Please provide the following details if possible or relevant:

  • Ace version: 1.3.2
  • Node version: v18.16.1
  • my OS: macOS 13.5.1

Ace currently flags EPUB publications for missing the 'schema:accessibilitySummary' metadata, while the EPUB Accessibility 1.1 standard indicates that this metadata is no longer mandatory (unlike EPUB Accessibility 1.0).

I've just noticed the same problem. https://kb.daisy.org/publishing/docs/metadata/schema.org/accessibilitySummary.html states that "If the summary does not offer any new information, the property can be omitted from digital publications."

A relevant statement is here: "accessibilitySummary metadata is now recommended (SHOULD), not required (MUST). The impact/severity is downgraded from serious to moderate."

Cf. also

ace/website/content/rules/epub.md

Line 9 in d56a8e1

* Missing metadata (impact = "moderate"): `metadata-accessibilitysummary`, `metadata-accessModesufficient`

EPUB accessibility additions (#9400)
3e7e6f0 
AccessModeSufficient and AccessibilitySummary are added.

These metadata are optional according to the EPUB Accessibility 1.1
standard, but ACE Daisy checker flags ebooks for missing them
(cf daisy/ace#389 and daisy/ace#400).

With this commit:

AccessModeSufficient is defaulted to "textual".
AccessibilitySummary can be included via the metadata block.
