Ace by DAISY
File accessibility and proper file structure are critical for every project in the Well-Formed Document Workflow.
Ace checker will report warnings and violations related to missing accessibility metadata as well as head-level hierarchy and color contrast issues. A fully compliant ePub file will have no violations or warnings.
Examples of hierarchy errors include:
- The use of eh instead of ah for heads in Notes sections
- A chapter starting with a b-head (bh) or a c-head (ch)
Note: Ace checker cannot currently detect the presence of alt text, but its inclusion is strictly required for a fully compliant ePub.
Scribe provides access to the Ace by DAISY app in the External Tools Menu in the Digital Hub.
