Thanks a lot for showing interest!

Good, we will not add addr:country. I agree too :) The wiki-page will

When I say POIs, I mean nodes with either amenity, shop, name etc. The
plan is to let such POIs with address information remain in peace, and
then add nodes (or buildings) with only address information. At many
places there are several POIs on one single address. Having one and
exactly one node (or way) with only address information will simplify
maintenance and provide users of common rendering engines with one
visible number on the map.
> 3. Why are you not importing buildings along with the addresses?
I'm not sure if I understand your question. There are no buildings in
this dataset from Statens Kartverk. If we want them, we will have to
draw them, and then we won't be done with the import in a very long
time - considering the number of houses per person here. :) We are of
course always trying to draw new buildings though..

The addresses in the dataset are nodes. Therefore we prefer to import
them directly as they are with the 4 addr.*-tags. Whenever there
already exists a building in OSM with the same address, the node for
this address will not be imported. Some people in the Norwegian
community wanted to do it like in Denmark - having only addresses on
nodes, but others opposed this. We therefore now aim for a solution
where both are allowed - but the new imported adresses will be nodes.
The web-service that is continuously comparing the data with the
dataset will accept both

Luckily, the dataset contains fully written street names! This is
therefore not a problem for us. It has been discovered some typos in
the dataset. For this we have a correction list in xml-format:

Thanks for the tip. Several of us already know about this tool, and we
are using it to add missing roads and names. It's great!
