2 Namespaces

2.1. What is a namespace?

A namespace defines an area in your knowledge base. You can recognize a namespace by the namespace prefix in the page title:

<namespace>:Page title

In your knowledge base, you will find predefined namespaces. In addition, administrators can create custom namespaces as needed. There are certain aspects of namespaces that are important to consider before creating a namespace. It is therefore important to understand the characteristics of namespaces and the reasons for using a custom namespace.

You can create your own namespaces to separate articles (e.g., Meeting minutes, Work instructions, Processes) from other types of content, or to separate articles by department.

2.1.1. Characteristics of a namespace

  • Activation of features: Different functions can be activated in each namespace (e.g., page approvals or read confirmations).
  • Search function: Search can be limited to individual namespaces (namespace filter).
  • One namespace per page: The same page name in a different namespace creates a new page.
  • Flat structure: Namespaces cannot contain other namespaces.
  • File associations: Uploaded files can be assigned to a namespace.

2.2. Standard namespaces

The system uses, among others, the 15 standard and the two so-called pseudo namespaces from MediaWiki base:

ID Namespace Function
Media Pseudo-namespace for uploaded images and files. Will be replaced by path of the files.
special Pseudo-namespace for special pages.
0 (pages) These are given without a prefix.
1 Talk talk page. Is created in addition to each article (also in the following namespaces) to speak about its contents. Additional tab (+).
2 User User page. Will be created for every logged in user.
3 User talk Cf. talk
4 [knowledge base-Name] Information about the knowledge base or the current project.
5 [knowledge base-Name]_Talk Cf. talk
6 Image Description of a picture and other files. Is automatically supplemented with version information and information about the occurrence of the file
7 File_Talk Cf. talk
8 MediaWiki base system messages. A complete list can be found under Special: AllMessages. Can only be changed by registered users.
9 MediaWiki base_Talk Cf. talk
10 Template Templates can be integrated into other pages.
11 Template_talk Cf. talk
12 Help Help pages describe how to perform actions in the knowledge base. No clear separation from the [knowledge base name] namespace.
13 Help_talk Cf. talk
14 Category Pages can be assigned to categories, which are then accessible in this namespace.
15 Category_talk Cf. talk

Standard namespace: A page is assigned to the "Main" namespace, as long as no other namespace is specified.

Pseudo namespaces: The two pseudo namespaces (Media, Special) are used like normal namespaces, but you cannot edit them or add pages to them.

Most pages in the namespaces are created automatically:

  • Special pages are generated by the system during installation.
  • Media and image pages are created during file uplad.
  • User pages are created whenever a user acts on the knowledge base.
  • Discussion pages are also created with the corresponding pages.

This leaves only the default namespaces (Main), [knowledge base name], Template, Help and Category namespaces where pages can be freely created.

2.3. Creating a new namespace

You can create additional namespaces. Go to Global actions > Management > Namespaces.

2.4. Accessing pages in a namespace

To access or create a page in a specific namespace, its name is simply placed in front of the page title and separated by a colon:


In the example, the pipe symbol (straight line) was also added. It has the effect that the namespace won't be displayed for the link label.

If you provide a namespace that is not known to the knowledge base, the page is created in the standard namespace Main. The portion of the reference specified as the namespace is then added to the title of the item instead and is not recognized as a namespace label.

2.5. Viewing all pages of a namespace

You can view all pages in a namespace:

  1. Go to the Special page "All Pages".
  2. Leave the input field empty.
  3. Select a namespace from the Namespace drop-down menu. Newly added namespaces will appear at the bottom of the list.
  4. Click Go.
