|EPUB 3 Support Grid|
The EPUB 3 Support Grid was designed to be a handy reference to what enhancements and features of EPUB 3 render correctly on the most commonly used devices, apps, and reading systems. The Grid represents results of reading system tests conducted by industry experts representing leading publishers, service providers, and technology vendors through the auspices of BISG's Content Structure Committee.
On February 19, 2014, through a partnership between BISG, the International Digital Publishing Forum (IDPF) and the DAISY Consortium, the EPUBTest.org website was launched as the new home of both the new EPUB 3 Support Grid and the EPUB Testsuite, a set of EPUB 3.0 files designed to enable anyone to systematically test an e-book reading system's support of various EPUB 3.0 features. These files were used to generate the results in the new BISG EPUB 3 Support Grid.
A major update to the Grid was completed in Spring 2015 to enable evaluation of support for accessibility across popular reading systems and assistive technologies. The update, which involved creation of a new set of EPUB 3 test documents specifically designed to assess fundamental accessibility support, makes it possible for anyone to test a reading system's support of accessibility features. To achieve a high fundamental accessibility score, reading systems should be able to perform basic functions like adjust font size and color, and text should be readable with a screen reader, self-voicing text-to-speech application, refreshable Braille display or assistive technologies designed for persons with dyslexia and other learning disabilities.
Until the Grid moved to EPUBTest.org, it was created and updated through independent research and reporting of the Content Structure Committee, and distributed as a Microsoft Excel Spreadsheet.Through use of the International Digital Publishing Forum (IDPF) EPUB Testsuite, a freely available collection of material created specifically for this purpose, the EPUB 3 Support Grid now provides more reliable, more comprehensive, and more up-to-date reporting on EPUB 3.0 support than was previously possible.
EPUBTest.org is a joint project between the International Digital Publishing Forum (IDPF), BISG, and the DAISY Consortium.
BISG thanks the International Digital Publishing Forum (IDPF) and the DAISY Consortium for their efforts in creation of the EPUB Testsuite and epubtest.org website.
BISG also thanks everyone involved in the initial development of the Grid, including YUDU Media for its contributions toward launching and conceptualizing the Grid.
Participating Companies include: Apex Covantage, Aptara, DAISY Consortium, Firebrand Technologies, Google, Hachette Book Group, HarperCollins, Ingram/VitalSource, International Digital Publishing Forum (IDPF), Iviago, John Wiley & Sons, Kaplan, Kobo Inc., Newgen, Penguin Random House, Safari Books Online, and Sourcebooks.
Recognizing the constantly shifting nature of digital publishing, the Content Structure Committee continuously updates the EPUB 3 Support Grid by adding more reading system evaluations, and updating the TestSuite files to test more features. Industry feedback is critical to keeping the Grid accurate, comprehensive, and up-to-date. We hope you'll join the dialogue and send in your comments and suggestions for improving and enhancing the Grid. Send your feedback to Kim Graff at email@example.com.
