Under the toolbar option Structure, Taxonomy is a list of all the vocabularies on your website. In a standard Drupal installation you will only see tags. (See figure 7.2) Each vocabulary is presented along with some management links for editing the vocabulary settings, listing existing terms, and adding new terms.


Figure 7.2: The administration page for taxonomy has links to manage each vocabulary, and create new ones.

The list of taxonomy terms allows you as administrator to reorder the terms, which includes creating tree structures. It is also possible to edit each term (See figure 7.3) The form for adding or editing terms holds information about the term name, any URL alias for the term, and also a term description. (See figure 7.4) The term description is actually an entity field, and it is possible to add more fields to terms. The edit page also allows you to set any parent terms, but this is easier to manage in the drag-and-drop list of terms.


Figure 7.3: Each vocabulary has a list of all its terms. Terms can be sorted into a tree structure.


Figure 7.4: Each term may be edited. You can change the fields available on terms, for example adding images to terms.

TIP: It is possible to select more than one parent term on the term edit page. This allows for interesting relations between terms, but makes it impossible to use the click-and-drag list for managing the list of terms. If you set more than one parent term, the click-and-drag list is disabled.

Above the list of vocabularies you will find a link add vocabulary, leading to a form used for (you guessed it) adding new vocabularies. Each vocabulary has a name and, optionally, a description. Drupal will automatically suggest a machine name for the vocabulary, based on its plain-text name.
