EPUB3 Fixed Layout Errors... OPF Version Not Found & Prefix Already Specified

pressmatters · 10-03-2014, 07:04 PM

Hello all,

I am building a fixed-layout epub for ibooks and have two errors when I run epubcheck 3.0.1:

EXCEPTION: /Users/TechIntern/Desktop/epubbase/epubbase.epub/OEBPS/content.opf: Attribute "prefix" was already specified for element "package".
ERROR: /Users/TechIntern/Desktop/epubbase/epubbase.epub/OEBPS/content.opf: Version not found

The opening section of the offending file looks like this:

Code:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<package version="3.0" unique-identifier="PrimaryID" xmlns="http://www.idpf.org/2007/opf" prefix="rendition: http://www.idpf.org/vocab/rendition/#" prefix="ibooks: http://vocabulary.itunes.apple.com/rdf/ibooks/vocabulary-extensions-1.0/">
	<metadata xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:opf="http://www.idpf.org/2007/opf">

Any help is greatly appreciated. I've been hitting my head against a brick wall for hours now!

Prefix is entered twice on the same line. I am not sure epubcheck will work properly with the iBook version of fixed-layout.

You can combine the two prefix-declarations into one:

Code:

prefix="rendition: http://www.idpf.org/vocab/rendition/#  ibooks: http://vocabulary.itunes.apple.com/rdf/ibooks/vocabulary-extensions-1.0/"

No idea what could be wrong about the version-error though.

ePubCheck will validate an EPUB3 with Fixed layout just fine if you follow the rules
