About

The Taxonomy module allows users who have permission to create and edit content to categorize (tag) content of that type. Users who have the Administer vocabularies and terms permission can add vocabularies that contain a set of related terms. The terms in a vocabulary can either be pre-set by an administrator or built gradually as content is added and edited. Terms may be organized hierarchically if desired.

For more information, see the online documentation for the Taxonomy module.

Uses

Managing vocabularies

Users who have the Administer vocabularies and terms permission can add and edit vocabularies from the Taxonomy administration page. Vocabularies can be deleted from their Edit vocabulary page. Users with the Taxonomy term: Administer fields permission may add additional fields for terms in that vocabulary using the Field UI module.

Managing terms

Users who have the Administer vocabularies and terms permission or the Edit terms permission for a particular vocabulary can add, edit, and organize the terms in a vocabulary from a vocabulary's term listing page, which can be accessed by going to the Taxonomy administration page and clicking List terms in the Operations column. Users must have the Administer vocabularies and terms permission or the Delete terms permission for a particular vocabulary to delete terms.

Classifying entity content

A user with the Administer fields permission for a certain entity type may add Taxonomy term reference fields to the entity type, which will allow entities to be classified using taxonomy terms. See the Entity Reference help for more information about reference fields. See the Field module help and the Field UI help pages for general information on fields and how to create and manage them.

Adding new terms during content creation

Allowing users to add new terms gradually builds a vocabulary as content is added and edited. Users can add new terms if either of the two Autocomplete widgets is chosen for the Taxonomy term reference field in the Manage form display page for the field. You will also need to enable the Create referenced entities if they don't already exist option, and restrict the field to one vocabulary.

Configuring displays and form displays

See the Entity Reference help page for the field widgets and formatters that can be configured for any reference field on the Manage display and Manage form display pages. Taxonomy additionally provides an RSS category formatter that displays nothing when the entity item is displayed as HTML, but displays an RSS category instead of a list when the entity item is displayed in an RSS feed.
