[Corpora-List] Language codes and spelling reform

[Lars Aronsson]

According to http://en.wikipedia.org/wiki/List_of_ISO_639-2_codes 
there are separate language codes for Old English (ang), Middle 
English (enm), Low German (nds), Old High German (goh), Middle 
High German (gmh) and Alemannic (gsw), in addition to today's 
English (en, eng) and German (de, deu, ger).

But is there any systematic approach to name and identify the 
variants of German from the 19th century (Thier, illustrirte), 
20th century (Tier, illustrierte), and 1996 reform (f, sss)?  Are 
there names and codes for the various historic stages of Nynorsk, 
Danish with "maae", pre-1906 Swedish with "dt", etc.?
