Publish Plone content in epub form
Project description
A product which allows you to import in Plone epub files.
Contents
Introduction
EEA Epub product allows you to import in Plone epub files. On upload, Epub content will imported as Plone folders, files, images and documents.
Export to Epub is also available.
As of version 4.3 epub files created with Adobe InDesign CS4 and Sigil are tested and known to work with this package, previous versions of this package only supported epubs created with InDesign.
Main features
EEA Epub features:
Imports epub files as Plone content.
Stores the original epub in the main folder for easy retrieval.
Exports the Plone content back into an epub.
Clean filename as you import the epub and they contain characters that wouldn’t be allowed as a Plone id. This behaviour is on by default but it can be disabled by unchecking the boolean flag at portal_properties/site_properties clean_epub_file_names. If you find that the Document Pages added by the Epub process has broken links try to re-upload without this boolean flag.
Possibility to temporarily disable dynamic ePub creation by adding an item called ‘action-download-epub’ within context
Epub compatibility
EEA Epub makes the following assumptions about the loaded epub:
You don’t use unicode or other special characters into the name of the epub, images or links
You’ve created the epub with “Adobe InDesign CS4” or “Sigil” which uses some standards for the following:
The table of contents is named toc.ncx and is placed inside OEBPS
Book text & images are placed inside the folder OEBPS or other folders that are children of OEBPS
Items ids doesn’t contain the following characters . / ( if possible stick to letters, numbers and - _ )
Best practices when creating an epub:
Chapter names should not be all uppercase or use special characters
Image names should not contain spaces, periods, / or other special characters
Debugging
At this moment any errors that would appear on the site are surpressed with a info message.
If you want to see the detailed error check the Plone instance log usually found in buildout-folder/var/log.
Installation
The easiest way to get eea.epub support in Plone 4 using this package is to work with installations based on zc.buildout. Other types of installations should also be possible, but might turn out to be somewhat tricky.
To get started you will simply need to add the package to your “eggs” and “zcml” sections, run buildout, restart your Plone instance and install the “eea.epub” package using the quick-installer or via the “Add-on Products” section in “Site Setup”.
You can download a sample buildout at:
https://svn.eionet.europa.eu/repositories/Zope/trunk/eea.epub/buildouts
Getting started
From “Add new” menu select “EpubFile” and upload an epub file.
Custom permissions
Custom permissions added by this package
Can download ePub (eea.epub.download)
Assign this permission to roles that you want to be able to download content as ePub Default: Owner, Manager, Editor
Can customize ePub (eea.epub.customize)
Assign this permission to roles that you want to be able to contextually customize the output ePub look and feel Default: Manager, Site Administrator
Disable ePub export
You have the possibility to temporarily disable dynamic ePub export contextually by adding a static ePub file (or a Python Script, Page Template, etc) within context called action-download-epub. This way /download.epub will return this file instead of generating one based on context data.
