Charter

https://www.w3.org/2002/09/wbs/33280/timed-text-2014/results

frans: describes EBU request for a change

TPAC 2014

http://www.w3.org/2014/11/TPAC/

nigel: any requests for f2f?

jdsmith: we should be fairly far along by October

nigel: Could be a good opportunity with a relative stable TTML2 and IMSC to work with the WebVTT folk on the mapping deliverable, whatever form that might take.
... I will propose that we have a f2f meeting - the question will be how many days do we need, and which days should we hold the meeting on?
... Monday, Tuesday, Thursday and Friday are the options.

jdsmith: travel is an important factor, otherwise it could be any one of those days.

nigel: bear in mind also CSSWG and HTMLWG meetings.

<scribe> ACTION: nigel to discuss with david singer possibilities for f2f before going ahead and adding TTWG to TPAC agenda. [recorded in http://www.w3.org/2014/03/20-tt-minutes.html#action01]

<trackbot> Created ACTION-274 - Discuss with david singer possibilities for f2f before going ahead and adding ttwg to tpac agenda. [on Nigel Megitt - due 2014-03-27].

Docs from other groups

nigel: iterates through docs from other groups as listed in the agenda.
... since the agenda there's also been a reversion to LC for CSS Flexible Box Layout Module Level 1
... We plan to use this!
... URL is http://www.w3.org/TR/css3-flexbox/ and Editor's Draft is http://dev.w3.org/csswg/css-flexbox-1/
... I encourage all to review this and I will collate any comments. They suggest a 4 week review period ending April 22.
... therefore comments back to me (I'll add an agenda item for this) by 17th April at very latest.

pal: Suggests process to put together comments and submit our comments to reflector.
... would be good to have a feedback comments document from the group for TTWG review prior to submission to CSS WG by the chair.

nigel: agrees

pal: one comment is based on change proposal 15 - it would be helpful to get consensus on CP15 before submitting comments based on it.
... of course individuals can always comment anyway.

Change Proposals

nigel: CP15 is the only one with any movement I'm aware of so I'll walk through the changes

https://www.w3.org/wiki/TTML/changeProposal015

nigel: Peter Linss of the CSS WG responded that " the box-decoration-break property was moved to the CSS Fragmentation spec"
... and "we expect that spec to reach CR before the end of the year. Hopefully this satisfies your needs."

http://drafts.csswg.org/css-break/#break-decoration

nigel: the timescales are quite close to those for TTML2 so we may consider making a response to this.

jdsmith: what's the purpose of the Fragmentation spec

https://www.w3.org/wiki/TTML/changeProposal015#box-decoration-break

nigel: we intend to use css box-decoration-break: clone property to achieve the desired effect. This is in the CSS Fragmentation spec now.
... walks through the Issue-286 proposal in CP15, opens up for comments, noting that Glenn is particularly interested.

pal: TTML1 processors that see that attribute - is the expectation that they ignore it and not add padding?

nigel: yes because they'd use the profile and feature mechanism for processors to work out if they need to support it
... so processors would ignore it if they don't know it.

pal: that would be a nice way around it

nigel: if it is ignored then impact is slightly less readable text but no unpleasant text wrapping impacts.

pal: it would be good to verify that existing implementations quietly ignore attributes (without complaining) in the tts namespace that they do not recognise.

nigel: happy for implementors to verify this or we could alternatively put this and other new TTML2 features into a new namespace

pal: yes that's another possibility.
... having an ignorable attribute provides a nice way forward for any new attribute in the TTML2 namespace

nigel: yes, I'd be interested in glenn's views on this and the interaction between this and profile features
... that's all on CP15 for this week - I'm looking at the use of flex for multiple row alignment too, which is work in progress.

<scribe> ACTION: pal review issues in CP12 and if one is needed for handling new attributes in TTML2 in same namespace as TTML1 then raise it, and link to issue-286. [recorded in http://www.w3.org/2014/03/20-tt-minutes.html#action02]

<trackbot> Created ACTION-275 - Review issues in cp12 and if one is needed for handling new attributes in ttml2 in same namespace as ttml1 then raise it, and link to issue-286. [on Pierre-Anthony Lemieux - due 2014-03-27].

AOB

nigel: we seem to have an option on the tracker to send emails on changes to issues and actions by default - the current default is not to send emails.
... I propose changing this default to 'do send emails unless member has opted out'
... this may give a more positive experience than people have now.

<tmichel> no objection.

Action nigel Request tracker default change to 'email'

<trackbot> Created ACTION-276 - Request tracker default change to 'email' [on Nigel Megitt - due 2014-03-27].

nigel: There's going to be some service outage at MIT next week - not sure of the impact to W3C..

tmichel: should be a short outage.

nigel: Outages likely on Sat 29th March to servers
