<trackbot> action-176 -- Roderick Sheeter to Test hmtx transformation over google fonts corpus (how many lsb == x-min for all glyfs, what savings) -- due 2015-05-27 -- OPEN

<trackbot> http://www.w3.org/Fonts/WG/track/actions/176

Vlad: we had comments on the daalton Maag dataset

d/daa/Daa

Vlad: good to get on the google font corpus too
... RSheeter ?

<RSheeter> apparently I'm on mute somehow

<RSheeter> I can hear you. I'll try the hmtx thing over Google Fonts corpus. I thought we were just going to accept Cosimo's results.

Vlad: assuming those results are in line with the ones from Cosima, any objectiosn to modify the spec to add extensibility and then use that for htmx and vtmx transforms

kuettel: would this be optional and thus backwards compatible?

Vlad: yes for conformant generators; no for comformant readers

kuettel: okay

ChrisL: sounds god to me

Khaled: may be an issue for multiple formats for different browsers. serving two flavours of woff 2

Vlad: its an interim solution when browsers have 2.0 but not 2.1, so rejects font
... this should be of short duration. it gives us extensibility down the line

kuettel: worth noting we could not have done it in the past, but the regular update model for browsers makes this feasible

Vlad: do not expect frequent updates for WOFF2
... this minimizes disruption
... proposes adopting proposal from jfkthame

(general agreement)

Vlad: needs additional spec text for the transform

<scribe> ACTION: vlad to add the htmx transform to spec [recorded in http://www.w3.org/2015/06/03-webfonts-minutes.html#action01]

<trackbot> Created ACTION-178 - Add the htmx transform to spec [on Vladimir Levantovsky - due 2015-06-10].

conformance requirements

need to weed out the untestables - authoring tools do then, browsers don't care

http://lists.w3.org/Archives/Public/public-webfonts-wg/2015Jun/0001.html

use OUGHT TO from RFC 6919

https://tools.ietf.org/html/rfc6919

The phrase "OUGHT TO" conveys an optimistic assertion of an

implementation behavior that is clearly morally right, and thus does

not require substantiation.

although "WOULD PROBALY" also works

The phrase "WOULD PROBABLY" indicates the authors expectation about

what a reasonable implementation is likely to do in a given case.

There is no requirement for implementations to be reasonable.

<RSheeter> can we work in MAY WISH TO?

Vlad: requirement to always produce the shortest encoding is in the same category. we ave a test on UA for this
... will flag if there is an issue with an authoring tool
... suggest changing to remove the conformance requirement

ChrisL: agree

action vlad to update conformance statements as per https://lists.w3.org/Archives/Public/public-webfonts-wg/2015Jun/0001.html

<trackbot> Created ACTION-179 - Update conformance statements as per https://lists.w3.org/archives/public/public-webfonts-wg/2015jun/0001.html [on Vladimir Levantovsky - due 2015-06-10].

Vlad: hope we don't have more untestables. RSheeter please introduce your mail from just before meting

<RSheeter> http://dev.w3.org/webfonts/WOFF2/spec/#FileStructure

RSheeter: no-overlap, in terms of writing tests, a larger set of much more focussed requirements
... on a per-table basis

<RSheeter> contrast with http://www.w3.org/TR/WOFF/#Metadata, which is very specific in its assertions

Vlad: WOFF2 limits the places where extra data can be inserted. betwwen data blocks only, very different compared to WOFF 1.0

ChrisL: slight concern about ending up with a near-exhaustive list

RSheeter: no need to remove current requiremnt, but add some specific ones

Vlad: discuss at f2f

Final F2F planning

Vlad: will set up a conference, no practical limit on participant numbers
... preliminary agenda will go out on Friday
... meeting on Tuesday and Wednesday

(adjourned)
