We don't need to mint new language URIs, the US LoC are maintaining such
URIs based on the two-letter codes in ISO 639, e.g.
http://id.loc.gov/vocabulary/iso639-1/el

See http://id.loc.gov/vocabulary/iso639-1.html for the full list of
URIs. They are all defined as instances of
  http://id.loc.gov/vocabulary/iso639-1/iso639-1_Language
which is a subClassOf
  http://purl.org/dc/terms/LinguisticSystem

I believe that this vocabulary is a perfect fit for our needs.

Best,
Stasinos
