Hello,
I was about to publish my first illustrated ebook but I hit a wall as it refuses to validate with Itunes Producer... It's rather frustrating as my book displayed just fine when I tested it on an Ipad - just transfering the epub file and opening it in Ibooks.
Could you please help me pinpoint what's wrong and what I should modify in my epub ? I am pasting below the error messages given to me by Epubcheck+ Itunes Producer and attaching the content.opf along with a screenshot of what my epub folders look like. (if anything else is needed, just let me know !).
Thanks a million in advance !
Note : I only have a super basic of knowledge of html / epub specs. The epub was created through Indesign+Epubcrawler script, with an intermediary tweak of the content.opf file. It is a fixed layout epub (full screen pictures that mix text & images, a sort of graphic novel)
EPUBCHECK errors :
ERROR: test ipad original.epub/OEBPS/content.opf(7,13): The prefix "dc" of element "dc:title" is not bound.
ERROR: test ipad original.epub/OEBPS/content.opf: The prefix "dc" of element "dc:title" is not bound.
ERROR: test ipad original.epub/OEBPS/content.opf: unique-identifier attribute in package element must reference an existing identifier element id
Then I get a series of warnings which I really don't understand as they concern files that *are* mentioned in the OPF (but maybe not with the right syntax ?) . I'm not listing all of them but it looks like this :
WARNING: test ipad original.epub: item (OEBPS/p2.css) exists in the zip file, but is not declared in the OPF file
WARNING: test ipad original.epub: item (OEBPS/p1.xhtml) exists in the zip file, but is not declared in the OPF file
WARNING: test ipad original.epub: item (OEBPS/images/BG_p3.jpg) exists in the zip file, but is not declared in the OPF file

ITUNES PRODUCER basically lists the same errors and the summary of the issues reads like this :
[2014-12-02 16:06:52 CET] <main> ERROR: ERROR ITMS-9000: "Unable to parse opf file: content.opf" at Book
[2014-12-02 16:06:52 CET] <main> DBG-X: The error code is: 1102
Package Summary:
1 package(s) were not uploaded because they had problems:
/Users/nikoadminlocal/Desktop/project.itmsp - Error Messages:
ERROR ITMS-9000: "Unable to parse opf file: content.opf" at Book
Any ideas ?
