Currently we are comparing different released sources. For example we
have a source for Building and Addresses which has unique objects.
While this specific datasets has only aggregations of buildings.
Another example is streetname labels:
TOP10 = Cadastre
NWB = National Road File
So it seems that Government offices are not integrated theirself. And
no, there are no shared attributesid's. Thus I am contacting both
offices if we could integrate the data with eachother, forming: linked

I'm hoping that something could spin out of this kind of massive data
availability where 'fix errors' is the new 'Share Alike'. No need for
database rights etc., because it is obvious: everyone can make the map
better, and it is backed by the government that you already paid for
to do so.
