CKAN provides several key features that allow users of a CKAN portal to communicate and collaborate on data.

Comments extension – users can add comments and discussion on a dataset. The extension can be enabled or disabled at any time.

Share – users can quickly and easily promote and discuss a dataset using twitter and facebook integration.

RSS/Atom feeds – create feeds of any changes and revisions to datasets and groups.

Follow extension – ‘follow’ a dataset to be informed of any changes, updates or new activity.

To do extension – flag a dataset with an issue or instructions of what is missing or still ‘to do’. This allows for a community driven effort for improving and adding to metadata.
