RE: DPUB Set of Web Pages

Bear in mind that there's technically no such thing as a set of web pages on the web that is also an EPUB; EPUB is currently a packaged format. Formalizing an exploded version of EPUB would have been in the next major revision but has evolved into the DPUB work. The DPUB model, at this stage, is a set of web pages that can be taken offline and/or made portable. That's why our focus is on the publication as a set of web pages and not on a specific implementation. I think we can frame an example without naming a technology so it applies well to all cases.

 

If I were to take a stab at wording, I'd probably propose something like the following:

 

"Example: A publication is split across multiple Web pages, where each page contains one chapter or other significant section of the work. The publication is logically a single contiguous unit, and contains navigation features that enable access to the full set of pages."

 

But I'd still like to get the dpub folks to weigh in with any thoughts, too.

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  <https://www.w3.org/TR/WCAG20/#webpagedef> 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.
