Review the first public working draft
Vlad: Thanks jdaggett for reviewing the spec

jdaggett: most of these are editorial
... two major things
... section 8 conformance, checksum must be correct, implication is
that checksum is computed and checked,
... must either correct the values or issue a warning
... need to be consistent, reject or warn?
... many checks need to happen but that is not part of woff, hapens
once a font is converted
sergeym: validating a checksum is an additional step
jdaggett: not clear if we can reuse the header checksum or required
to recompute it
sergeym: UA does not change table structure
... so the checksum is still valid
jdaggett: wording says the tool should validate it
Vlad: sergeym seems to be agreeing that checksum validation should
not be required of UA
resolved: UAS need not validate checksums
<scribe> ACTION: jjonathan to clarify that checksums are not checked
by a user agent [recorded in
[13]http://www.w3.org/2010/08/04-webfonts-minutes.html#action01]
<trackbot> Sorry, couldn't find user - jjonathan

<scribe> ACTION: jonathan to clarify that checksums are not checked
by a user agent [recorded in
[16]http://www.w3.org/2010/08/04-webfonts-minutes.html#action04]
<trackbot> Created ACTION-12 - Clarify that checksums are not
checked by a user agent [on Jonathan Kew - due 2010-08-11].
jdaggett: better to move the conformance requirenents into section
8, list for tools and user agents
Vlad: yes appendices should be informative so notrmative text should
be moved out of there
... of if it looks normative bit isnt it should be reworded
jdaggett: structural issue, repeating similar ideas in 2 parts of a
document they get out of sync over time
... woff processor, not defined
ChrisL: agree, if it means UA
jdaggett: no need to define for other than a user agent?
ChrisL: not authoring tools?
Vlad: encoder and decoder need to understad the same format
jdaggett: should not say UA one place and woff processor other
places
Vlad: in general agree, but slightly broader scope. Used by tool
creators for creation and consumption
<John> Could we have a general term such as 'WOFF client'
ChrisL: as an example a woff validator could say if the checksums
are wrong, even though a ua is not required to check them
sylvaing: need to clearly distinguish encoders and decoders.
processor could apply to both
jdaggett: agree that sizes should be specified in bytes for example.
trivial to add
ChrisL: should say that WOFF stands for web open fornt format
Vlad: another comment from Eric Muller partly addressed by
jdaggett's edits
ChrisL: all of Bobs concerns seemed to be addressed by John
Vlad: there was a concern about padding that follows the last table
so is not between tables
<Vlad>

jdaggett: current spec does not completely address it
... under overal lfile structure in section 2, (quotes) no
extraneous data outside tha table. its too vague.
... proposed wording, bob replied it would allow data after the last
table
... make change to disallow extraneous data outside the font
... should UAs load a font that has gaps that are more than padding
Vlad: think the spec already says this
jdaggett: should be in conformance requirements
... change 'between font tables' to include before and after tables
too
<scribe> ACTION: jonothan t change conformance rwquirements to
disallow extraneous data anywhere and require ua to reject a font
contasining it [recorded in
[18]http://www.w3.org/2010/08/04-webfonts-minutes.html#action05]

<trackbot> Created ACTION-13 - T change conformance rwquirements to
disallow extraneous data anywhere and require ua to reject a font
contasining it [on Jonathan Kew - due 2010-08-11].
Vlad: Eric Muller comments I responded to
ChrisL: surprised by Eric's comments
jdaggett: he seemed to say that everything should be in OT tables
(or an extension)
cslye: he said that metadata that is not woff specific should be
inside the fotnt; talked with him about that
... in private discussion
Vlad: wanted to respond to his comments right away
Typecon 2010:
Vlad: its in 2 weeks
... john suggested woff presentations better done by tal and erik
... program lists john as the speaker there
erik: agreed
Vlad: please draft something for the group to discuss
erik: will post over the next week
Vlad: important to get the message across, what woff does and what
it is for
... also ChrisL can you do the wg part?
ChrisL: yes sure
... need to tell Tamye about that and check its ok?
cslye: no its ok, the panel discussion is more tightly managed. wg
slot is fairly open
ChrisL: so who is on the panel?
cslye: panel is brian mason, cslyye (reads from program)
<cslye> TypeCon webfonts panel discussion: Participants include
Bryan Mason, moderator (Typekit), Christopher Slye (Adobe), Bill
Davis (Ascender), Tom Phinney (Extensis), Adam Twardoch (FontLab),
Raph Levien (Google), Erik van Blokland (LettError), Simon Daniels
(Microsoft), Vladimir Levantovsky (Monotype Imaging), John Hudson

sylvaing: session is on friday? and wg meeting tues?
John: yes and css3 on weds
.woff party friday night
Planning of the F2F meeting.
Vlad: be ready to discuss conformance requirements and testable
assertions
... will get more details on location. 10-6pm is the time. will get
room details
WOFF publicity/promotion at Typecon
(discussion about publicity)
review spec for conformance and testable assertions
ChrisL: related my experience on defining 'lossless; wrt PNG spec,
might apply to WOFF too
Vlad: fringe cases may need some adjustments
aob
erik: doing experiments with xslt to render the metadata
Vlad: may be useful as informative appendix. jkew said not in spec
but can be handy to make available
ChrisL: its more illustrative
... erik please post a link
erik: sure
vlad: anything else?
