Are you a part of the OSM community? Last time I checked bulk inserting data from official datasets was not always welcome[1]. There's also the following glaring issue:
> Licenses - We are only interested in 'free' data. In fact we must be able to release their data with our OpenStreetMap License. This means it's OK to use Public Domain data; for other sources, please check license compatibility.
While I would definitely like to see official datasets get incorporated into OSM, an initiative to make public institutions embrace openness and data re-use is required beforehand. Then there are the technical difficulties of synchronizing OSM with the latest official data and ensuring correctness.
Why not simple pay/hire a bunch of geeks to upload all this data to an already existing platform, namely OpenStreetmaps.org ?
So this is where my European tax-euro's go to...
