Taxonomy and Vocabulary

Definitions

A taxonomy in Drupal (and GovCMS) is a way to classify or categorise certain types of content.

A vocabulary is a group of taxonomy terms. A vocabulary can only be used to categorise one type of content. For example, only the Event categories vocabulary can be used to categorise content of type Event.

These terms and the distinction between them is best illustrated by an example. Page articles can be classified or categorised by the Topics they relate to. The categories or taxonomy terms can be Policies, News or Services. The vocabulary in this example would be called Topics.
