Now that EPUB 3.2 has been published, what's next for EPUB? This will be
discussed in the CG call this Thursday (agenda forthcoming) but it's a big
question (or a bunch of questions), and I hope discussion will extend
beyond the CG calls. Some thoughts:

1. How should EPUB 3 be maintained? I personally thing EPUB 3.X is a good
candidate to become a living standard in the manner of HTML. I also wonder
the specs be easier to read and maintain if written in a different way, for
example Matt's suggestion to separate reading system conformance from
content conformance?

2. What, if anything, needs to be added or changed in EPUB 3? There are
some possible changes that would not invalidate any existing EPUB, such as
adding opus as a core media type or allowing the HTML serialization. But
what new features are driven by business needs? And how do we balance a
desire for new features against the costs of supporting them? There is
value in a stable spec, and I don't want to spend the rest of my life on
EPUB 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10…

By chance, I ran across the original EPUB 3 Charter (
http://idpf.org/epub/30/wg-charter) this morning. Written in 2010, it
described fourteen goals for what turned out to be EPUB 3.0. Nine years
later, which of these goals have we met? What new goals would we add?

3. What should we do about all the EPUB satellite specs? The IDPF published
nearly a dozen specs, which have largely not been implemented by reading
systems or used by content authors. Should some of these be revived? Should
some of these be abandoned?
