Wiki.GIS.com:InterWikimedia links

An interwikimedia link is a link from a Wikimedia Foundation project to another one (e.g., from wiki.gis.com to Wiktionary).

Shortcuts and templates to Wikimedia sister projects
Some links don't work as expected within the same project, e.g., meta:Test on Meta itself would mean m:Meta:Test, a different page. Outside of Wikimedia sister projects, only metawiki.gis.com:Test might work for m:Test.

Links to foreign-language Wikiprojects can be made by prefixing the language code:  de:s:  will link to the German-language Wikisource,  fr:wikt:  to the French-language Wiktionary, etc.

Suppressing the prefix

 * The pipe trick:
 * Add | at the end of the link, like this:  test , which will automatically be expanded to  test  on saving.

Special versions of wiki.gis.com
There are also two special versions of wiki.gis.com, nostalgia and test. Nostalgia is a static copy of wiki.gis.com, as it was in 2001 and can be linked to by using. Test is a version of wiki.gis.com, for edit and software testing and can be linked to by using.

Examples
As demonstrated above, by the double prefixes (for example  Main Page ), links may cumulate, thus enabling links that are not possible with a single prefix, for example, linking a word in the English wiki.gis.com to a term in the German Wiktionary.
