EPub for Ingram Spark

PKTC · 03-30-2016, 07:05 AM

I want to make my books available through Ingram Spark. They require EPUB 3 (not 3 enhanced). I converted a trial book to EPUB in Calibre (latest version) and tested it with the validator specified by Ingram Spark. The list of errors was enormous. Can anyone help me with this, please?

Download Sigil and install the ePub3 output plugin. If the original ePub2 book passed ePubCheck so should the converted version.

As Calibre doesn't support ePUB3, I am not surprised. Like Doitsu said, download Sigil with the ePUB3 output plugin.

Since you don't specify the source format, can you please tell us? Somehow I suspect that you don't have and ePUB2 yet and are trying to convert to an ePUB from another source. Be aware that the outcome of such conversions can vary from bad to good, all depending on the source.

what is EPUB3 different from "3 enhanced"?

Enhanced ePub 3 uses features not available in ePub 2 such as left-to-right text.

Thank you for your reply. My books are stored in Calibre which then allows output to various formats, including what they call "EPUB" without any further explanation of what version that means. My hope is to export in EPUB from Calibre then convert it to EPUB3

PKTC · 03-31-2016, 02:44 AM

OK, I've downloaded and installed sigil and the EPUB3 plugin per the recommendations above. It produced an EPUB3 that failed EpubCheck. I went back to the source, an EPUB file exported from Calibre. It too produced an EPUB that failed EpubCheck. EpubCheck reports that the Epub file from Calibre is v. 2.0.1. Now where to go. Half our catalogue (we are a publisher) is in Calibre and we would like an easy way to go to Epub3 rather than have to do the whole thing over again.

Is "Enhanced ePub 3" a Ingram Spark way to define it? In IDPF there is not any "Enhanced ePub 3", only EPUB3.

There is no definition of "enhanced ePub3" in the official ePub3 specs. Many publishers use "enhanced ePub3" to refer to interactive ePub3 text books generated by Apple tools.

Most likely the Ingram people themselves don't know what "enhanced ePub3" is. IMHO, making ePub3 books a requirement doesn't really make sense for publishers, unless they specialize in interactive ebooks.

Post a list of the ePubCheck error messages that you got for the original ePub2 files and the ePub3 files.
Some errors can be easily fixed by running a simple regex search in Calibre and/or Sigil.
You might also be able to address these issues by modifying the source files that you used to generate the ePub2 files with Calibre.

Well, if I could use EPUB3 I'll be happy anyway for more semantic tags and some nice things in CSS.

First fix the ePUB2 before converting to ePUB3. You can't expect a faulty ePUB2 convert to a working ePUB3... If you are a publisher, ensure you a have someone with more than decent knowledge on XHTML/CSS and the ePUB specifications. Otherwise fixing and supporting ePUB2 can be quite a challenge.

When did IngramSpark shift over to ePUB3? I had an ePUB go through them mere days ago, for a client, and it's absolutely ePUB2. Did someone over there get confused again, and mistake ePUBcheck 3.01 with "ePUB3?" (Happens all the time...)

You may want to double-check. Before you give yourself brain-damage.

Thanks for the various replies.

I've worked out all the problems with converting my files to EPUB2 and 3. I can validate the resulting Epub2 with Epubcheck successfully. After working on EPUB3 with Sigil for a while, I got to the point of no errors at validation but I am getting this type of warning, with one warning for each line of the manifest that lists the document sections:

WARNING OEBPS/content.opf 13 140 XHTML Content Document file name 'OEBPS/Text/Practical_Guide_to_the_Two_Truths.htm' should have the extension '.xhtml'.

I have tried going into the content.opf file and manually changing each of the lines per the warning message, but that makes things worse, producing errors at validation. I have tried rebuilding the manifest using the option for doing so in Sigil but that just gets me back to the set of warnings explained above. Any ideas on how to solve this? If I can through this, I should be done, I think.

According to their FAQ.

Quote:

INTERIOR (EPUB)

Format: EPUB 3.0 required. We cannot accept enhanced EPUB 3 files at this time.

Simply change the file extension of Practical_Guide_to_the_Two_Truths.htm to xhtml in the Book Browser window:

Code:

Practical_Guide_to_the_Two_Truths.xhtml

Sigil should automatically update all references to this file.
