Components of street addresses

Hi all,

although it might be slightly off topic I'm sure there is enough knowledge 
/ network in this group to help me further.
The dutch government opened up their complete address and building 
information registry, I'm looking into making this available as Linked 
data so I'm investigating the components.
The addresses in that data set are completely split, so there is a street 
( which is a resource ) and separate house numbers and floor level 
indicators.
I've been looking for a few days, but so far i only could find the 
combined property in the various ontology's which deal with address data ( 
vcard etc )

I was wondering if someone could help me a bit further, and if we the 
dutch are the only ones having addresses in this way ?

If there is interest I could demo it during the F2F

With kind regards/Met Vriendelijke Groet
