Manual:Espaço nominal

This page is a translated version of the page Manual:Namespace and the translation is 45% complete.

A namespace is a collection of pages which have content with a similar purpose, i.e. pages where the intended use is the same. Namespaces can be thought of as partitions of different types of information within the same wiki, and keep "real" content separate from user profiles, help pages, etc. The namespace prefix of a page forms part of the title of a page, separated with a colon (:).

Resumo técnico

As said, pages exist within a namespace, and this can be distinguished using the namespace prefix of a page, which forms part of the title of a page, separated with a colon (:).

Por exemplo:

Título Espaço de nomes Código
Foo Main 0
Template:Foo Template 10
Module:Foo Module 828

The "main namespace" does not have a prefix. Also, pages in the main namespace cannot have names starting with any of the existing namespaces prefixes followed by a colon.

Pages can be moved between namespaces simply by changing the prefix part of their title.

Namespace prefixes can be translated, and aliases can be configured for each (see $wgNamespaceAliases ). All namespaces also have a "canonical" prefix, which works on all wikis regardless of configuration. Aliases and canonical names can be used in links, when performing a search, and in the page title with the help of the {{DISPLAYTITLE}} magic word.

Each namespace has a corresponding namespace index. Within the database, the title is split into namespace index and text title, and this is used for storage in the page.page_namespace and page.page_title columns, among others.

Assunto e discussão de espaços nominais

See Ajuda:Páginas de Discussão for instructions on how to use talk pages.

Most namespaces have an associated discussion namespace (or "talk" namespace). All discussion namespaces have odd-integer indices, and the discussion namespace index for a specific namespace with index n is n+1. The namespaces with even-integer indices are subject namespaces (note that this is a distinct concept from content namespaces). The subject-talk duality can be explored using the {{SUBJECTPAGENAME}} and {{TALKPAGENAME}} magic words. The ‎<body> tag of pages in talk namespaces has the "ns-talk" CSS class, which might be useful for styling.

MediaWiki ships with 18 built-in namespaces:

  • 16 "real" namespaces, corresponding to actual pages, numbered 0 to 15, and grouped in subject/talk pairs
  • 2 "virtual" namespaces (one for dynamically generated special pages, and one serving as an alias for direct file links), numbered -1 and -2, respectively. Since these namespaces don't correspond to pages stored in the database, one cannot create or delete pages in these namespaces, and there are no corresponding discussion namespaces.

A lista completa é apresentada na tabela abaixo.

Índice Nome Objetivo Discussão
0 (Main) Artigos de conteúdo "Reais" .[1] Talk 1
2 User Páginas do utilizador .[2] User talk 3
4 Project Informação sobre a wiki.[3] Project talk 5
6 File Páginas de descrição de multimédia File talk 7
8 MediaWiki Personalização da interface do site[4] MediaWiki talk 9
10 Template Páginas de modelos Template talk 11
12 Help Páginas de ajuda Help talk 13
14 Category Páginas de descrição de categoria Category talk 15
-1 Special Holds special pages N/A
-2 Media Alias for direct links to media files

Each namespace also has a constant derived from its name, with all letters in uppercase, spaces replaced by underscores, and prefixed by "NS_". For example, the constant for the "User talk" namespace is NS_USER_TALK. A complete list can be found in Manual:Namespace constants .

  1. O espaço nominal do assunto não tem prefixo.
  2. Editing a User talk page generates a notification for the user.
  3. Defined by $wgMetaNamespace , which unless manually set otherwise, defaults to $wgSitename .
  4. Only editable by users with the 'editinterface' permission.
    Some few pages in this namespace require editsitecss and editesitejs permissions, in addition to that.

Espaços nominais personalizados

Extensions and site administrators can define additional namespaces to group additional classes of pages together. For a thorough overview, see Manual:Utilização dos espaços nominais personalizados .


Some namespaces, like Project and Help, only exist for convenience and do not have any extra functionality compared to the Main namespace.

Template namespace pages can be transcluded without namespace prefix.

User namespace pages are associated with user accounts or IP addresses. Changes to user talk pages generate an automatic message notification.

Pages in the "MediaWiki" namespace are used to override default messages in language file and can only be edited by administrators or other users with the editinterface permission.

File and Category pages have special functionality, as described in Help:Gestão de ficheiros and Ajuda:Categorias . Files can be moved by users with the "movefile" right. Category pages can be moved by users with the "move-categorypages" right.

All pages in discussion namespaces have a "post a comment" feature (see Help:Section#Adding a section at the end on Meta).
