Help:Namespace
Page titles in MediaWiki are composed of two parts: an optional namespace name, and the remainder of the title. For example, this page has the title [[Help:Namespace]], so it is in the Help namespace. A title without a colon, for example [[Goings-on]], is in the main namespace.
By default, a wiki using the MediaWiki software has 18 namespaces, including:
- the main namespace, where page names have no prefix
- 15 additional namespaces, each with its own prefix. (Two namespaces, the so-called 'project' namespaces, get their names from the name of the wiki project, and so differ in name from one wiki to the next; on the ISFDB, they are called ISFDB: and ISFDB talk:. On each wiki, these project namespaces (whatever they may happen to be for that wiki), can be referred to by the pseudonyms "Project:" and "Project Talk:", respectively.)
- two pseudo-namespaces
But take note:
- If a page title contains a colon, but the initial part of the title is not one of the pre-defined namespaces, that page is considered to be in the main namespace.
