ckanext-composite

Allows to store structured dataset metadata, single or multiple fields. Only one level of subfields is possible. The subfields can be basic text, date type o choice dropboxes. Do not use dashes or numbers in the labels or values of fields.

Requirements

Supports currently CKAN 2.9. There is a legacy branch for CKAN 2.8 (https://github.com/EnviDat/ckanext-composite/tree/ckan-2.8). Requires the extensions ckanext-scheming and ckanext-repeating (using version from repository eawag-rdm).

Installation

To install ckanext-composite:

Install the ckan extensions ckanext-scheming and ckanext-composite
Activate your CKAN virtual environment, for example:
```
. /usr/lib/ckan/default/bin/activate
```
Install the ckanext-composite Python package into your virtual environment:
```
pip install ckanext-composite
```
Add composite to the ckan.plugins setting in your CKAN config file (by default the config file is located at /etc/ckan/default/production.ini).
Restart CKAN. For example if you've deployed CKAN with Apache on Ubuntu:
```
sudo service apache2 reload
```
