what was in TTML1.

andreas: Okay, if everyone understands the intended meaning then I'm fine with that.

pal: I tried to do exactly what TTML1 already does so at least it's the same.
... Next one is LC-2982

https://www.w3.org/2006/02/lc-comments-tracker/34314/WD-ttml-imsc1-20140930/2982

andreas: I think we've already worked on this (forced display). I was just thinking about the impact on authors for using
... the feature. I think it's correct as it says, and I have no further proposal for a change.

pal: The last one with a comment is LC-2978

https://www.w3.org/2006/02/lc-comments-tracker/34314/WD-ttml-imsc1-20140930/2978

pal: I think Andreas suggested that the section 2 Document Conventions should be a direct link to the section in TTML1
... rather than a general link?

andreas: Yes

pal: The challenge is I think the conventions aren't only in the TTML1 document conventions section. For example
... the XML representation is in TTML1 §2.3, but the way styling attributes are specified is in the styling section inline.
... So I wanted to cast a wider net rather than a narrower one.

nigel: I can't see anything defining a document convention in TTML 1 §8 Styling

pal: That's right - we're using the same convention as the styling attribute tables in TTML1 §8 but it isn't clearly
... defined anywhere even in TTML1. I don't think we can link to only one place.

andreas: The main reason for the comment was about the XML representation, where the bold attribute format is
... defined as 'required'.

pal: So we can add 'in particular see section 2.3 for the specification of the XML representation of elements'?

andreas: +1

pal: [edits in place with slight tweaks to the above wording for precision]
... I think that covers all the comments.

nigel: In that case I think we can set all the comments to one kind of Resolved or another.

pal: I don't know how to pick the different types of Resolved!

tmichel: They're resolved within the WG then we need the agreement from the commenter.

http://www.w3.org/AudioVideo/TT/Guide2LCtracker/overview.html#Resolution

nigel: I think we have to choose the appropriate Resolved-[yes|partial|no] status on a comment by comment basis.

jdsmith: That makes sense to me.

tmichel: The three options will show on the final disposition document with green/yellow/red colour coding

pal: When the comments are resolved, how do we notify the commenter?

nigel: If it's okay I will decide on the status for each one, and then we can send the replies.
... We need a feedback date though.

pal: I propose by next Thursday so we have the status by the next meeting.

tmichel: My notes do say 'if the comment meets the commenters request then we should put resolved-yes' etc.
... so before sending the response we have to set this status. Then there's another box for the commenter to agree.
... So there are two different levels.

nigel: I'll set the statuses.
... When I've done that I'll send thierry an email asking for the replies to be reviewed and sent.

tmichel: That's fine, then I'll track the responses from the commenters.

nigel: And we'll set a reply-by date of Thursday 20th November.

pal: I've checked in the modification to the tip, incorporating all the changes from today.
