[OSM-talk] import of dataset for new zealand

[Cartinus]

Anybody wanting (semi-)read-only tags in OSM should read the discussions about 
the edit war in Cyprus to see how futile they are for this purpose.

Can't edit a tag? Just delete the whole object and create it anew.

For a more practical example related to mass imports:
The waterbodies from the AND import in the Netherlands are often less accurate 
than the Yahoo aerial imaging that has recently become available here. Now I 
can "tug" at the polygon from the AND import till it conforms better to the 
Yahoo image and put something in the source tag that reflects both sources. 
If the source tag was read-only, then I'd delete the polygon from the AND 
import and trace a new one from the Yahoo image. The net effect would be a 
break in the edit history, because nothing links the new polygon to the old 
one.
