[OSM-talk] ADD import (Antarctica natural features and POIs)

[Christoph Hormann]

There does not seem to be any serious objection so i am going to proceed 
converting the data.

Two minor changes:

- use capacity:persons instead of capacity for the research station 
capacity value.
- only maintain the ADD:* tags derived from the original data attributes 
for the coastlines and POIs, not for the streams.  It is doubtful how 
useful this data will be in the future.  In case of the coastline it 
could help deciding on future updates though (since age and resolution 
of the ADD data varies quite a lot).

The whole matter of source metadata to me seems to be an open issue in 
Openstreetmap.  One can introduce such data through tags but there is 
no mechanism ensuring this information stays valid - geometries and 
tags can be and are changed independently so there is no way to verify 
if source attributes are actually valid without looking in detail at 
the whole editing history.

I know that because of this the recommendation is to apply source tags 
to the changeset rather than the geometries.  This is not feasible in 
case of fine grained attributes like the ADD coastline though where 
every way has different attributes.
