Looking for a vocabulary for NUTS and LAU

Hello,

I am working on a vocabulary for administrative subdivisions in my 
country (The Netherlands). Some of these are associated with NUTS and 
LAU levels, and I want to record those links. So I am looking for a 
vocabulary that describes what NUTS and LAU levels are and what the 
national equivalents of those levels are. Something like the overview on 
this page 
<http://epp.eurostat.ec.europa.eu/portal/page/portal/nuts_nomenclature/correspondence_tables/national_structures_eu>: 

http://epp.eurostat.ec.europa.eu/portal/page/portal/nuts_nomenclature/correspondence_tables/national_structures_eu

I did find data sets about NUTS regions, but they all seem to list the 
regions instead of explaining what they are. Examples:

http://nuts.psi.enakting.org/
http://nuts.geovocab.org/
http://rdfdata.eionet.europa.eu/ramon/nuts.rdf

Does anyone know of the thing I am looking for?

Regards,
Frans
