The International Digital Publishing Forum, a standards organization for the digital book publishing industry and champion for the EPUB3 e-book format, will be releasing a test suite for e-readers to determine how EPUB3 compliant they are.
The move is part of a larger campaign by the IDPF to make EPUB3, an e-book format built on the ubiquitous website coding language HTML-5, the standard format for e-books. While many publishers have come out in support of standardization and of the EPUB3 format in particular, popular retailers that have to build their e-readers to support functionality that EPUB3 allows have yet to universally adopt both the concept of standardization and any particular format.
When loaded onto a particular e-reader, say iBooks, which supports much of EPUB3 functionality, the test suite will tell the user what EPUB3 functionality the e-reader supports, what functionality it doesn’t and to what degree.
“EPUB3 adoption will evolve based on the business constraints of the retailers and publishers,” he said, adding that the test suite is only one of the initiatives that the IDPF is working on.
In addition to iBooks, both Google and Kobo e-readers support some parts of EPUB3.
