I've started the agree upon wording for the Accessibility Metadata Success Criteria in Issue #82


https://github.com/w3c/wcag21/issues/82



It would be a AAA requirement with SC language such as this.


=Accessibility Metadata=
Accessibility Metadata is provided which describes the accessibility characteristics of the content using an openly published vocabulary. At a minimum this is a machine readable description either on the page or referenced from the set of pages to which it applies. A human readable summary may also be provided.

Hi Tzviya,


To me, the first priority for having a success criterion about metadata is to ensure it fits with the conformance claim section in WCAG 2.0 right now. If the through metadata you can't express what WCAG itself recommends doing with a conformance claim, then that seems too limited to me.


For reference: https://www.w3.org/TR/WCAG20/#conformance-claims


Further more, we can't talk about conformance of sites. WCAG conformance can only be claimed at a page level. At most a claim can be made that all pages on a website are conforming. Practically, for any website larger then a few pages such a claim is hard to make.


A second part to consider is how the WCAG Evaluation Methodology fits into this. It does actually have tools to report on the accessibility of websites as a whole (these are not conformance claims though). You can find WCAG-EM Here: https://www.w3.org/TR/WCAG-EM/


Lastly, regarding Accessibility Conformance Testing Taskforce (ACT). It is currently hard to speculate exactly what the outcome of this will look like, but there are a few things we can reasonably assume today. A critical component to why ACT is happening is that we want to be explicit about how accessibility results are gathered. For the same reason you mention indicating who certified something. Not all WCAG claims are equal. ACT means to make the test procedures used for WCAG testing explicit.




I hope this sets a few things up for the discussion soon. I think there is a whole lot of things to work through if we want to be able to get a success criterion in, but I'm very excited to see if we can make this work!

Wilco

   Hi David,
  
 The properties that we have been working on are available in two places. There are some terms were written a few years ago (and derive from the IMS Global Access for All Project). These are linked to from  https://schema.org/accessibilityFeature. The wiki details information at  https://www.w3.org/wiki/WebSchemas/Accessibility. 
  
 The newer, pending terms are available at:
 http://pending.schema.org/. 
 http://pending.schema.org/accessMode
 http://pending.schema.org/accessModeSufficient
 http://pending.schema.org/accessibilitySummary
  
 If I’m understanding your proposal correctly, you would like to see a new property called AccessibilityConformance, with predefined values that align with WCAG levels. That sounds like a great idea, but we would have to go through the schema.org extensions process [1]. That is how we reached all of the other properties. We have also talked about including information about conformance and/or certification. We thought it would be helpful to include not just what the site conforms to but who certifies that the site is conformant. There are lots of sites that claim to be WCAG AA-compliant, but that is a very broad statement. 
  
 So, if there is language on the wiki that you would like to edit so that we reflect more about WCAG, we can do that. We cannot add a property at this stage. We are happy to work on adding more accessibility properties in the future. The schema.org CG seemed really interested in growing this, not just from a WCAG perspective but also expanding scope to include information such as whether physical locations include wheelchair ramps.
  
 Thanks,
 Tzviya

   Hi Tzviya
 
   
 
  The WIKI seems to be documenting the Schema.org accessibility properties, which is helpful but I'm not sure what I could recommend for that page given that it just documents what's in the standard, through an accessibility lens. Maybe I'm missing something.
 
   
 
  My proposal is to introduce a simply way to report conformance through meta data, and the properties I proposed where because I didn't see anything on Screma.org that did that.

   Hi David,
  
 Thanks for the input. 
  
 Proposing new Properties and their values to schema.org is not quite the same as making editorial changes to the wiki. It took months of work for the existing properties to be approved by the schema.org CG. These proposals look great, but they would need to be proposed to the committee. 
  
 The changes that we can make at this point are to the language in https://www.w3.org/wiki/WebSchemas/Accessibility. There is no explicit mention of WCAG anywhere on this site. Would you recommend mentioning WCAG on this site? Can you provide specific language?

 Subject: Meta Data
  
   On the call today it was decided to move forward with a new AAA for MetaData from DPUB perhaps something simple like
 
   
 
  SC XXXX Metatdata: Metadata is provided which describes the accessibility characteristics of the content
 
   
 
  The understanding could reference Schema.org
 
    
 
  It was also requested by dPUB for us to propose any new Meta Data terms for Scema.org we'd like to see. I suggest the following:
 
   
 
  (1) The WCAG level of conformance claimed
 
  (2) The technology relied upon for conformance
 
   
 
  For the first property I could see something like this:
 
   
 
  accessibilityConformance: 
 
   
 
  with the following values for each of the WCAG 2 and 2.1 Levels and more could be added if further standards show up.
 
   
 
  levelWCAG2-A
 
  levelWCAG2-AA
 
  levelWCAG2-AAA
 
  levelWCAG2v1-A
 
  levelWCAG2v1-AA
 
  levelWCAG2v1-AAA
 
 
   
 
   
 
   ​I'm not sure how to do the 2nd. Technology relied upon​, because i'd hate to limit the values.  Maybe just start with the conformance level.

    Hi David
  
 I recall that a “set of software programs” was something that few of us have experienced although one member of the Task Force assured us that he had spotted one “in the wild”. I couldn’t recall whether we agreed that a set of documents was similarly rare (although I think that, with the very tight conditions, it probably is).
  
 I do recall that one of the arguments for not including these success criteria for documents was the concern that a large amount of time could be spent by people evaluating to the standard to search through what could be large ICT systems trying to identify if there were any sets of software – only to get a negative answer in almost all cases. I also recall that a problem could be that something that did meet the set of documents at one point might no longer be a set of documents if updates to part of the set were made.
  
 Overall, the conclusion were that:
  
 -          including the interpretation of these success criteria in the form that they were written was unlikely to lead to an improvement in accessibility for the vast majority of ICT procurements (in the same way that they are for Web pages); 
 -          much time could be wasted in all ICT procurements trying to identify if any of these rare sets of documents existed.
  
 This resulted in the decision not to include them (in their current form). I’m not sure that the case is strong enough to merit revisiting that conclusion.
  
 Best regards
  
 Mike

   Hi Mike
 
   
 
  It might be worth it to loop the member of your team who felt it necessary for the EU to diverge from the WCAG2ICT on those specific issues... we did agree on the WCG2ICT that a "set of documents" would not be common in the document world, but it did work when applied to documents, which facilitated consensus on the WCAG2ICT for the entire adoption of WCAG to Software and documents. 
 
   
 
  I often find in standards, as you may have experienced, that sometimes just sitting down and talking together helps us unify and make stronger global standards that are not splintered. I'd be keen to sit down with your technician and see if we can come together.

 I certainly wouldn’t recommend a solution that ignores those requirements. As I said, I wish you luck in getting a good solution to enable you to include them. If you succeed I, for one, would push to have this solution incorporated in any future update of EN 301 549!

 Subject: RE: DPUB Set of Web Pages
 
 
    
 Yes, this is interesting, but I'm not sure how to respond. As we work to a web publication definition, there are challenges we'll need to address, but I can't see how we could develop a specification that ignores wcag requirements. You absolutely have to have multiple ways to access the pages of a publication, for example. In EPUB, the reading system facilitates seamless navigation from document to document through the spine (metadata about the order). There is also a required table of contents, and publications often have other forms of navigation, like indexes, access to static page break locations, search functionality through the reading system, etc. I'm fully expecting that we won't compromise anywhere, but details of the pitfalls you encountered would be helpful.

    Hi Matt
 
   
 
  I think including a epub example in a set of web pages wouldn't preclude a more specific definition of epub at a later time, or even in a later version of WCAG ... on the other hand, maybe we could introduce a new term in 2.1 if we have it very soon.
 
   
 
  It just seems to me that "a set of web pages" and inherent in that the "web page definition" of the base URL and associated assets, is a perfect short term definition that would accomplish what George mentioned about working epub into the web page framework so that the WCAG Success Criteria can explicitly apply to epub. 
 
   
 
  Although just the fact that they sit at a URL already allows WCAG Success Criteria to apply to epub, and WCAG2ICT applies when its offline.

    Thanks, David, this is a good start. I'd just suggest that we keep any definition of a web publication agnostic to specific formats.
  
 As Tzviya mentioned on the call, the DPUB group will be taking up the issues from yesterday on their next call, so we'll have more to say about example wording and metadata after we can involve the full group.

 Subject: DPUB Set of Web Pages
    
   Note: DPUB members, this is my personal opinion, not speaking for WG
 
   
 
  Today we discussed ways that we could role a DPUB package into our definition of web page.
 
   
 
  DPUB packages have more than one URL, and as such cannot be considered under our current definition as a web page. However, we have a useful definition in WCAG which lends itself ideally to a DPUB document. That is a "Set of Web Pages"
 
   
 
  set of Web pages
  collection of Web pages that share a common purpose and that are created by the same author, group or organization
   Note: Different language versions would be considered different sets of Web pages.
 
 
  https://www.w3.org/TR/WCAG20/#set-of-web-pagesdef
 
   
 
  We could add something like this to the definition
 
   
 
  "Example: An epub publication has a table of contents and 25 separate URLs representing each chapter of a digital book."
 
   
 
  If the DPUB team has Success Criteria they would like to propose for WCAG, for DEC 1st, I suggest they submit them using this definition. For instance, if they want ways to link from a TOC to another chapter of the document and back, they could propose something like:
 
   
 
         "Every link from a Table of Contents in a set of web pages has a corresponding link back to the Table of Contents"
 
                  
 
  Of course this SC  is just off the top of my head but it gives an idea of how this type of SC could be written with this language.
 
   
 
  =============
 
  Also we discussed meta data as a means of reporting conformance. WCAG 2 has a discussion of meta data in Appendix C which may be useful.
