Traditionally, in Wikipedia e.g. [[nl:Ellemelle]] produced a link on the left, indicating that that was the Dutch version of the article. How can I set up this feature in my mediawiki installation? Extension:Interwiki, for instance, allows for setting up this kind of relation, but afaik it does so within the artcle, not in the left column, outside of the article.
I hope I could express my point.
Thank you in advance for your help.
You don't need an extension. See Manual:Interwiki. be sure you're using language codes (de, en, es, it...) and not any custom code as iw_prefix, otherwise they can't be interpreted as an interlanguage link.
Thank you for your answer.
I placed an incomplete question, so I got an incomplete answer.
We are planning two wikis, describing different versions of a standard, and if there are features that both wikis share, then we would like to place an interwiki link.
With your hint I got it solved quite straightforward by adding entries to Names.php like
'2' => 'Version 2.x', # Version 2 of our standard
