Can't publish a ebook on feiyr.com. Error in opf file.

ZHMEN · 05-31-2023, 05:35 AM

Hello! I can't publish a ebook in epub formay on feiyr.com.

Error message after posting:

Error / Cover: No cover file was defined in the OPF file (by in section or by properties="cover-image" in section).

The result of checking epub by validators:
Validation for current epub: 0 fatals / 0 errors / 0 warnings / 0 infos
Your epub is valid according to EPUB version 2.0 rules.

properties="cover-image" - this is for epub 3.0 format metadata structure, but not valid for 2.0

What is wrong with my opf file?
Thanks in advance for any help!

my opf file (content.opf)

You are making an ePub2 according to the version # at the top of your opf, so make sure you are following those rules. If you use Sigil or Calibre to add your cover then this should all be done automagically. But you should see something referencing 'cover' in each section (metadata, manifest, spine, and guide) of your opf. Something along the lines of:

Code:

<?xml version="1.0" encoding="utf-8"?>
<package version="2.0" unique-identifier="BookId" xmlns="http://www.idpf.org/2007/opf">

  <metadata xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:opf="http://www.idpf.org/2007/opf">
    <dc:identifier opf:scheme="UUID" id="BookId">urn:uuid:6291c88b-0401-4263-8f9e-18c3aaec004a</dc:identifier>
    <dc:language>en</dc:language>
    <dc:title>[Title here]</dc:title>
    <meta name="cover" content="cover.jpg" />
  </metadata>

  <manifest>
    <item id="ncx" href="toc.ncx" media-type="application/x-dtbncx+xml"/>
    <item id="cover.xhtml" href="Text/cover.xhtml" media-type="application/xhtml+xml"/>
    <item id="cover.jpg" href="Images/cover.jpg" media-type="image/jpeg"/>
  </manifest>

  <spine toc="ncx">
    <itemref idref="cover.xhtml"/>
  </spine>

  <guide>
    <reference type="cover" title="Cover" href="Text/cover.xhtml"/>
  </guide>
</package>

Your opf has 'cover-image' in the contents of the metadata section, and the ID in the manifest section. You need to reference the image name.... cover.jpg

Also make sure your references are pointing to the correct location. eg. If you have your images in an Images folder then the reference would be "Images/cover.jpg"

Cheers!

Actually, you need not create an id from a file name. Sigil does it that way because if filenames are unique that the id will be unique.

So IF all links are truly valid, then feiyr.com's validator is broken for epub2. Either feiyr.com wants an epub3 instead of an epub2, or using the id "cover-image" which incidentally matches an official epub3 manifest property name "cover-image") is somehow confusing their validator.

This all assumes ALL your opf href entries are valid! If not, just fixing them should help.

Try as Turtle suggested, changing the metadata content to be match its filename or any other unique id that you set as the id in the cover.jpg manifest entry. Anything but "cover-image".

If that helps, then the bug is in there validator. If not, then check if feiyr.com only accepts epub3.
