There are many namespaces in Wikidata; this page provides information on some of the key ones you might encounter as a contributor. For a full list, see the advanced search option at Special:Search which allows you to search Wikidata by namespace.

List of namespaces[edit]

Main namespace[edit]

The main namespace is reserved for items only. Instead of following the convention of a name followed by a colon, for the URL of pages in this namespace, page titles immediately follow the forward slash after the word 'wiki'. Pages are titled according to their unique identifiers (Q###). They don't contain wiki code and their content is internally formatted in JSON.

Example page:


This namespace is only for properties. It is similar to the main namespace in that it is for editing data. Pages are also titled according to unique identifiers—in this case, P###. For pages in the main and property namespaces, it is only possible to edit the respective parts of an item or a property through the various edit links. There is no main "edit" tab at the top right side of item or property pages and the pages contain no wiki code, like the main-space pages. For more information on editing items and properties, see Help:Items and Help:Properties.

Example page:


The Wikidata namespace, or project namespace, is for pages with information or discussion about Wikidata itself, such as status updates by the development team. This is also where you can find task forces, groups of contributors who work together to improve a particular aspect of Wikidata.

Example page:


This namespace is used for user pages. Each Wikidata user has a corresponding page in the User namespace, which is linked to from edit histories and wherever an individual user is uniquely identified.

Example page:

Talk namespaces[edit]

Talk namespaces exist for all of the above namespaces; a talk namespace is used for discussions related to its corresponding namespace. For example, the Help Talk namespace could be used for giving or receiving feedback on proposed changes to Help pages; the Property Talk namespace is where debate and discussion of a specific property and its appropriate usage takes place.

Example pages:


This namespace is used for special pages that are used for administrative purposes, like statistics, maintenance reports, and user accounts and permissions. The pages are not directly editable and it is not possible to create pages in this namespace except by modifying the MediaWiki software.

Example page:

Yellow background color indicates data namespaces, while the others are meta namespaces available on the Wikidata server.
