Any page of this website may be translated in another language.

As for this site, the default language is French. Each page, as this one, has a path, like 
[[en:wiki:traduction|en:wiki:traduction]]. The system finds the corresponding page in another language by following a simple rule: the two letters for the language are inserted as a prefix (except when the language is the default one). That gives [[wiki:traduction|wiki:traduction]] in French, translated into English in [[en:wiki:traduction|en:wiki:traduction]].

Evidently, the approach suffers from a major weakness: some pages may have paths where some elements are in another language than the page content itself. Like [[en:wiki:traduction|en:wiki:traduction]] instead of [[en:wiki:translation|en:wiki:translation]]. Actually, [[en:wiki:translation|en:wiki:translation]] may be created anyway, but as far as the system is concerned, it will be the translation of the French page [[wiki:translation|wiki:translation]], that will also have to be created.

Enough said... Some research are still going on in order to understand what a good multilingual website would be, one that would offer automated help to manage sets of translated pages...
