But this would be bigger than one prefix. If rendition: isn't recognized, then a11y: and epubsc: aren't going to be recognized, either. Maybe others I'm not thinking of. It might be the rdfa spec that says the predeclared prefixes are a convenience but authors should strongly consider always declaring explicitly. Including similar guidance, certainly at least until vendors/reading systems support the prefixes, seems reasonable enough (and noting it in errata). The only pitfall is that if it is related to using an older version of epubcheck under the hood, redeclaring the original reserved prefixes might trigger a different error. We might have to give guidance to the applicability to "new" prefixes, without locking in forever what those are. Matt From: eb2mmrt@gmail.com [mailto:eb2mmrt@gmail.com] On Behalf Of MURATA Makoto Sent: May 24, 2017 8:25 PM To: Dave Cramer <dauwhe@gmail.com> Cc: public-epub3@w3.org Subject: Re: EPUB3 CG: Save the Date (June 1, 16UTC), Call for Agenda Items Dave, Apple iBook does not recognize a reserved prefix(*) which was introduced in EPUB 3.0.1. If this prefix is explicitly declared, iBook has no problems in handling it. But if it is not, iBook reports an error. Since this prefix is predefined in EPUB 3.0.1, this behaviour does not conform to 3.0.1. Apple turned down the request by KADOKAWA to change this behavior. * http://www.idpf.org/epub/301/spec/epub-publications.html#sec-metadata-reserved-vocabs I am personally sympathetic to Apple, as additions of reserved prefixes causes troubles to existing RSs. I thus propose to add a warning about this issue and a recommendation to explicit declare this prefix by publishing an erratum to EPUB 3.0.1 and 3.1. I hope that this topic can be discussed in the CG.

We would welcome suggestions for agenda items. Two ideas: [1] Education: getting the task force up and running, and finding one or more volunteers to lead the effort. [2] Rendering: I've started sketching out some thoughts on full bleed images in EPUB on the wiki: https://github.com/w3c/publ-cg/wiki/Rendering. We'd love to see more ideas, use cases, examples, and especially feedback from reading systems. What topics would you like to discuss? We'll send out the phone/webex info once we have a draft agenda. Thanks! Dave Cramer -- Praying for the victims of the Japan Tohoku earthquake Makoto
