RE: Collections of web pages

Hi everyone,

Interesting discussion, ePub being a single & set of pages reminded me of high-school Physics, where light is both a particle and a wave!

Thinking through Peter’s 1st principles approach, and looking at the epub conformance guidance [1], for example:
> it is not sufficient for individual Content Documents to have a logical reading order if the publication presents them in the wrong order. Likewise, including a title for every Content Document is complementary to providing a title for the publication: the overall accessibility is affected if either is missing.

Considering the backwards compatibility, adjusting the scope of ‘set of web pages’ would mean somethings in 2.0/1 would be in scope there, and then out of scope in 2.2 (or vice versa).

How about a separate definition for epub (like) things? If it is essentially a sub-set of ‘set of web pages’, and can be applied (where applicable) to a ’web page’, that’s what we’re aiming for I think?

‘Set of web pages’ can apply to a sub-domain with a shared navigation. ePub is more constrained than that, so it does appear to be a sub-set of the current definition that also applies to a web page.

I’m not sure what to call it, but as a first draft based on Matt’s:
----------------
Electronic Publication
one or more web pages<https://www.w3.org/TR/WCAG21/#dfn-web-page-s> logically connected and with at least one defined reading order, such that whole would be incomplete or unusable if any were unavailable

Note: An electronic publication may be a single web page, or a set of pages.

Note: An electronic publication may be packaged and made available as a single web page (e.g., EPUB), but the packaging does not alter the nature of the publication.
----------------

Then we could include that in the scope of the new SC, and possibly refine a couple of the previous ones if it can be done in a backwards compatible way.
