Connexions EPUB3 Library

Library for parsing and building EPUB3 files for connexions content.

Getting started

Tested on Ubuntu 18.04, packages needed: sudo apt install build-essential python-dev python3-dev libicu-dev python3-venv

Optional (Python3 virtualenv):

python3 -m venv env
source env/bin/activate
pip install -U pip setuptools

To install:

pip install git+https://github.com/openstax/cnx-cssselect2.git#egg=cnx-cssselect2
python setup.py install

Running tests

Either of the following will work:

python setup.py test
python -m unittest discover

Format notes

Order of documents

To enforcing order of contents, we use the navigation document rather than the Open Packaging Format (OPF), which supports a spine element that aids in epub reader in navigation order. The Connexions library does not use the spine for order. A navigation document is the authority on order of contents and which contents are document like. Anything not included in the navigation document is considered a resource.

Document encapsulation

Collections are easy because they will be sent across as individual OPF entries that contain the collection tree as navigation documents. In the case of publishing module documents without a collection, the navigation document will be flagged as a non-document item.
