Editing Help:Interwiki linking (section)

=== Prefix codes for linking to Wikimedia sister projects<span class="anchor" id="Project codes"></span> ===
:''See also [[Wikipedia:Wikimedia sister projects #Linking between projects]] for a compact overview''
Unless a [[metawikipedia:List of Wikipedias|language code]] is added, the following interwiki prefix codes link to the Wikiprojects in English.

Note that some links don't work as expected within the same project, e.g., [[metawiki:Test|meta:Test]] on [[metawiki:|Meta]] itself would mean [[metawiki:Meta:Test|m:Meta:Test]], a different page. Outside of Wikimedia sister projects, only [[metawiki:Test|metawikipedia:Test]] might work for [[metawiki:Test|m:Test]].

Wikimedia projects with different language editions are '''bold'''.
<!--DO NOT ADD ANY WHICH ARE NOT ALREADY LOCATED AT
     http://wikimediafoundation.org/wiki/Our_projects

     Note from December 2015: The above page is too general. The correct link seems to be the one in the hatnote:
     https://meta.wikimedia.org/wiki/Complete_list_of_Wikimedia_projects

|}<section begin="iwl-tables" />Other current Wikimedia prefixes: [[betawikiversity:]], [[dbdump:]], [[download:]], [[gerrit:]], [[mail:]], [[mailarchive:]], [[otrs:]], [[OTRSwiki:]], [[outreach:]], [[quality:]], [[rev:]], [[spcom:]], [[sulutil:]], [[svn:]], [[ticket:]], [[tools:]], [[tswiki:]], [[wm2016:]], [[wm2017:]], [[wmania:]], [[wikiconference:]].<section end="iwl-tables" /> See a complete list of current and old but still working prefixes for all Wikimedia wikis at the [[Special:SiteMatrix]]. See a complete list of all possible interwiki prefixes at [[Special:Interwiki]].

Some of the '''long forms''' do not work as expected within the same project; for example <kbd><nowiki>[[meta:]]</nowiki></kbd> does not work on Meta, while <kbd><nowiki>[[metawikipedia:]]</nowiki></kbd> does. This depends on the configuration of the wiki and where the names are stored (see also next paragraph). The '''shortcuts''' work everywhere. The [[m:Interwiki map|interwiki map]] on Meta lists many prefixes, among others, <kbd><nowiki>[[wikipedia:]]</nowiki></kbd> for the English Wikipedia, working from any Wiki supporting the Meta interwiki map, not only from MediaWiki wikis. Some prefixes work only with a page, for example: [[wikipediawikipedia:]] (fails) vs. [[wikipediawikipedia:Interwiki link]] (works). These prefixes are case insensitive.<section begin="iwl-text" /><!-- This template needs fixing:
One-letter prefixes (as a live check on the table): {{for loop|call=If interwiki link show||a|b|c|d|e|f|g|h|i|j|k|l|m|n|o|p|q|r|s|t|u|v|w|x|y|z}}
-->

The shortcuts are just interwikis with different histories. Wikipedia, Wikiquote etc. point to the English versions and are also included in the standard MediaWiki interwiki table (IIRC); w, q, b, wikt etc. are used like interlanguage wikilinks to link to the sisterproject in the same language (so [[w:it:b:]] is equivalent to [[Wikibooks:it:]]).

Non-Wikimedia interwiki codes have a limitation, that they can only be used through a link. For example, the entry for "[[wikt:John|John]]" on Wiktionary, a Wikimedia project, can be accessed by <kbd><nowiki>[[wikt:John]]</nowiki></kbd> or http://meta.wikimedia.org/wiki/wikt:John. However, the latter method does not work for non-Wikimedia wikis. For example, the main page on the Mozilla Wiki can be accessed via <kbd><nowiki>[[MozillaWiki:Main Page]]</nowiki></kbd>, but http://meta.wikimedia.org/wiki/MozillaWiki:Main_Page results in an error. In these cases, Special:Search can be used (http://meta.wikimedia.org/wiki/Special:Search/MozillaWiki:Main_Page). You can see [[m:Special:Interwiki|the Interwiki special page]] for a list of "forward" and "non-forward" prefixes.
