You cannot infer the language from the site identifier. "enwiki" is a site identifier. The software allows having multiple sites for the same language. For instance you could have an entity that is also described on the English Wikitionary. Or an entity described on a third party website as well, such as a movie on imdb. Unfortunately it looks like we are not yet providing an actual API for accessing this information.

I suspect this is your best bet for now. We have a mechanism for change propagation to mirrors, though right now the only implementation on top of this that we have is WMF specific. Volunteers and third parties can however create their own implementation suitable for non-WMF use.
