Content, page and user language
Semantic MediaWiki is mostly concerned with the following three languages provided by MediaWiki:
- Content language (or site language), the language in which the content of a page is written in wikitext by default
- Page language or page content language, the language in which the content of a page is explicitly written in wikitext (see SIL)
- User language, the language a user chooses to operate in
SMW 2.4 implements some rudimentary support to incorporate some of those different language options and more closely pays attention to the intended language of a content (denoted through the page content language).
MediaWiki also operates with other so called language variants which are of lesser concern for Semantic MediaWiki.
