ckanext-dataontosearch
======================
Extension for integrating CKAN with DataOntoSearch.
DataOntoSearch is a project which aims to make it easier to find datasets, by using a domain-specific ontology to find similar datasets. The software is run as a separate server, which other projects like CKAN can connect to.
There are two separate plugins provided with this extension. ``dataontosearch_tagging`` provides a way of associating datasets with concepts in the ontology. (Each such association is internally called a "tag", which should not be confused with the traditional tags CKAN provide.) ``dataontosearch_searching`` provides an integrated way of searching using DataOntoSearch.
The extension adds a link you can follow when editing datasets. From there, you can change what concepts are connected to what datasets.
The extension also adds a link to the alternative search method. Following it lets you search using DataOntoSearch.
.. IMPORTANT::
This extension does not work by itself. It must be paired with a separately
deployed version of DataOntoSearch.
.. ATTENTION::
Both this and DataOntoSearch should be considered experimental. The majority
of the work is done by master students who are not affiliated with the
project after their involvement ends.
------------
Requirements
------------
This plugin was developed for CKAN version 2.8. We have not checked what other versions it works with, but it does use features introduced in version 2.7.
------------
Installation
------------
.. Add any additional install steps to the list below.
For example installing any non-Python dependencies or adding any required
config settings.
To install ckanext-dataontosearch:
1. Ensure that the ckanext-dcat_ extension is installed.
.. _ckanext-dcat: https://github.com/ckan/ckanext-dcat
2. Ensure that CKAN can accept multiple requests in parallel. For example, if
you use ``gunicorn`` to run your application, you could use the ``-w`` flag
to specify more than 1 worker: ``gunicorn -w 4 …`` (This is necessary
because this extension's request to DataOntoSearch might cause
DataOntoSearch to make a request back to CKAN, so the applications would end
up waiting for each other in a deadlock.) Note that the ``debug`` setting
must be set to ``false`` for CKAN to work in parallel.
3. Activate your CKAN virtual environment, for example::
. /usr/lib/ckan/default/bin/activate
4. Install the ckanext-dataontosearch Python package into your virtual environment::
pip install ckanext-dataontosearch
5. Add ``dataontosearch_tagging`` and ``dataontosearch_searching`` to the ``ckan.plugins`` setting in your CKAN
config file (by default the config file is located at
``/etc/ckan/default/production.ini``). Both are not required, any one of them can be used alone, but that is rather uncommon. They need to be listed after the ``dcat`` plugins.
6. Add required settings::
# Base URL where dataset_tagger is running
ckan.dataontosearch.tagger_url = https://example.com/tagger
# Base URL where the search for DataOntoSearch is running
ckan.dataontosearch.search_url = https://example.com/search
# The DataOntoSearch Configuration to use
ckan.dataontosearch.configuration = 5c7ea259c556bb42803fa17e
7. Restart CKAN. For example if you've deployed CKAN with Apache on Ubuntu::
sudo service apache2 reload
---------------
Config Settings
---------------
The required settings are described in the installation guide. In addition to those, you may specify the login used when connecting to DataOntoSearch::
# Username and password to use when querying and tagging datasets in
# DataOntoSearch (HTTP Basic Authentication)
# (optional, default: no credentials).
ckanext.dataontosearch.username = aladdin
ckanext.dataontosearch.password = opensesame
In addition, you can also tell the extension to use the autotagged similarity graph when searching, instead of the manual tags::
# Whether to use the autotagged graph instead of the manual one when
# searching (optional, default: no).
ckan.dataontosearch.use_autotag = yes
------------------------
Development Installation
------------------------
To install ckanext-dataontosearch for development, activate your CKAN virtualenv and
do::
git clone https://github.com/tobinus/ckanext-dataontosearch.git
cd ckanext-dataontosearch
python setup.py develop
pip install -r dev-requirements.txt
-----------
Future Work
-----------
There are plenty of things that should be improved. Here are some of them:
- Integrate concept viewing/editing with the dataset type of view, so the tabs
don't disappear once you click on "Concepts".
- Some styling improvements can be done to make it look more appealing and be
easier to use.
- Give feedback to the user when they save concept changes successfully.
- Use progress indicator of some kind when the user submits concept changes, and
stop them from submitting more than once.
- Give the user an idea of how the concepts relate to one another in a hierarchy,
instead of just a flat list. They should only use the most relevant, specific
concepts, and not try to fit many "similar" concepts, like you would with tags
or search words.
- Give the user more context for each concept. There exist alternate labels that
sometimes indicate what other areas that concept is covering, and some even
have text that explain and show how to apply that concept. This would require
changes to the dataset_tagger API in DataOntoSearch to make the information
available to ckanext-dataontosearch.
- Separate the two different plugins into two different Python files, per the
CKAN recommendations (to avoid problems with files loading out of order).
- Add translations.
There are also some TODO notes in the source code.
-----------------
Running the Tests
-----------------
.. NOTE::
No tests have been written for this project yet.
To run the tests, do::
nosetests --nologcapture --with-pylons=test.ini
To run the tests and produce a coverage report, first make sure you have
coverage installed in your virtualenv (``pip install coverage``) then run::
nosetests --nologcapture --with-pylons=test.ini --with-coverage --cover-package=ckanext.dataontosearch --cover-inclusive --cover-erase --cover-tests
-------------------------------------------------
Releasing a New Version of ckanext-dataontosearch
-------------------------------------------------
.. NOTE::
Publishing on PyPi under the same name (ckanext-dataontosearch) is only
possible if you receive rights from one who already has access. You should be
able to make contact through an author's GitHub user.
ckanext-dataontosearch is availabe on PyPI as https://pypi.python.org/pypi/ckanext-dataontosearch.
To publish a new version to PyPI follow these steps:
1. Update the version number in the ``setup.py`` file.
See `PEP 440 <http://legacy.python.org/dev/peps/pep-0440/#public-version-identifiers>`_
for how to choose version numbers, using the principles of `semantic versioning <https://semver.org/>`_.
2. Create a source distribution of the new version::
python setup.py sdist
3. Upload the source distribution to PyPI (assuming you have run ``pip install twine`` before)::
twine upload dist/*
4. Tag the new release of the project on GitHub with the version number from
the ``setup.py`` file. For example if the version number in ``setup.py`` is
0.0.2 then do::
git tag 0.0.2
git push --tags
