Current development on JAMWiki is primarily focused on maintenance rather than new features due to a lack of developer availability. If you are interested in working on JAMWiki please join the jamwiki-devel mailing list.

Help:Namespaces

ktip.png This documentation of JAMWiki functionality is based on Mediawiki's reference at mediawiki:Help:Namespaces. Original content licensed in the public domain.

Pages on a JAMWiki wiki are grouped into collections called "namespaces", which differentiate between the purpose of the pages at a high level. Pages in certain namespaces can also have special properties or behave differently when they interact with other pages.

Namespaces are indicated in page titles by prefixing the page name with "namespace:", so the prefix "Help:" in this page's title ("Help:Namespaces") indicates that this page is in the Help namespace. Note, however, that colons and prefixes can also appear in page titles without indicating a namespace: The page Foo:Namespaces is a page located in the mainspace because the namespace "Foo" does not exist. Similarly the page Help:Foo:Namespaces is in the "Help" namespace.

As of version 0.9.0 JAMWiki uses the same default namespaces and namespace IDs as Mediawiki.

Contents

Standard namespaces[edit]

The standard JAMWiki installation has sixteen namespaces which can contain user-generated content; there are also two special namespaces which contain pages created 'on the fly' by the JAMWiki software. The standard namespaces are organised in pairs, with each pair containing a 'subject namespace' and a 'discussion namespace'. The namespaces are numbered from zero such that all subject namespaces have even indices, and all comments namespaces have odd indices.

-2: Media[edit]

This namespace is currently unused in JAMWiki.

-1: Special[edit]

This namespace is used to group special pages, reports and interfaces that are generated 'on demand' by JAMWiki and which are not directly editable. It is not possible to create pages in this namespace except by modifying or extending the JAMWiki software.

0: (Main)[edit]

Namespace zero is the 'null' namespace, commonly called the "main namespace" or "mainspace". This namespace typically contains the bulk of the content pages in a wiki. This namespace generally has no special properties.

1: Comments[edit]

The "Comments" namespace is the discussion namespace attached to the mainspace. It has no special properties.

2: User[edit]

Each user has a corresponding page in the User namespace, which is linked to from edit histories, watchlists, recent changes, etc; wherever an individual user is uniquely identified. This page, and subpages of it, can be used by users to record information about themselves or to test and draft new content. Pages of the form "User:UserName/Foo.js" or "User:UserName/Foo.css" can only be edited by the user themselves or by administrators.

3: User comments[edit]

This namespace is the comments namespace associated with the User namespace. Pages in this namespace are mainly used to leave messages for particular users or inform them of discussions that may be of interest to them.

4: Project[edit]

This is a content namespace that is normally used for meta-discussions related to the operation and development of the wiki. It has no special properties.

5: Project comments[edit]

This is a comments namespace that is normally used for discussions related to the associated content pages. It has no special properties.

6: Image[edit]

Example.jpg

The Image namespace is used to store metadata for images, videos, sound files and other media accessed via the Media namespace. Each file has a corresponding page in the Image namespace which is often used to hold licensing data. Linking directly to a page in this namespace instead includes the media file inline in the page: [[Image:Example.jpg|thumb]] produces the image to the right. See Help:Images for more details of this link syntax. To create an internal link to the file page, you need to add a colon to the front of the namespace: [[:Image:Example.jpg|thumb]] produces Image:Example.jpg.

7: Image comments[edit]

This is a comments namespace that is normally used for discussions related to the associated media files. It has no special properties.

8: JAMWiki[edit]

The JAMWiki namespace is used to hold system messages and other important content. For instance, the page JAMWiki:ApplicationResources.properties contains translations used on the site.

9: JAMWiki comments[edit]

This is a comments namespace that is normally used for discussions related to the associated system messages. It has no special properties.

10: Template[edit]

The Template namespace is used to hold templates, blocks of text or wikicode that are intended to be transcluded in several other pages. To facilitate this it has the special property that it is the default namespace for transclusions: the wikicode {{Foo}} is equivalent to {{Template:Foo}}.

11: Template comments[edit]

This is a comments namespace that is normally used for discussions related to the associated template pages. It has no special properties.

12: Help[edit]

The Help namespace is usually used to hold help files, instructions and 'how-to' guides. It has no special properties.

13: Help comments[edit]

This is a comments namespace that is normally used for discussions related to the associated help pages. It has no special properties.

14: Category[edit]

The Category namespace contains categories, dynamic lists of other pages. To facilitate this, linking directly to a category page does not output an inline link, but instead includes the page into the associated category page. So the code [[Category:Help]] causes a category link to appear at the bottom of the page (at the bottom in the box marked "Pagecategories"). Clicking on that link takes you to the category page, where this page is visible in the category list. To create an inline link to a category page, you need to add a colon to the front of the namespace: [[:Category:Help]] produces Category:Help. See Help:Categories for more details on category link syntax.

15: Category comments[edit]

This is a comments namespace that is normally used for discussions related to the associated category pages. It has no special properties.

Starting with JAMWiki 0.9.0, namespace names can be translated into languages other than English and individual namespaces can be renamed, as set by a wiki's system admins using the Special:VirtualWiki interface. These names are known as the 'localized' namespace names. However, all namespaces have a 'canonical name', the original English name which will work on any installation of JAMWiki. So linking to User:Foo will always locate the user page for the user foo, whether the wiki is in French (where the localized name would be Utilisateur:Foo), Russian (Участник:Foo) or Hindi (सदस्य:Foo). The canonical namespace names are given in the table to the right along with their localized names on this wiki.

Custom namespaces[edit]

See Manual:Using custom namespaces for more information.

Some wikis may wish to organise their content in ways that do not fit into this standard set of namespaces. A wiki may define additional namespaces to facilitate this; these namespaces behave exactly like normal namespaces, and generally have indices greater than or equal to 200. These custom namespaces generally have no special properties.

Identifying namespaces[edit]

There are a number of ways by which the namespace of a particular page can be identified:

Magic words

The magic word {{NAMESPACE}} returns the value of the namespace the page is in.
