Re: [docbook-apps] EPUB3: how to use base.dir ?

[Carlos Araya <carlos.araya@gmail.com>]

Thomas:

The build file I use was working without errors until I made the change. 

The problem with generating the content zip file is not just validation. Either before or after I validate the file I will still have to generate the zipped epub file to deliver so, to me, the problem is still there and it wasn't there before. 

I use JIng to validate the docbook file before transformation and it reports no errors. 

I work with the following customization layer

<?xml version='1.0'?>
<xsl:stylesheet
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

    <xsl:import href="">
    <!-- Additional Stylesheet-->
    <xsl:param name="html.stylesheet" select="'carlos-new.css'"/>

    <!-- add DC metadaa elements -->
    <xsl:param name="epub.include.optional.metadata.dc.elements" select="1"/>

    <!-- Kindle extensions -->
    <xsl:param name="kindle.extensions" select="1"/>

    <!-- Use graphics for admonitions? -->
    <xsl:param name="admon.graphics" select="1"/>

    <!-- Callouts -->
    <xsl:param name="callout.graphics.extension">.png</xsl:param>
    <xsl:param name="callout.graphics.path">images/callouts/</xsl:param>
    <xsl:param name="callout.graphics" select="1"></xsl:param>

    <!-- Control Chunking Behavior -->
    <xsl:param name="chunk.section.depth" select="0"/>
    <xsl:param name="chunk.first.sections" select="0"/>

    <!-- Additional items to add to package.opf-->
    <xsl:template name="user.manifest.items">
        <item xmlns="http://www.idpf.org/2007/opf" id="font1" href="" media-type="application/vnd.ms-opentype"/>
        <item xmlns="http://www.idpf.org/2007/opf" id="font2" href="" media-type="application/vnd.ms-opentype"/>
        <item xmlns="http://www.idpf.org/2007/opf" id="font3" href="" media-type="application/vnd.ms-opentype"/>
    </xsl:template>
</xsl:stylesheet>

According to the snapshots.docbook.org page, the last version is built on
April 17. This looks not as the latest snapshot release. ;-)

However, I've tried to transform my cookbook project into EPUB3 and received
validation errors too (but they are different). But this is another story.

Right, that's correct now.

Tip: You don't need to create the ZIP archive and pass it to epubcheck. You
can start the validation process right after xsltproc wrote the directories
without creating the ZIP archive.

For example, if you've used foo/ as base.dir, invoke epubcheck with this
option after the transformation step:

 $ epubcheck foo/ -mode exp

It is even possible to validate only parts of the EPUB (directory), also with
the -mode option:

 mo    = Media overlays
 nav   = Navigation document
 opf   = package document
 svg   = SVG content
 xhtml = XHTML content

The -version option specifies with EPUB version to validate (the values can be
either 2.0 or 3.0).

This indeed looks strange. However, I didn't get such validation errors. I've
used the last public stable release (1.78.1) and the snapshot from docbook-
xsl-snapshot.tar.bz2 file, both with success.

Do you use a customization layer?
