An article on that list is said to be &#039;&#039;in&#039;&#039; the category. Each category has a page, called a &#039;&#039;category page&#039;&#039;, that provides the list along with general information about further resources on these pages (for instance, related categories).<br /> <br /> An article can be in multiple categories. The categories in which an article is, can be found in a box at the bottom of the article.<br /> <br /> ===Subject wikis convention: categories versus supercategories===<br /> <br /> The MediaWiki software powering subject wiki allows categories to be in categories, and calls a category inside another category a &#039;&#039;subcategory&#039;&#039;. We make use of subcategories in two ways.<br /> <br /> In addition to the categories described above, which are lists of articles, the subject wikis also have certain other categories, which are &#039;&#039;lists of categories&#039;&#039;. These are called &#039;&#039;supercategories&#039;&#039;. A supercategory &#039;&#039;only&#039;&#039; contains categories but does &#039;&#039;not&#039;&#039; contain any articles.<br /> <br /> Further, some ordinary categories in subject wikis have &#039;&#039;subcategories&#039;&#039;. For a subcategory of an ordinary category, the following convention is used: all articles in the subcategory are &#039;&#039;also&#039;&#039; in the main category.<br /> <br /> ===Use of categories===<br /> <br /> Categories are used for two purposes:<br /> <br /> * Indicating the &#039;&#039;type&#039;&#039; of a definition, fact, or other article.<br /> * Indicating the &#039;&#039;topic area&#039;&#039; of a definition, fact, or other article.<br /> * Indicating the &#039;&#039;difficulty level&#039;&#039; of a definition, fact, or other article.<br /> <br /> In other words, categories are used for clustering, either based on a logical notion of type, or based on other criteria.<br /> <br /> ===Categories versus semantic MediaWiki===<br /> <br /> Categories are &#039;&#039;not&#039;&#039; used for relationships between multiple terms, facts and survey articles &#039;&#039;except&#039;&#039; when such relationships give rise to a strong cluster around a center. Thus, there may be a category titled &#039;&#039;variations of normality&#039;&#039; if there is a cluster of many variations of normality. However, there is unlikely to be a category of &#039;&#039;things stronger than normality&#039;&#039; if the relation is more symmetric and does not lead to clustering behavior.<br /> <br /> For such relations, semantic MediaWiki is used. These allow relations with different tags between properties.<br /> <br /> {{further|[[Subwiki:Semantic MediaWiki]]}}</div>
