ACE notes "serious" error for missing a11y metadata in EPUB3

Closed this issue · 2 comments

Expected Behavior

When running the dtbook-to-epub3 script on DAISY books, the EPUB3 result should have an OPF file with the required accessibility metadata properties that ACE designates as "serious" when missing:

  • metadata-accessmode
  • metadata-accessibilityfeature
  • metadata-accessibilityhazard

Actual Behavior

Running ACE against the EPUB3 output generates a report pointing out the missing properties.
"a11y-metadata": { "missing": [ "schema:accessMode", "schema:accessibilityFeature", "schema:accessibilityHazard", "schema:accessibilitySummary", "schema:accessModeSufficient", "a11y:certifiedBy", "a11y:certifierCredential", "a11y:certifierReport", "dcterms:conformsTo" ], "empty": [], "present": [] },

Steps to Reproduce

The sample book in #674 exhibits this issue, so refer to the EPUB3 output from that.

The ACE report was then generated with this:
$ ace --subdir --silent --outdir ace_sherlock The_Adventures_of_Sherlock_H.epub

Environment

  • Operating system: Linux 64-bit
  • DAISY Pipeline 2 version: 1.14.7
  • Interface: web service API
  • ACE: 1.3.1
