   pip install -r dev-requirements.txt

3. Add spc to the ckan.plugins setting in your CKAN config file (by default the config file is located at /etc/ckan/default/production.ini).
4. For the SpcNadaHarvester to work, install this branch of ckanext-ddi: github.com/roly97/ckanext-ddi/tree/nada_harvester. Alternatively, install the original ckanext-ddi extension github.com/liip/ckanext-ddi and then replace the files ddiharvester.py and metadata.py with the changed files found in ckanext-ddi_changes directory in this repo.

   <field name="topic" type="string" indexed="true" stored="true" multiValued="true"/>

6. Update DB schema:

   paster spc db-upgrade -c config.ini

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

   sudo service apache2 reload

Config options:

scheming.dataset_schemas = ckanext.spc.schemas:dataset.json

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

git clone https://github.com/DataShades/ckanext-spc.git
cd ckanext-spc
python setup.py develop
pip install -r dev-requirements.txt
paster spc db-upgrade -c config.ini

This extension provides new template macro _nested_field which is used for rendering fields in nested schemas. It can be easily added to any page that have access to dataset metadata via next snippet:

{{ nested_field(parent_field_name, index_of_current_field_amoung_other_siblings, current_field_name, parent_data_dict, parent_errors_dict) }}

More examples can be found in templates/macro/spc.html.
