ckanext-taxonomy

The current support for tag vocabularies in CKAN is rather limited, and this extension provides an alternative implementation of tags, or more accurately terms where:

• Terms belong to a taxonomy which is a simple named entity
• Terms can have child terms and parent terms so that they are hierarchichal.
• Terms have a name, but also a URI, and a title which is the display string
• Terms and taxonomies can be generated from SKOS data.

Information about the API is available in API.md

Installation

To install ckanext-taxonomy, you should follow these steps:

1. Install the code

   cd /usr/lib/ckan/default/src
   git clone https://github.com/datagovuk/ckanext-taxonomy.git
   cd ckanext-taxonomy
   python setup.py install
   

   NB you should not use pip install -e to install it, since that appears to install the copy of python-skos from PyPI when it should install the DGU version. If you get this wrong then you get erro TypeError: init() got an unexpected keyword argument 'lang'

2. Add taxonomy to your ckan.plugins setting in your ckan.ini file

3. Setup the database for taxonomies

   paster taxonomy init -c <PATH-TO-CONFIG>
   

Running tests

cd ckanext-taxonomy
nosetests . --with-pylons=test-core.ini

Importing a SKOS document

WARNING: Importing will currently delete an existing taxonomy if it exists with the same name. If you are using term uris in your schema this shouldn’t be a problem if you are copying the same taxonomy over the top.
