Editing MycoTaxa:Namespace (section)

== Namespace-dependent functionality ==
The namespace name is a useful variable for searching in and reporting on sets of [[WP:Page name|pages]]. It is also used to apply features that configure the sets of pages in one namespace differently from another namespace. Using the namespace name MediaWiki can:
*[[WP:Search|Search]] for pages in a particular namespace only.
* [[Help:Special page|Report]] on [[Special:AllPages|content]] or [[WP:Recent changes|changes in content]] of a namespace.
* Enable or disable the [[WP:Subpage|subpage]] feature, per namespace.
* Offer a [[WP:Random article|random article]] for the mainspace (<kbd><nowiki>[[</nowiki>Special:Random<nowiki>]]</nowiki></kbd>), or for a namespace <kbd><nowiki>[[</nowiki>Special:Random/''Namespace'']]</kbd>.
* Change the functionality of <kbd><nowiki>[[</nowiki>''wikilink''<nowiki>]]</nowiki></kbd> if it targets the '''Category''' namespace or '''File''' namespace. Normally wikilinks are activated by the mouse, but <kbd><nowiki>[[</nowiki>Category:''Pagename''<nowiki>]]</nowiki></kbd> activates software functionality when the [[WP:Category|page is saved]], and <kbd><nowiki>[[</nowiki>File:''Page name''<nowiki>]]</nowiki></kbd> activates software functionality when the [[WP:Image|page is rendered]].
* Change the functionality of <kbd><nowiki>{{</nowiki>[[WP:Transclusion|pagename]]<nowiki>}}</nowiki></kbd> so that it defaults to the set of pagenames in '''Template'''.
* Tailor ''[[Wikipedia:Edit notices|edit notices]]'' to a particular namespace's edit page, informing an editor of certain aspects about the content of that namespace.
* Allow ''[[Wikipedia:Templates|templates]]'' to behave differently on pages of different namespaces.

The namespace functionality is often visible in the URL, where you will see a namespace number. These are given in the table below.

Subpages are configured for all namespaces except Main, File, MediaWiki and Category namespaces. Subpages are configured in the software by enabling or disabling the subpage feature per namespace. This further extends the function of a namespace by extending the types of pages or topics of pages a namespace can home. For example, talk page ''/archives'' are subpages, and they are both namespace searchable and page name searchable from the search box, unlike [[WP:page history|history pages]], which are in no namespace. Another example is in the Template namespace where it is routine to put the documentation in a subpage called ''/doc''.

Random pages are enabled, in the default software configuration, only for the mainspace.

Searching and reporting can operate over the entire database, or they can be limited to a namespace, and so they will offer a list of all the namespaces currently configured. [[Special:WhatLinksHere]] also offers a list of namespaces.
