Abstract

The European Accessibility Act (EAA) is an EU directive that establishes binding accessibility targets that must be met by many different types of products and services to strengthen the rights of people with disabilities to access goods and services, including ebooks, dedicated reading software, ereading devices, and ecommerce.

The EAA has been approved on 27 June 2019, should be implemented by EU Member States within 28 June 2022 and will enter in force from 28 June 2025.

This note aims to demonstrate that the technical requirements of the European Accessibility Act related to ebooks are met by the EPUB® standard.

The methodology used is mapping the requirements of the EU Accessibility Act related to ebooks to the EPUB Accessibility specification.

1. How EPUB conforming to EPUB accessibility guidelines cover European Accessibility Act requirements

EPUB is the standard format for the creation and distribution of publications in the digital publishing trade sector.

The specifications of the EPUB standard are based on the Open Web Platform: HTML, CSS, JavaScript and SVG are the core technologies used for content creation. The use of the latter means that EPUB publications can be written with a high degree of accessibility simply through the proper application of established web accessibility techniques, namely the Web Content Accessibility Guidelines (WCAG).

In order to outline how to make fully accessible EPUBs, the EPUB Accessibility guidelines have been drafted to address two key needs in the EPUB ecosystem:

Providing accessibility metadata facilitates informed decisions about the usability of an EPUB publication. Consumers can examine the characteristics of the content and decide whether an EPUB publication is appropriate for each need.

While it has always been possible to create EPUB publications with a high degree of accessibility, this document also establishes formal requirements for contents to be certified as accessible. These requirements provide EPUB creators with a clear set of guidelines for evaluating their content with respect to quality certification and enable it.

The EPUB Accessibility does not target a single version of EPUB (most commercially available publications are in EPUB 3 or EPUB 2 format). It is designed to be applicable to all EPUB publications conforming to any version or profile, including future versions of the standard.

This requirement is satisfied by EPUB Accessibility, section Discoverability.

2.1.1.2.1 (i)

Making the information available via more than one sensory channel

Out of scope: requirement for reading systems and Distributors.
