That is what I am not sure about. The dcat specification itself is ambiguous. If you click on the link of „dct:language“, it brings you to
http://dublincore.org/documents/2012/06/14/dcmi-terms/?v=terms#language
and that defines languages as an RFC 4646 value, which includes ISO 639-3 and much more. But if you follow the links 1 and 2 of
dct:LinguisticSystem 
Resources defined by the Library of Congress (1, 2) SHOULD be used.
 you are lead to the ISO 639 one and two codes. So it is a bit difficult to understand what it actually means: use dct:LinguisticSystem as specified in dcat.

Cheers,

Felix
