Dear Rafael and Andreas,

Thank you for taking the time to review the import plan and for you
recommendations, which are helpful. Here are a few comments:

1) Architect:
Yes, we can remove "ukjent" (unknown) as it does not provide any
additional information.
The "type" in "Linstow type" usually means that the building was based
on a general plan for a church of this size by architect Linstow,
perhaps used for more than one church. Will check.
The place name in architecht="Ole Halvorsen, Bergen" usually means that
there are more than one architect with the same name. Will check.
We will review the list of architects before the import.

2) Languages:
There is already a description in the work flow section of the import
plan on how to handle multiple names for a church. Existing names will
be kept. The N50 background map will show the official/primary name,
including Norwegian and Sami names where both are required (including
the correct order).
We can expand the workflow section and make it even clearer. 

3) History:
The history should be kept. Will add that to the workflow description.

4) Building footprint:
Aerials will aid in deciding which building footprint is the best to
keep. Will add that to the workflow description, including a warning
against altering buildings with 3D tags.
The quality of the footprint in the import is high.

5) End_date:
Some of the churches with an end_date has now a different function. We
can remove them from the import as they are not important buildings
anymore in this context.
Others with an end_date have burnt down and are now ruins.

6) Ruins:
There seems to be different views on how to tag a ruin (as reflected on
the wiki discussion pages), and we are in fact unable to conclude which
tagging is recommended in OSM based on the wiki.

> I don’t think it has been discussed thoroughly, but the practice in Norway seems to be to use only one name/language in the name=* tag. 
> If the church is located inside “samisk forvaltningsområde” (≈ “Sami administrative area”), the Sami name should probably be used in the name=* tag, and the Norwegian name added as name:no=*. Sami language has official status in the municipalities that make up “samisk forvaltningsområde”. These are the municipalities:
> Unjárga – Nesseby
> Deatnu – Tana
> Porsanger – Porsáŋgu – Porsanki
> Kárášjohka – Karasjok
> Guovdageaidnu – Kautokeino
> Gáivuotna – Kåfjord – Kaivuono
> Loabák – Lavangen
> Divtasvuodna – Tysfjord
> Aarporte – Hattfjelldal
> Raarvihke – Røyrvik
> Snåase – Snåsa
>> 4) -42800 (Bø kyrkje):
>> "name"="Bø kyrkje" -> But the wiki isn't clear on what you will do when it is already mapped with a different name. In this case, the name in OSM is "By kyrkje", so which one will you keep if names are different?

>> The church is also mapped as an area (building footprint). But the wiki doesn't clarify what footprint will remain, if the one present in OSM or the new one from the import.

>> "architect"="ukjent" -> ukjent means unknown, isn't it? I guess in this case it would be better to skip the architect tag, or change it to "architect"="unknown", although it seems there isn't any object in OSM with the "architect"="unknown" key&value combination according to taginfo [3]. I've checked, and there are 266 churches with this "architect"="ukjent" tag.
