Validating and Conformance of EPUB (W)

Title slide: Validating and Conformance Checking EPUB
In our series of free weekly webinars November 3rd saw a session focused on the validation and conformance of EPUB content. When using the EPUB format a few simple steps can help highlight any issues and guide you on the path to creating more usable and accessible content.

Session Overview

Richard Orme introduced this session explaining that it’s not enough to create content in any format and simply hope it works on reading systems and that it can deliver accessibility. The three experts presenting this webinar looked at validating EPUB from their perspective angles.

What Is An Accessible EPUB?

Many publishers have switched to EPUB as their format of choice for their digital content workflow but, despite it being the format which offers the greatest opportunity for accessibility, some have missed the mark. By failing to include a table of contents, for example, or by not having a clear reading order, EPUB content was often disappointingly lacking in accessibility support. For an EPUB file to be accessible, the publisher must make the most of the features that the format offers.

An understanding of this together with knowledge of the legal requirements in your market are a good place to start an accessibility journey. Add to this an alignment with publishing and web standards and some technical research to provide a base of knowledge and publishers should be in a position to make the most of their EPUB workflow.

3rd Party Certification

Having a 3rd party certify your accessible content helps the publisher to navigate the standards and specifications and Charles La Pierre talked us through the Benetech Scheme, Global Certified Accessible (GCA), outlining the process required for a publisher to be certified. A score is attached and for content to be certified as Born Accessible, 80% is needed.

Developing Internal Standards

Internal standards help the publisher to narrow the technical landscape and make it relevant to their specific workflow. James Yanchak described how this is achieved at Taylor and Francis and explained how this has helped them to reach their accessibility goals. Any internal standard must adhere to the industry standard and it’s vital that training is offered to both in-house colleagues and external vendors.

Validating the EPUB

There are a number of tools which our panel recommended:

  • EPUBCheck – should be one of the first checks and if this is integrated into the workflow using the command line version then it becomes very straightforward.
  • Ace by DAISY – checks conformance of the EPUB to WCAG and offers a command-line version and a desktop version for one-off title checks
  • Ace SMART – to be used in conjunction with Ace and helps the user perform the manual checks that Ace identifies.
  • The DAISY Knowledge Base has been developed to help resolve accessibility issues and is constantly maintained.

All of these stages and checks are important to establish accessibility and “trust” in the end product. A reader needs to be able to trust the accessibility summary and metadata so that they can make the correct purchasing decisions.

Help Improve Reading Experiences for Everyone

Can you Help Change the World?

The accessibility of digital reading experiences has improved dramatically over recent years, but it is still incredibly difficult to identify a reading experience (app or hardware) which you know will work with the latest EPUB 3 publications, and with specific combinations of assistive technology to provide a fully accessible reading experience.

On EPUBtest, an initiative created by DAISY, IDPF and BISG, we are taking the guess work out of selecting a reading experience by applying a clear and consistent testing procedure to different reading solutions. This directly results in valuable feedback for developers, so they can identify where they might need to focus their efforts, as well as clear information for consumers and procurement specialists which allows informed purchasing decisions.

There are lots of different solutions and assistive technology combinations we would like to test, so we’re looking for your help.

If you are able to help with testing we have lots more information for you at the link below. We would also love your help in spreading the word, and inviting more people to learn more about the testing process.

Together we really can change the world!

Announcing Ace Beta Release

Announcing the First Beta Release of Ace, by DAISY, the Accessibility Checker for EPUB.

The DAISY Consortium are delighted to announce the first beta release of their new open source software tool – Ace – an accessibility conformance checking tool for EPUB 3 publications. This new tool will provide clarity for the publishing industry where accessibility can mean many things to many people. Based on the requirements specified in the new EPUB Accessibility Conformance and Discovery Specification 1.0, Ace has been designed to check packaged or unpackaged EPUB 3 files at any point in the publishing workflow process.

Specifically, Ace:

  • runs automated accessibility tests on EPUB content documents
  • extracts the publications metadata, and checks accessibility-related metadata
  • separates various document outlines (the Navigation Documents, ToC, the HTML etc) for side-by-side comparison
  • presents all the EPUB’s images and graphics and their associated accessibility descriptions in a consolidated table, for easier review
  • consolidates the various content features to facilitate human-driven accessibility audits
  • can be run as a command line tool, or integrated as a Javascript node module, or driven by an HTTP API

Reports on conformance can be output at all stages of the publishing process as user friendly HTML documents or machine readable JSON-LD data. This type of early feedback is particularly helpful with future conformance issues and for training in-house employees to include accessibility within their workflows. Third party suppliers can be required to implement Ace checking on EPUB files and provide reports for their publishers. The appropriate metadata will be available for content providers to announce their subsequent conformance.

This beta release is actively seeking feedback from technical experts in the publishing industry who are happy engaging with EPUB3 code and working through a command line interface.

Please note, this early release tool is testing the examination and content presentation processes, and through feedback the tool will be refined with a second round of beta testing, with a final mainstream release scheduled towards the end of the year.

Technical experts can get involved with the Ace Getting Started Guide.
