frans: describes EBU request for a change
TPAC 2014
[11]http://www.w3.org/2014/11/TPAC/
[11] 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
[12]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 [13]http://www.w3.org/TR/css3-flexbox/ and Editor's
Draft is [14]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.
[13] http://www.w3.org/TR/css3-flexbox/
[14] http://dev.w3.org/csswg/css-flexbox-1/
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
[15]https://www.w3.org/wiki/TTML/changeProposal015
[15] 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."
[16]http://drafts.csswg.org/css-break/#break-decoration
[16] 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
[17]https://www.w3.org/wiki/TTML/changeProposal015#box-decorati
on-break
[17] 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
[18]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
rrsagent. publish minutes
