Sigil's support for EPUB 3.1 specs, metadata
I was wondering when Sigil is going to support the EPUB 3.1 specification and especially the metadata part. Now Sigil creates refine attributes which is already deprecated (http://www.idpf.org/epub/31/spec/epu...ec-pkg-refines). Takes too much extra work to add correct metadata after editing ebooks in Sigil. I hope this will be fixed asap.

Sigil won't fully support EPUB 3.0 asap, let alone 3.1. Your best bet is to get someone to write an output plugin for Sigil if you need Sigil-created epubs to have 3.1 compliant metadata right now.

Does any device claim to support epub 3.1 yet?

ePub 3.1 is not yet finalized.

That said, given the changes we made to support Metadata in epub 2, and epub 3.0, we could probably add some support for epub 3.1 metadata (it is actually closer to epub2 than 3).
But my fear is that new users would opt for that format (3.1) and generate something that no device can actually read or use. |

Epubcheck does not support 3.1. And to my knowledge, Kindlegen does not support 3.1 as input, nor does iBooks export 3.1 (could be wrong, though). As to reader-support ... who knows? You can't buy 3.1 epubs to test with. Way too early to worry about supporting 3.1 metadata editing/saving it in my opinion. 3.0.1 was never fully embraced by anyone of any consequence, so I highly doubt the changes in 3.1 are going to bring anyone flocking to it any time soon.
I'm no proponent of zealous spec-compliance that comes at the expense of breaking mainstream relevance. The IDPF declaring which version of EPUB is "standard" has had very little effect on the reality of ebook publishing/editing in the past. How long has 3/3.0.1 been the official recommended "standard" being mostly ignored after all? ![]() Like I said ... maybe an output/input plugin for those who want to experiment with bleeding edge metadata specs?

Not only are there no commercial epub3.1 books, the IDPF hasn't officially released a single epub3.1 sample book on the IDPF samples github website because samples will be released "only after epubcheck validation of 3.1 files is made available."
Based on the commits since the latest epubcheck release, it doesn't look like the developers have added any epub3.1 specific checks to the epubcheck code base. I.e., it might take a while, until official epub3.1 sample files and an epubcheck version with epub3.1 support will be available. |

Are there any ePub 3.0 or 3.0.1 (for sale) that are not made backwards compatible with ePub 2 (that need an ePub 3 renderer to actually work)?

Yes. I've run into a couple of books downloaded from Kobo's site that used epub3 features requiring a rename to display correctly on Kobo's eInk devices. Kobo customer service does regard these as an issue. One of those ebooks required renaming to .fxl.kepub.epub to display semi-legibly -- I was going to say semi-readable but the poems are not really readable -- the sestina is not my favourite verse form.
