The ckanext-multilang CKAN's extension provides a way to localize your CKAN's title and description contents for: Dataset, Resources, Tags, Organizations and Groups. This extension creates some new DB tables for this purpose containing localized contents in base of the configured CKAN's locales in configuration (the production.ini file). So, accessing the CKAN's GUI in 'en', for example, the User can create a new Dataset and automatically new localized records for that language will be created in the multilang tables. In the same way, changing the GUI's language, from the CKAN's language dropdown, the user will be able to edit again the same Dataset in order to specify 'title' and 'description' of the Dataset for the new selected language. In this way Dataset's title and description will automatically change simply switching the language from the CKAN's dropdonw.

The ckanext-multilang provides also an harvester built on top of the ckanext-spatial extension, and inherits all of its functionalities. With this harvester, localized content for Dataset in CKAN can be retrieved form CSW metadata that contains the gmd:PT_FreeText XML element (see the WIKI for more details).

The WIKI page of this CKAN extension can be found here <https://github.com/geosolutions-it/ckanext-multilang/wiki>_ in this repository.

The ckanext-multilang extension has been developed for CKAN 2.4 or later. In addition:

• The CSW multilingual harvester provided by the ckanext-multilang extension requires the ckanext-spatial plugin installed on CKAN (see the WIKI for more details about that).

• The CSW multilingual harvester provided by the ckanext-multilang extension requires the ckanext-geonetwork plugin installed on CKAN if you want to leverage on the advanced harvesting functionalities (see the WIKI for more details about the multilang harvester).

To install ckanext-multilang:

1. Activate your CKAN virtual environment, for example:

   . /usr/lib/ckan/default/bin/activate

2. Go into your CKAN path for extension (like /usr/lib/ckan/default/src):

   git clone https://github.com/geosolutions-it/ckanext-multilang.git

   cd ckanext-multilang

   pip install -e .

3. Initialize the DB with the mandatory Tables needed for localized records:

   paster --plugin=ckanext-multilang multilangdb initdb --config=/etc/ckan/default/production.ini

4. Add multilang and multilang_harvester to the ckan.plugins setting in your CKAN config file (by default the config file is located at /etc/ckan/default/production.ini).

5. If you need different resources bound to different languages, add the multilang_resources plugin. See also the related wiki page.

6. Update the Solr schema.xml file used by CKAN introducing the following elements.

   Inside the 'fields' Tag:

      <dynamicField name="package_multilang_localized_*" type="text" indexed="true" stored="true" multiValued="false"/>
   

   A new 'copyField' to append:

      <copyField source="package_multilang_localized_*" dest="text"/>
   

7. Restart Solr.

8. Restart CKAN. For example if you've deployed CKAN with Apache on Ubuntu:

   sudo service apache2 reload

To install ckanext-multilang for development, activate your CKAN virtualenv and do:

git clone https://github.com/geosolutions-it/ckanext-multilang.git

cd ckanext-multilang

python setup.py develop

pip install -r dev-requirements.txt
