The EPUB Working Group is currently considering ways to better align with the Open Web Platform (OWP), including introducing support for the non-XML serialization of HTML5.
Among the constructs defined in EPUB, however, are four extensions that extend the rendering capabilities of the OWP: switches, triggers, bindings and manifest fallbacks. A fifth, canonical fragment idenfitiers (epubcfi), enables linking within the EPUB zip container.
In addition to not working natively on the OWP, many existing EPUB 3 reading systems still do not support these extensions (see www.epubtest.org
Therefore, to help determine their continued support, we would appreciate your time to complete the following short survey on your use of them.
The deadline for submitting responses to this survey is December 15, 2015.
For more information about the EPUB 3.1 revision, please see the workplan (http://www.idpf.org/workplans/2015/epub/
