action-195
<trackbot> action-195 -- Pierre-Anthony Lemieux to Proposing

<trackbot>
[17]http://www.w3.org/AudioVideo/TT/tracker/actions/195
[17] http://www.w3.org/AudioVideo/TT/tracker/actions/195
nigel: do we need an absolute value reference rather than the
term 'highest'?
pal: yes we can improve that sentence
glenn: i.e. round up not down?
pal: yes
glenn: this raises the issue of tracker not generating
notifications on changes to actions or issues.
thierry: unfortunately there is no such feature. For new
actions an email is sent, but not when the status changes. Will
check re new comments.
glenn: also requested this feature on the AC list recently. In
the meantime we'll have to manually review actions and issues.
thierry: I understand the issue. I hope sysreq knows about
this. I will check this is on the tracker page list.
<glenn> action thierry to check if feature request for tracker
notifications on action/issue new comment or status change has
been added to requested feature list
<trackbot> Created ACTION-198 - Check if feature request for
tracker notifications on action/issue new comment or status
change has been added to requested feature list [on Thierry
Michel - due 2013-09-12].
glenn: phillipe, we're close to packaging TTML1 with editorial
changes since the PER so you can start the publishing process.
... guidance on that, e.g. a target date, would be useful.
plh: need to close the loop with IANA and then get director's
approval for publishing the recommendation. Any changes since
the end of the last review?
glenn: yes, a variety of editorial changes, documented here:
<glenn>
[18]https://dvcs.w3.org/hg/ttml/raw-file/default/ttml1/spec/ttm
l1-changes.html
[18] https://dvcs.w3.org/hg/ttml/raw-file/default/ttml1/spec/ttml1-changes.html
glenn: this lists changes since the PER was published, which
all basically resolve comments made on PER or in working group
review.
action-196
<trackbot> action-196 -- Pierre-Anthony Lemieux to Check
proposed resolution to issue-159 in relationship to issue-231
and issue-229 -- due 2013-09-05 -- OPEN
<trackbot>
[19]http://www.w3.org/AudioVideo/TT/tracker/actions/196
[19] http://www.w3.org/AudioVideo/TT/tracker/actions/196
issue-231
<trackbot> issue-231 -- Individual character rotation -- open
<trackbot>
[20]http://www.w3.org/AudioVideo/TT/tracker/issues/231
[20] http://www.w3.org/AudioVideo/TT/tracker/issues/231
pal: it looks like the proposed resolution to issue-159 solves
issue-231 as well
glenn: was the request intended to support arbitrary angles or
just 90 degrees either way?
pal: 90 degrees only.
glenn: the values in issue-159 were mixed sideways and upright
where sideways could be clockwise or anti-clockwise depending
on the block progression in vertical mode
... and the writing mode. There are use cases for both
directions, but they are effectively controlled by the writing
mode.
... CSS3 defines two additional modes: sideways-left and
sideways-right which allow the direction to be set
independently of the writing mode.
pal: I think this matches the SMPTE requirement, i.e.
individual rotation of each character left or right by 90
degrees.
glenn: the other issue is rotation around the centre of the
glyph. In general rotation is around the origin of the glyph
rather than the centre.
... this depends also on whether the baseline is horizontal or
vertical.
pal: 'around its centre' really means that each glyph should be
rotated individually so we need not worry about that.
issue-159
<trackbot> issue-159 -- Text orientation in I18n script
processing -- pending review
<trackbot>
[21]http://www.w3.org/AudioVideo/TT/tracker/issues/159
[21] http://www.w3.org/AudioVideo/TT/tracker/issues/159
<glenn> issue-159: glenn to add sidewaysLeft and sidewaysRight
values
<trackbot> Notes added to issue-159 Text orientation in I18n
script processing.
<glenn> issue-159: see also issue-231
<trackbot> Notes added to issue-159 Text orientation in I18n
script processing.
pal: need to wait for Sean to confirm if this resolves
issue-159
... issue-229 seems different from issue-231 and issue-159. It
is instead of glyph rotation concerned with changing the
progression direction.
<glenn> issue-229: glenn thinks this isn't related to
issue-159, so sean needs to elaborate if he thinks otherwise
<trackbot> Notes added to issue-229 Mixed vertical-horizontal
progression direction.
pal: so the resolution to issue-159 will not resolve issue-229
close action-196
<trackbot> Closed action-196.
<mike> I need to drop for this week. Hear everyone next week.

issue-176
<trackbot> issue-176 -- Adding support for extent and origin
attributes on block elements -- pending review
<trackbot>
[25]http://www.w3.org/AudioVideo/TT/tracker/issues/176
[25] http://www.w3.org/AudioVideo/TT/tracker/issues/176
glenn: the problem with putting origin and extent directly on p
or div could be misinterpreted as meaning the size of the
allocation rectangle or the content rectangle to apply
... this is the case if for example in CSS you specify a width
for a block element then it is interpreted as a declaration of
how much allocation area to assign to the block and not
... a declaration of an absolutely positioned region in which
to put the block.
... my proposal, subject to Sean's review, is to add an inline
region, like an inline animation element, as a child of a block
element.
... This is a shorthand for defining the region in the header
and referring to it via IDs.
... this is one for the agenda in the f2f meeting. Want to keep
as pending review for the time being.
... in the TTML2 editorial draft, under the terminology section
2.2 I have added new definitions for inline region and out of
line region, also incidentally inline and out of line
animation,
... I also modified the syntax for the div and p elements in
7.1.4 and 7.1.5 to add to its content models an optional layout
class immediately after the animation class.
... Under the section 9.3 on layout semantics I have pencilled
in a new subsection called Inline Regions 9.3.2 which needs to
be filled in.
... Minor changes are likely in 9.3.3 as a consequence.
... This technique will minimise the changes to the semantics
of the parent synchronic document construction and layout
processing.
... The original idea came from a desire to serialise content
in a way that doesn't require pre-defining all of the regions
up-front and instead allow them to be defined coincident with
the block element
<glenn> issue-176: nigel asks about whether region needs full
specification or can be inherited
<trackbot> Notes added to issue-176 Adding support for extent
and origin attributes on block elements.
glenn: we could specify on the root or layout element the
styles etc to inherit in inline or out of line regions
<glenn> ACTION: glenn to create new issue about need for region
elements to obtain inherited styles, possibly from layout or tt
element [recorded in
[26]http://www.w3.org/2013/09/05-tt-minutes.html#action01]
<trackbot> Created ACTION-199 - Create new issue about need for
region elements to obtain inherited styles, possibly from
layout or tt element [on Glenn Adams - due 2013-09-12].
issue-178
<trackbot> issue-178 -- initial values and style set
calculations are unclear, especially for transformable
attributes -- pending review

Border, etc. related to character edge attributes -- pending
review

[29] http://www.w3.org/AudioVideo/TT/tracker/issues/193
issue-203
<trackbot> issue-203 -- Add ttp:version to allow author to
indicate which version of TTML content was created for. --
pending review
<trackbot>
[30]http://www.w3.org/AudioVideo/TT/tracker/issues/203
[30] http://www.w3.org/AudioVideo/TT/tracker/issues/203
glenn: this now implemented in TTML2 draft
pal: is the namespace going to change for TTML2?
glenn: there's no plan to change it. The namespace is defined
as being extensible under control of the TTWG.
pal: so this would be a way to tell if a TTML document conforms
to TTML1 or TTML2?
glenn: reads draft text.
... this is intended to be separate from profile conformance
and definition. It should have no mandatory normative role in
processing.
nigel: might this be used for behaviour changes in processors
that don't have defined profiles?
glenn: there are two questions there: firstly profile
mechanisms and secondly the definition of new profile features
to cover changes in behaviour
... For the time being we can't concretely answer this - we may
in the end take it out as being unnecessary or add more
semantics that trigger off its value. For future discussion.
... It would be useful to add this to the discussion list for
the TPAC meeting.
<glenn> ACTION: glenn to add ttp:version to items for possible
F2F agenda [recorded in
[31]http://www.w3.org/2013/09/05-tt-minutes.html#action02]
<trackbot> Created ACTION-200 - Add ttp:version to items for
possible f2f agenda [on Glenn Adams - due 2013-09-12].
pal: we have three mechanisms now: namespace, content profile
and version. It would be good to understand the interplay
between those three.
glenn: we can not redefine existing profile labels; we can only
add new profiles. Similarly with features.
pal: will the TTML2 profiles unambiguously define the version
used?
glenn: no - I could create a TTML2 version document that
requires dfxp-full or dfxp-presentation so they're orthogonal
concepts
pal: so ttp:version is completely informative because the
processor only needs to know which normative provisions were
used.
... unless we're really clear people will come up with crazy
ways to process/reject documents using faulty logic
glenn: we don't know yet if we will not define normative
semantics around the use of a version defined this way. For
example we may change basic conformance processing changes
... we are also making changes about concrete syntax - in
version 1 there were recommendations that will be normative in
v2. Similarly with time expressions.
... I can't predict where we'll end up. In SVG it seems to be
useful. Similarly in XML headers, and by analogy it could be
useful here.
nigel: there's one use case here that's clear - processors will
need to know the TTML version to understand the profile
mechanism if we change that.
pal: we can already use the profile mechanism.
glenn: we're thinking about declaring content profile
independently of what's required by a processor. You could
create a TTML2 document that declares conformance with a TTML1
profile and use
... a TTML1 profile for declaring what support a processor
requires.
pal: That's still unambiguous without needing version.
glenn: I don't expect to mandate that a TTML2 document declares
its conformance with a particular profile
... If it's pure metadata we can consider removing it. I
suggest you submit an issue for this - could be to change it to
ttm:version instead of ttp:version.
... I suggest we need to think more about this.
pal: I will file an issue.
... we need to specify very clearly how we communicate
semantics and version conformance.
close issue-203
<trackbot> Closed issue-203.
issue-204
<trackbot> issue-204 -- TTML.next should probably be 2.0, not
1.1 -- pending review
<trackbot>
[32]http://www.w3.org/AudioVideo/TT/tracker/issues/204
[32] http://www.w3.org/AudioVideo/TT/tracker/issues/204
close issue-204
<trackbot> Closed issue-204.
issue-208
<trackbot> issue-208 -- Define behavior for unsupported colors.
-- pending review

[33] http://www.w3.org/AudioVideo/TT/tracker/issues/208
<tmichel> I am sorry I must leave to an appointement ...
<tmichel> Bye.
nigel: unsure how this is resolved by the closest color
calculation
... it doesn't maintain contrast where indicated, so foreground
and background colors could end up the same where contrast is
required.
close issue-208
<trackbot> Closed issue-208.
issue-225
<trackbot> issue-225 -- tts:fontSize as percentage of container
dimensions -- pending review

tml#style-value-length
[35] https://dvcs.w3.org/hg/ttml/raw-file/tip/ttml2/spec/ttml2.html#style-value-length
pal: likes the idea of an explicit viewport size relationship
mechanism
... there are now two ways to do this. Either use cell
resolution or this one which is really explicit.
glenn: that's correct. If it happens that an em square matches
a cell size then there's a third way.
nigel: when calculating vmin or vmax should non-square aspect
ratios be taken into account?
glenn: the width and height of the root container region turns
into a specific value in TTML pixels, not related to aspect
ratio. The pixel aspect ratio parameter comes into play
independently.
action nigel to check if pixel aspect ratio makes a difference
when performing the min and max comparison
<trackbot> Created ACTION-201 - Check if pixel aspect ratio
makes a difference when performing the min and max comparison
[on Nigel Megitt - due 2013-09-12].
pal: what should the preferred way of achieving this be, for
document authors?
<glenn> issue-225: add comment under tts:fontSize indicating
that vw/vh could also be expressed using cell (c) units
<trackbot> Notes added to issue-225 tts:fontSize as percentage
of container dimensions.
<glenn> action-201: is associated with issue-225
<trackbot> Notes added to action-201 Check if pixel aspect
ratio makes a difference when performing the min and max
comparison.
issue-227
<trackbot> issue-227 -- <p> fade-up and –down -- pending review
<trackbot>
[36]http://www.w3.org/AudioVideo/TT/tracker/issues/227
[36] http://www.w3.org/AudioVideo/TT/tracker/issues/227
glenn: describes new animation feature that addresses both fade
up and fade down and other use cases.
pal: this appears to resolve the opacity requirement. There's
another issue open relating more closely to animation
requirements.
glenn: animation is needed for the opacity requirement and
could not be with set.
close issue-227
<trackbot> Closed issue-227.
glenn: won't be able to attend next week
nigel: won't be able to attend next week or the week after.
pal: won't be able to attend the 19th.
<glenn> regrets for nigel and glenn for Sep 12
<glenn> regrets for nigel and pal for Sep 19
