Handbuch:Kategorien
Categories in MediaWiki are used to group similar pages, and groups of similar groups, together to form one or more tree-like hierarchies.
Datenbank
MediaWiki keeps category data in the category and categorylinks tables.
API
Several API modules provide access to category information: API:Kategorien, API:Kategorie-Info, API:Alle Kategorien, API:Kategorienmitglieder
Benutzeroberfläche
- Special:Categories - lists all categories which have at least one page.

A number of category extensions are available; one of the more popular ones, CategoryTree, provides a dynamic view of the wiki's category structure as a tree.
