ckanext-relationships

This extension provides functional changes to the way relationships in CKAN work.

Core CKAN restrictions for creating relationships:

• Must always contain a subject package and object package
• User must have package_update permission on both subject and object packages

External Relationships

In some CKAN instances it may be a requirement to create relationships to external URIs.

This extension enables this by allowing the object_package_id to be empty and uses the comment to store the external URI.

Relax package_relationship_create permissions

In some CKAN instances it may be a requirement to allow users to create relationships from a package they DO have package_update permission for TO a package they DON'T have package_update permission for, i.e. creating a relationship between a package in an org they are an admin/editor in, to a package in another org that they are not and admin/editor in.

Config

This extension checks for the following setting in the CKAN .ini file:

ckanext.relationships.package_relationship_create_ignore_auth_for

This should be set to a space separated list of user roles to allow, e.g.

ckanext.relationships.package_relationship_create_ignore_auth_for = admin editor
