In the best practices of the LIA Foundation we suggest publishers to insert, as the first element of the spine, an HTML file containing ONLY the cover image (in a rasterized format, not SVG because in our tests did not seem well managed by reading systems and screen readers). The alt-text of the cover picture shall contain the title, the author and any other relevant information present on the cover.

InDesign automatically creates, as the first HTML file of the EPUB, a file containing the cover image (in raster PNG format), but whose alternative text is insignificant: "1.png". Since many authors use InDesign, we could suggest to Adobe to automatically insert as alternative text at least the metadata title of the publication.

Oggetto: Re: [External] Re: New fundamental test book and covers

Good to see that accessibility of cover image has generated such a good
Clarifying the objective of this example sent by George.

In EPUB 3, cover was not accessible, we recognized it while development of
WP, and worked on making it accessible.

But EPUB 3.x is still lagging behind in this, so the objective is to provide
a "work around" for providing accessible cover in the existing environment
and existing state of reading systems. This is why the focus is on content
and not on updating reading systems.
It is difficult to come up with precise set of guidelines that will fit all
kind of EPUB publications. So, I think that our approach should be to define
some principles and allow content creators to develop best practices or
their content based on the principles. The principles that we discussed
The main principle is that a cover should solve the same purpose for person
with disability as it would do for any other person. for example, if a cover
image is used for marketing or generating interest in the potential readers,
the alt text should provide the same information to person with disability.
We encourage providing extended description, but it is not a hard
requirement because many publishers are still at the level of providing
meaningful alttext.

Title of the publication is exposed by reading systems, but metadata for
author may or may not be exposed in accessible way.
So, title and author should be provided to ensure that both are available to
readers. In the fundamental test book example, this info is the first piece
in alt text, which is followed by description of the image.

So, the intent is to provide a simple example build on a set of principles,
that can work in existing environment and existing reading systems.

With regards

I don't see a way to move beyond #3 (the status quo).

#2 - The complexities of making something optional on a title by title
basis, determining who is making it optional (publisher? Distributor?
Author? Reader?  Can a teacher make it optional for a textbook, but only for
specific classes? And on, and on...), and then inserting it into the reading
order (is it maintained in the same place for every book on subsequent
launches?  Can it be placed in arbitrary places?  Who determines this?),
while requiring a reading system to solve this in order to be conformant, is
too onerous.

#1 - The complexities of reverse engineering every AT and how to insert
non-standard alt markup for it to be treated like standard alt markup, and
requiring reading systems to do this (and maintain it as new AT emerge, and
existing ones update) in order to be conformant, is too onerous.

We are left with #3.

    I feel like metadata is a red herring here, because while it's one of
the use cases, the examples I gave (comics and picture books) are of cases
where the art should be described, as meaningful images. This means there is
a clear use case for cover alt being available to a book reader, regardless
of options for encoding metadata. This means there are three plausible

    1. Require reading systems to report any cover alt to AT, in some way,
perhaps with visually hidden text marked as doc-cover.

    2. Require reading systems to make the cover available to all readers,
as well as AT, as an optional page that can be read in the reading order.

    3. Tell content creators that if content from the cover is meaningful to
the reading experience, they need to including it as a page in the reading
order. (This is more or less what we do now.)

    Three is the status quo and results in an inconsistent and confusing
state of affairs.  Two is what I've always wished we do, but I have heard
plenty of others in publishing who dislike having the cover in the reading
order.  We ideally should do one or two.
