A parser for the Readium Web Publication Manifest (RWPM), Open Publication Distribution System 2.0 (OPDS 2.0), and Open Distribution to Libraries 1.0 (ODL) formats.

Note: This parser varys from the OPDS 2 + ODL spec in that it allows OPDS 2 + ODL feeds to contain non-open access acquisition links.

The spec defines an OPDS 2 + ODL feed as:

• It must be a valid OPDS Feed as defined in [OPDS-2] with one difference:
  • The requirement for the presence of an Acquisition Link is relaxed
  • Instead, each Publication listed in publications must either contain a licenses subcollection or an Open-Access Acquisition Link (http://opds-spec.org/acquisition/open-access)

The requirement that each link be an Open-Access Acquisition Link is overly restrictive, and prevents us from importing mixed OPDS2 and OPDS2 + ODL feeds. We relax the requirement to:

• It must be a valid OPDS Feed as defined in [OPDS-2] with one difference:
  • The requirement for the presence of an Acquisition Link is relaxed
  • Instead, each Publication listed in publications must either contain a licenses subcollection or an Acquisition Link (http://opds-spec.org/acquisition)

Usage

Install the library with pip

pip install palace-webpub-manifest-parser

Pyenv

You can optionally install the python version to run the library with using pyenv.

1. Install pyenv

2. Install one of the supported Python versions:

   pyenv install <python-version>
   

3. Install pyenv-virtualenv plugin

4. Create a virtual environment:

   pyenv virtualenv <virtual-env-name>
   pyenv activate <virtual-env-name>
   

5. Install the library

   pip install palace-webpub-manifest-parser
   

Setting up a development environment

Running tests using tox

1. Make sure that a virtual environment is not activated and deactivate it if needed:

   deactivate
   

2. Install tox and tox-pyenv globally:

   pip install tox tox-pyenv
   

3. Make your code prettier using isort and black:

   pre-commit run -a
   

4. To run the unit tests use the following command:

   tox -e <python-version>
   

   where <python-version> is one of supported python versions:

   • py38
   • py39
   • py310
   • py311

   For example, to run the unit test using Python 3.9 run the following command:

   tox -e py39
   

Releasing

Releases will be automatically published to PyPI when new releases are created on github by the release.yml workflow. Just create a release in github with the version number that you would like to use as the tag, and the rest will happen automatically.
