Beginning Drupal 8

Chapter 4 ■ Taxonomy
approach is to think about the content that you will include and the subjects that the content will cover.
If the subjects are all related (for example, types of sports), then a single vocabulary is likely all that you will
need. If the subjects are not related (for example, a book-related website where books may be categorized by
author, subject, publisher, and targeted audience), then the use of several vocabularies may be necessary.
It’s up to you, the site creator, to define the structure that best suits the purpose of your site, how you want
content structured, and how you want visitors to access that content.
Once you’ve identified at least one vocabulary, click the Manage link in the admin menu at the top
of any page on your site and then click the Structure link. You’ll see a list of options that includes a link to
Taxonomy. Click that to reveal a page that lists all of the vocabularies that have already been defined for
your site. By default, Drupal creates a vocabulary called Tags as a default generic “container” for terms.
See Figure 4-1.
Figure 4-1. The Tags vocabulary
To add a new vocabulary, click the “Add vocabulary” link at the top of the list, revealing the form shown
in Figure 4-2. In the Name field, enter “Type of Sport,” and enter a brief description in the Description field.
The Description field is an optional field and by default is not displayed on the administrative interface for
taxonomy. However, you may want to use this field when rendering lists of content as a description about the
content that is contained in the list.
Figure 4-2. Creating a new vocabulary
Once you’ve entered values in both fields, click Save. Drupal then displays the list of terms associated
with your vocabulary. Since this is a new vocabulary, the list is empty. See Figure 4-3.
