In an earlier video, I showed you how to apply epub:type semantics to objects in InDesign. It is now time to map those to the more meaningful DPUB ARIA roles.
The Digital Publishing (DPUB-ARIA) is an extension of the ARIA specification. It provides an additional set of publishing-specific roles for use with the ARIA role attribute.
The publishing roles are intended to improve the usability of publications both by providing assistive technologies (AT) with additional information about important structures and by ensuring that common publishing markup idioms are accessible.
