For implementation & testing:

• Exploded EPUB
• Packed EPUB
• OPDS

Also, there is a localization JSON available from W3C: https://github.com/w3c/publ-a11y/blob/main/UX-Guide-Metadata/draft/localizations/en-US/display_guide_vocabulary_w3c_en-US.json

Future localizations to be added.

It is intended to work with the techniques documents (Code IDs of the techniques are Keys of the JSON).

Example:
THEN display "Appearance can be modified". Is refering to "visual-adjustments-modifiable": {

A display of JSON values is available at https://rawcdn.githack.com/w3c/publ-a11y/91141c948fcb1b40ed13dc0b58567307a44474a4/UX-Guide-Metadata/draft/localizations/index.html

Thorium should use Compact sentences with no titles for categories and keep things as simple as a list.

Example:

• Appearance can be modified
• Not fully readable in read-aloud and braille
• Navigation by table of contents, index, landmarks, and page list
• This publication meets minimum accessibility standards

The guide is still being refined by editors.

An exemple processor is available from a dedicated daisy repo

Our Rare_EPUB_test_suit/package.opf
produces the following output:

Visual adjustments

Appearance can be modified

Supports nonvisual reading

Readable in read aloud or dynamic braille

Conformance

This publication is certified by EDRLab

The certifier's credential is Certifier credential

Detailed Conformance Information

This publication claims to meet EPUB Accessibility 1.1 WCAG 2.1 Level AA

The publication was certified by EDRLab with a credential of Certifier credential

Prerecorded audio

Audio only

Navigation

Navigation by table of contents, index, supports page navigation, and headings

Charts, diagrams, math, and formulas

Accessible chemistry content

Accessible math content

Hazards

No hazards

Accessibility summary

This is the accessibility summary. This EPUB is for testing purposes, accessibility metadata presented are not true but only present to check how they would display into the reading system.

Legal considerations

No legal considerations

Additional accessibility information

IMHO our implementation should differ to avoid titles with only one element and include detail element for more information. Something like

Reading modes

Appearance can be modified

Readable in read aloud or dynamic braille

Prerecorded audio

Navigation

Navigation by table of contents, index, supports page navigation, and headings

Additional accessibility information

Contents

Accessible chemistry content

Accessible math content

Hazards

No hazards

We could even get ride of titles (Reading modes, Navigation, etc.)

Should we have a Readium component for that?

I suggest assigning myself to update locals for now (

Swift implementation mapping for reference.
@mickael-menu commented that RWPM is so close to EPUB that applying the EPUB techniques was the easiest path to follow.

Choices made on the way:

• sentence construction that includes concatenation was ignored because of Localized placeholders #688 issue. That concerns certfier prefixed information in 3.2 Conformance
• As the order is free to implementors, it was decided to use the following: Ways of reading, Navigation, Rich content, Hazards, Conformance, Legals, Additional and Summary.
