Germany has a classification known as
Klassifikation der Berufe 2010 (KldB 2010)
Which is produced by the Bundesagentur für Arbeit (German Federal employment agency). Previously there were two standards used in Germany, but since 2010 then this has been combined into this single standard.
This document in English http://doku.iab.de/fdz/reporte/2013/MR_08-13_EN.pdf provides more detailed information.
