CHAPTER 2 CONFIGURING DRUPAL Using Categories One (Linux web host)
CHAPTER 2 CONFIGURING DRUPAL Using Categories One of Drupal s hottest features is its outstanding support for classification of content through the application of categories. Categories are sometimes referred to as taxonomies, a slightly more technical term that means basically the same thing. You need to have the Taxonomy module enabled in order to use categories. Note Categories require the Taxonomy module to be enabled. Understanding Vocabularies and Terms Drupal divides the task of categorization into two general concepts: vocabularies and terms. A vocabulary represents a general concept and is collection of words or phrases that are all dif ferent ways of describing the same thing. A term is a word or phrase providing a concrete example of the vocabulary s general concept. For example, if Animals were a vocabulary, dog, bird, fish, and cow would all be terms in it. If you were trying to categorize the news, you might use terms like International, State, and Local to describe the different types of news. In Drupal, that structure would be represented with a vocabulary News that has three terms: News International State Local Vocabularies can be assigned to different content types. This allows you to categorize every post of that type using the terms in the vocabulary. If you were to assign the News vocabulary to story types, every time you created a new story, you would have the choice of categorizing it as International, State, or Local. When the content is viewed, Drupal displays category links indicating how the content has been categorized and leading to pages that show other content in the same category. These features alone make categories a great tool for organizing the content on your web site. They allow visitors to get to all of the posts that have been made within a certain category and give content creators an opportunity to classify the content they are creating. The category system is capable of much more, however. The hierarchy of a vocabulary is not limited to a simple list of terms. For example, you could expand the International term of the News taxonomy to have subcategories as well: News International Politics Business Travel Here, the International term has three subterms: Politics, Business, and Travel. In this case, those three terms have International as a parent. If each term can have only one parent,
