The MediaWiki software powering Memory Beta provides fifteen namespaces. A namespace is a "zone" that contains specific types of wiki content.

Regular namespacesEdit

  • The main namespace is the zone for the actual encyclopedia of Memory Beta. It contains no prefix, and pages in this namespace are created simply by creating [[links]].
  • The Memory Beta: namespace is the namespace for pages pertaining to the project. These pages might sometimes be referred to as "meta" pages.
  • The User: namespace is set aside for personalized pages pertaining to the Memory Beta contributors. This may include personal presentations, scratch pages, rough drafts, and archives of content. It is not intended for use as personal webspace.
  • The Forum: namespace contains discussion pages, such as those in Ten Forward.
  • The Help: namespace is for pages that provide guidance for using the MediaWiki software.
  • The Image: namespace is created for image description pages that provide information concerning images. (This also applies to other kinds of media, such as sounds and movies.)
  • The Special: namespace is a namespace consisting solely of pages that are created by the MediaWiki software on demand (i.e. recent changes). These pages can be linked using the usual method, except when parameters are required (then the full URL must be used).
  • The Template: namespace is used to create customizable sections of text that can be included in multiple articles. The are included using the {{template}} markup (see Templates).
  • The MediaWiki: namespace is used to contain text clippings that allow customization of the wiki's user interface. Pages in this namespace may only be edited by the administrators.
  • The Category: namespace contains all the various categories into which articles can be grouped.

Talk namespacesEdit

Each namespace (except for Special:) also has an associated Talk: namespace linked to it. These pages are set aside for discussion of the articles as necessary. Examples of the most frequently used Talk namespaces are:

  • Talk:
  • User talk:
  • Image talk:

A namespace is a way of separating types of content on a wiki; groups of pages with similar purposes can be grouped together, and can be searched and listed separately from each other. Each page belongs to exactly one namespace.

The namespace of a page is indicated by the word preceding the colon in the page title. For example, "Talk:Pagename" is a page in the "talk" namespace, and is used to describe a page called pagename. If there is no prefix (or the prefix does not match an existing namespace) the page belongs to the "Main" or "article" namespace of that wiki.

Custom namespaces can be created on a wiki if the standard ones do not meet the needs of that community's project.

Namespaces are used for the following reasons:

  • Allow separation of wiki content from help and policy pages about the creation of content;
  • Allow separation of different kinds of unrelated content;
  • Allow control of which content is indexed by search engines;
  • Provide some special features related to the namespace's intended purpose;
  • Provide facilities to limit searches to a particular area;
  • Allow easy exporting.

What namespaces do all communities have?

By default, every wiki has 18 namespaces, and 2 special namespaces. Custom namespaces can also be created.

Namespace Code Namespace Name Notes
{{ns:-2}} Media

An API query can be used to list all namespaces on a community, including custom namespaces. To do so, replace 'NAME' in the following URL with your community's:


For example, Community Central's list.

What are the basic namespaces?


You can see a list of all the namespaces on your wiki by going to Special:AllPages and clicking the dropdown menu next to "Namespace"

The Main or article namespace ({{ns:0}}) is the informational content of the wiki. In Wikipedia, this would be an encyclopedia article. It is the default namespace and does not use a prefix. Only the Main namespace is indexed by public search engines such as Google or Bing.

The Project namespace's prefix is the title of your wiki (the same title displayed in the {{SITENAME}} variable). On some wikis, this namespace is used for policies and guidelines, deletion discussions, requests for administratorship, and other behind-the-scenes details; other wikis use it for other purposes, or don't use it at all. If you don't know the name of the wiki (or just don't want to bother to type it,) you can use the shortcut, "Project:" as a substitute. This will be converted automatically to the real name of the wiki. For example, on the Community Central wiki, Project:Admins will link to the same page that Community Central:Admins does.

The User namespace has the prefix User: and is used for information about users of the wiki. A user has a main user page and possibly some sub-pages. The main user page is linked from page histories and from recent changes. A user page has links to a user's talk page and contributions.

The File namespace is prefixed with File:. Pages in this namespace are also called image description pages. They are used for information about images or other files. Every image uploaded will show the information given in the upload summary on the image description page. (note: the previous prefix Image: will continue to work)

The MediaWiki namespace (prefix MediaWiki:) contains behind-the-scenes code and messages such as link labels and color schemes. These are only editable by a wiki's administrators. An automatically generated list of all interface messages can be found at Special:Allmessages. See Help:System messages for more.

The Template namespace can be used for small standard texts which need to be inserted on a number of pages. Templates can be things like infoboxes or items in a list. They can be inserted with {{Template name}}; see Help:Templates for a more in-depth description.

The Category namespace contains categories of pages, with each displaying a list of pages in that category and optional additional text; see Help:Category.

The Help namespace is for help pages. The Shared Help system automatically provides pages from Fandom Help to each individual wiki, but projects can add their own notes about local practices above the shared text, and add new help pages that are unique to their projects in this namespace.

The Forum namespace can be used for threaded forum messages. These are normally conversations and questions for the entire wiki to contribute in. See Help:Wiki-style forums. Note: It is suggested to now use the Forum tool or Discussions instead.

What are the talk namespaces?

Except for special pages, each namespace has an associated talk namespace. The talk namespaces are designated by adding talk: to the normal prefix. For example, the talk namespace associated with the unprefixed main article namespace has the prefix Talk:, while the talk namespace associated with the User: namespace has the prefix User talk:. Most of the pages in the talk namespaces are used to discuss changes to the corresponding page in the associated namespace.

Pages in the user talk namespace are useful for leaving messages for a particular user, since they will get automatic notification of any messages left there; see Help:User page.

What are virtual namespaces?

There are two virtual namespaces that do not relate to pages stored in the database.

Special pages, or the special namespace, are automatically generated and uneditable pages, such as Special:RecentChanges or Special:UserLogin. They're vital to the MediaWiki software.

The Media prefix can be used to link directly to an image or sound clip, in the form [[Media:Image.jpg]] or [[Media:Sound.ogg]], rather than linking to the image description page.
