Updates to DAISY Ace and SMART Support EPUB Accessibility 1.1

Updates to DAISY Ace and SMART Support EPUB Accessibility 1.1

We are delighted to announce updates to Ace (Accessibility Checker for EPUB) and the SMART:

Ace By DAISY

Ace by DAISY is the free, open source EPUB accessibility checking tool, created to assist in the evaluation of conformance to the EPUB Accessibility Specification, helping your company meet industry requirements of accessible procurement, and enabling you to produce higher quality, standards conformant publications.

Designed to assist content creators at any stage in their workflow Ace is available as both a command line tool for workflow integration and a desktop App for quick testing of titles. Updates to both the Ace Command Line Tool (v1.2.7) and the Ace App (v1.1.5) have been published to support the new EPUB Accessibility 1.1 specification (“Conformance and Discoverability Requirements for EPUB publications”), currently a W3C Candidate Recommendation Draft dated 07 June 2022. Other maintenance fixtures and an update to the DAISY Knowledge Base are also included.

 The links for these updates can be found at:

A new version of the SMART tool is also available, allowing users to begin evaluating conformance to the new Accessibility 1.1 specification. This tool provides manual conformance checks necessary to ensure conformance with EPUB and WCAG requirements. Users will continue to have their reports initiated to check conformance with the EPUB Accessibility 1.0 specification, but they will be able to change the conformance settings to the 1.1 specification, which will then also let them choose WCAG 2.0 or 2.1 conformance. Accessibility 1.1 conformance will become the default when the specification gets to the next stage of Proposed Recommendation.

The other major changes with this update are:

  • Users to be able to filter the success criteria in the conformance tab by the type of content they’re checking
  • The conformance tab, which now includes a “Stats” box that shows how many success criteria have passed, failed, need checking, or are inapplicable.

Together, Ace by DAISY, SMART and the DAISY Accessible Publishing Knowledge Base provide the most complete method for accessibility conformance testing of EPUB publications.
