How to add taxonomy (tagging) to content in Open Atrium

Global Vocabularies

You do this the same way you normally do in Drupal. Create Taxonomies and then add taxonomy reference fields to the content types. See the Drupal 7 documentation on taxonomies for more information.

Space-Specific Vocabularies

Atrium supports space-specific vocabularies/taxonomies if you don't need one that is global to the site and with the space-specific taxonomies there is an easy interface for adding them to different content types rather than creating your own fields and adding them via the Drupal field UI. Go to the Space and then select Config in the gear-icon menu and go to Taxonomy to create space-level taxonomies.

You can then use those taxonomies in the Files/Folder widget to organize your documents. We've even seen clients use more than one File/Folder widget with more than one taxonomy to show different "views" of their documents on the same page.

Shared Vocabularies

Space-level taxonomies can also be shared across different spaces. You will need to enable this feature by going to Admin > Configuration > Organic Groups > OG Vocabulary Settings. On that page, enable "Allow groups to share vocabularies". Then, when adding or editing a new space-specific taxonomy, you will now see a "Shared Vocabulary" option. Click that check-box. Now, when you want to add this shared vocabulary to another space, you follow the same path (config > taxonomy) and you'll see a list of existing taxonomies you can choose to add to your space.
