Managing taxonomy
In Chapter 3, Basic Concepts, we briefly discussed Drupal's Taxonomy feature.
In Chapter 4, Getting Started with the UI, you created Article nodes tagged with the terms: tag1, tag2, tag3, and tag4, and in Chapter 5, Basic Content, you created more Article nodes tagged with the terms pet and dog.
The Tags vocabulary is a tag-based vocabulary, which means that content editors can make up as many terms (words or phrases) as they like and will be prompted to re-use any existing terms as they type. Tag-based vocabularies are great when you need your content-editing team to use their expert subject knowledge to build up a collection of terms, but the downside of them is that the collections can fill up with duplication owing to misspellings.
Note
Taxonomy vocabularies based on a fixed set of terms are often more useful. What we will do next is set up a fixed vocabulary to help us to categorize all the content (pages, services, clients, and news) across the site.
