Project:Namespaces

Structure of contents on MediaWiki.org

	Namespace	License	Contents	Examples
MediaWiki logo	Main	CC BY-SA	All general information about the software.	Introduction, developers, history, upgrade information, contests, press, specific styles/skins.
Manual logo	Manual:	CC BY-SA	All technical or more detailed stuff behind the surface, that is not part of the basic help pages (full handbook, mainly for people setting up their own wiki).	Main and detailed parts of Meta's MW help, technical reference, configuration settings, hooks, ... (not including extensions).
Extensions logo	Extension:	CC BY-SA	All extensions and directly related stuff.	Extensions and tools, that are not part of the default MediaWiki distribution.
Project icon	Project:	CC BY-SA	Organization of MediaWiki.org, this NS should be as small as possible.	Hints for translation of the main introduction, coordination of pd help pages ...
PD Help icon	Help:	public domain	Set of basic help pages for users of an existing wiki (formatting etc.) The first aim is a complete English version, that can be shipped with the MW distribution.	Like Wikipedia's help: start a new page, formatting, insert a picture, use of simple tables, how to categorize, revert vandalism ...

Notes:

NS:Help is thought to be a basic stand-alone help, this namespace must be coherent when it is ready, and should not contain any internal links other than to itself therefore. (still needed: task T6469 -> extra sitenotice!)

NS:Manual can link to wherever; the basic help could be seen as a "small" addition to the full "manual".

All namespaces have an associated talk namespace, where related discussion is held.
