Interwiki is a MediaWiki extension that allows to use intenal links format (i.e. [[something]]) instead of external ones, to link to other languages pages and some external wikis such as Wikipedia, MediaWiki...
It uses a prefix table to redirect addresses, wich is stored in the page : Special:Interwiki.
[[:<language_code>:<Full_page_name>]]
Here, available languages codes are : de
(🇩🇪) , en
(🇬🇧 , 🇺🇲), es
(🇪🇸), fr
(🇫🇷, 🇧🇪, 🇨🇦) and ru
(🇷🇺) and atys
for common [1]
The Trad Template displays a small languages banner as on the right of this line, which flags, when displayed, are linking to other languages pages. It can also provide a translation status information. See the Trad Template page for full documentation.
{{Trad |DE = Page |DEs= (translation status code) |EN = Page |ENs= |ES = Page |ESs= |FR = Page |FRs= |RU = Page |RUs= |H = (1 for horizontal) |palette= Theme |ref= Page_link |com= Comment }}
Interwiki allows to insert an "In Other Languages" Menu in the "Navigation Bar"[2] which provides links to translated pages exactly as the Trad template does. To do so, just insert blind links to the translated pages with the following syntax (no leading ":" ):
[[language_code:Full_Page_Name]] (i.e. with the namespace)
For example, this page's "In Other Languages" Menu is obtained with :
[[de:Help:Interwiki]] [[en:Help:Interwiki]] [[es:Help:Interwiki]] [[fr:Help:Interwiki]] [[ru:Help:Interwiki]]
Note that the Help: namespace does not need to be translated [3].
Linking to other wikis follows the same rule, just use the Special:Interwiki prefixes instead of language ones; (wikipedia linking secifies the language AFTER the prefix).
Transclusion of other languages are also possible. To include a page of another language just use:
{{:<language_code>:<Full_page_name>}}
or, more generally : {{:<prefix>:<Full_page_name>}}thus exactly the same as if the page was in the same language space, but the beginning language code. Please note that the <noinclude></noinclude>
and <includeonly></includeonly>
seem to be ignored, and the whole page is transcluded.
As an example, this page is not translated but transcluded to the other languages instead ( this could change in the future).
