1. Continue discussion on is 0 tolerance for accessibility conformance practical?
See github issue #1767.
Avneesh Singh: we had a long discussion about this issue during last call
… Charles suggested to use a string “significantly” conforms to
… but then we had some comments on the issue
John Foliot: I like the idea to use “significantly conforms to”
… I the VPAT you can describe it, to tell that perfect is a goal
… but achieve it is complicated
… in the USA an accessibility problem can goes to a legal issue
Matt Garrish: I think it’s ok for a publisher to tell it in the accessibility summary
… I have concerns about writing in specs what it means to be significantly accessible
Avneesh Singh: do you mean that you can put whatever you want in the conformsTo
field?
Matt Garrish: yes
John Foliot: I’m active in the Silver WG, we are working on the score system
… in conformsTo
may we link so a self-published accessibility statement (for publishers)?
Matt Garrish: we have certifierReport
metadata for doing this
… it’s optional
John Foliot: the conformsTo
metadata instead is not optional, it is mandatory
… what about about making only one in conformsTo
and certifierReport
mandatory?
Matt Garrish: actually conformsTo
is not mandatory
Bill Kasdorf: to end users what is most interesting is what it doesn’t conform
… it would be useful to express it
Gregorio Pellegrino: for local legislation the conformance is important
… also in metadata we don’t have ways for telling which accessibility issues are present in a document
George Kerscher: I don’t think we should get out from Silver
John Foliot: +1 to George
John Foliot: WCAG 3 is “far off” IMHO
Avneesh Singh: is it a problem to have conformsTo
linking to WCAG and then in the accessibilitySummary
telling that there may be issues?
George Kerscher: I think we should not worry about legal issues
John Foliot: my background tells me that think about legal risks is important
… I think that standards should not enable contractions
… I think we should balance it
George Kerscher: what does the the UX metadata guidelines tell to display when conformsTo
is empty?
Avneesh Singh: nothing or unknown?
George Kerscher: so you can use certifierReport
instead conformsTo
John Foliot: some certifier require to have conformsTo metadata for their certification
… so it is not “optional” for being certified
… I think we need a formal reference to link to
Matt Garrish: we can add in the specs that if partial conformance is present, then the certifierReport
is mandatory
… in the conformanceTo we may use EPUB11-WCAG21-A-PARTIAL
John Foliot: +1 Matt - that’s what I personally would like to see: addressing a real-world issue with a “standardized” solution
Bill Kasdorf: +1 to Matt
John Foliot: I would also suggest to define a “standard” way to make certifier reports
… VPAT may be a solution
Matt Garrish: sure, we can recommend it
Gregorio Pellegrino: for me the certifierReport
should be per publication and not for all publications
Matt Garrish: I don’t know
Bill Kasdorf: I’m favor for this approaches, but I see many VPATs that are false
… a lot of publishers are not able to read VPATs
John Foliot: to be clear, I am not advocating using a VPAT per-se, but rather look at VPATs as a model for conformance reporting
Bill Kasdorf: I think that have a report per publication is useful plus a report from the publisher telling on what they’re working
Wendy Reid: I’m concerned about telling that you must have to create a report for titles
… I think trade publishers would not use it, because it is not meaningful for retailers
Avneesh Singh: why not relaxing the report, if we have accessibilitySummary
… ?
Matt Garrish: yes, I think there are different ways to achieve it
Avneesh Singh: I think we had an excellent discussion, Matt can you now propose changes for the specs?
John Foliot: I think there are differences between prose versus machine-readable metadata
… so we should make the distinction clear in the specs
… for example telling the conformsTo MUST be an URL
Matt Garrish: we had this discussion for EPUB Accessibility 1.1
… we had issues for complex URLs
… I think that we can find a way using conformsTo
plus certifierReport
2. TPAC meetings to schedule with APA and other accessibility groups. Two meetings are scheduled for now.
Avneesh Singh: we have only two meetings right now, one for public registry
… it’s not EPUB 3 specific, more on publishing community
… the other meeting is about the sound hazard propriety
… I wrote an email, they’ll discuss it in the Silver meeting
… we should be present
… I think that defining an agenda is important
… for sure we may discuss the horizontal review
… Wendy do you think are we ready in September to trigger the review?
Wendy Reid: I think so
… this week we’ll discuss accessibility issues
Avneesh Singh: great, any other items for the agenda?
Wendy Reid: I know APA wants to know more on accessibility in EPUB
Matt Garrish: I think we should ask them what the “publication profile” they’re working on means
… I don’t know the state-of-the-art, but I think it worth discussing it
John Foliot: from my point of view: WCAG 3 is looping in defining the the scoring and conformance model
… I proposed to define profiles
… my proposal was to define profiles based on WCAG tests
… as there is a subset of WCAG for PDFs
… I also proposed to public declare protocols you are using in creating content
… it’s WCAG will used by different contents, I think that defining profiles is strategic
Matt Garrish: yes, I think that something can be developed inside WCAG and something in profiles
Bill Kasdorf: Most people would consider Finnegans Wake not accessible.
Avneesh Singh: In conclusion I think we need a meeting with APA and WCAG 3.0
… do we want it together or separate?
John Foliot: I suggest separate
3. Reminder to review of EPUB Accessibility specs and techniques.
Avneesh Singh: Wendy, I can ask APA for reviewing EPUB 3.3
Wendy Reid: fine
Avneesh Singh: please file issues about EPUB Accessibility (if you have)
… we are going to finalize the document
