djiffy 0.8.0

Django app for IIIF Presentation book content

Django application to index and display IIIF Manifests for books

djiffy is intended to be a reusable Django application for working with digitized book content provided via IIIF Presentation manifests. This is an alpha version and it does not yet support the full IIIF Presentation specification.

Note

djiffy is tested against Django 3.0-3.2.

Code documentation is available at https://princeton-cdh.github.io/djiffy/

Installation

Use pip to install:

pip install djiffy

You can also install from GitHub. Use a branch or tag name, e.g. @develop or @1.0, to install a specific tagged release or branch:

pip install git+https://github.com/Princeton-CDH/djiffy.git@develop#egg=djiffy

Configuration

Add djiffy to installed applications and make sure that django.contrib.humanize is also enabled:

INSTALLED_APPS = (
    ...
    'django.contrib.humanize',
    'dal',
    'dal_select2',
    'djiffy',
    ...
)

Include the default djiffy urls at the desired base url with the namespace djiffy:

urlpatterns = [
    ...
    url(r'^iiif-books/', include('djiffy.urls', namespace='djiffy')),
    ...
]

Run migrations to create database tables:

python manage.py migrate

Note

The templates included require that you have a url configured with the name site-index.

If you are need to use djiffy to access manifests that require an authorization token, use DJIFFY_AUTH_TOKENS in your project settings to configure each domain that requires an auth token. The configuration should be formatted like this:

DJIFFY_AUTH_TOKENS = {
    'example.com': 'myauthtoken',
}

Usage

Import IIIF content using the import_manifest manage command. This command can take an IIIF Collection or single Manifest, via local file or URL. Imported content can be viewed in Django admin.:

python manage.py import_manifest http://url.for/iiif/manifest
python manage.py import_manifest /path/to/local/collection

Development instructions

This git repository uses git flow branching conventions.

Initial setup and installation:

• recommended: create and activate a python 3.5 virtualenv:

  virtualenv djiffy -p python3.5
  source djiffy/bin/activate

• pip install the package with its python dependencies:

  pip install -e .

Unit Testing

Unit tests are written with py.test but use some Django test classes for convenience and compatibility with django test suites. Running the tests requires a minimal settings file for Django required configurations.

• Copy sample test settings and add a SECRET_KEY:

  cp ci/testsettings.py testsettings.py

• To run the tests, either use the configured setup.py test command:

  python setup.py test

• Or install test requirements and use py.test directly:

  pip install -e '.[test]'
  pytest

Documentation

Documentation is generated using sphinx. To generate documentation, first install development requirements:

pip install -r dev-requirements.txt

Then build documentation using the customized make file in the docs directory:

cd sphinx-docs
make html

As of v0.7.3, documentation is automatically built with GitHub Actions and published using GitHub pages.

Adding license images

When adding new license image SVG files to this repo, add id="licenseimg" to the <svg> element of each. This allows djiffy users to embed the SVG inline with a <use> tag, with its href attribute pointing to #licenseimg.

If the image will need to be recolored for different backgrounds, as in the case of the rightsstatement_org/ SVG icons, you can enable this for up to two tones in each SVG. To do this, set fill attributes on paths to fill="inherit" (controlled by the fill CSS property) or fill="currentColor" (controlled by the color CSS property).
