Categories allow articles to be placed in one or more groups, and allow those groups to be further categorized. When an article belongs to a category, it will contain a special link to a page that describes the category. Similarly, when a sub-category belongs to a parent category, it will contain a special link to the parent category's page. | |||

Each category page contains an introduction that can be edited like an article, and an automatically generated list of links to sub-categories and articles that belong to the category. | Each category page contains an introduction that can be edited like an article, and an automatically generated list of links to sub-categories and articles that belong to the category. | ||
Categories do not form a strict hierarchy or tree of categories, since each article can appear in more than one category, and each category can appear in more than one parent category. This allows multiple categorization schemes to co-exist simultaneously. It is possible to construct loops in the category space, but this is discouraged. | Categories do not form a strict hierarchy or tree of categories, since each article can appear in more than one category, and each category can appear in more than one parent category.

It is expected that most pages will be members of more than one category. Similarly, each category can be a member of more than one parent category. | |||
== | ==Categories vs. Lists== | ||
Grouping articles into a category is not the same as making a list of articles. To make a list of articles, you edit the list directly; but to place articles into a category, you edit each article and insert a category tag by placing <nowiki>[[Category:</nowiki>''category_name''<nowiki>]]</nowiki> in the body of the text. This automatically adds those articles as a list on the category's page. Despite the difference in how they are maintained, it is sometimes convenient to think of a category as a list of articles. | Grouping articles into a category is not the same as making a list of articles.

While an article may be in multiple lists, the goal is that browsing downwards from a list parent category, e.g. [[:Category:People]], should only arrive at articles that are about people, e.g. [[John Lennon]], and not related articles e.g. [[251 Menlove Avenue]]. | While an article may be in multiple lists, the goal is that browsing downwards from a list parent category, e.g. [[Wikipedia:Category:People|Category:People]], should only arrive at articles that are about people, e.g. [[Wikipedia:John Lennon|John Lennon]], and not related articles e.g. [[Wikipedia:251 Menlove Avenue|251 Menlove Avenue]]. | ||

=== | ==Maintenance Categories== | ||
Some categories exist to aid maintenance of the UniWiki, for example, [[Wikipedia:Wikipedia:template|template]] categories and [[Wikipedia:Wikipedia:redirect|redirect]] categories. Maintenance categories are often added by templates, {{code|<nowiki>{{...}}</nowiki>}} rather than by the "wikilink" structure, {{code|<nowiki>[[...]]</nowiki>}}. Benefits of template usage include the ability to populate more than one category with a single template, inclusion of text to explain the rationale of a given categorization(s), the ability to readily include/exclude certain pages or types of pages, and so on. Contributors may monitor these maintenance categories for many reasons to include compliance with policies and guidelines that pertain to various conventions, such as page [[Wikipedia:naming convention|naming convention]]s. | |||
