Thanks for working on this. I had been meaning to reopen the proposal.
No need to introduce a new key. natural=mountain_range is fine, and
has been in use.
For me the key 'natural' is not good. It has a common meaning that goes
against the OSM definition.
Not all land forms are 'natural' by the common meaning of the word.
So I'd rather use a word that says what it is without any confusion - a
land form.

Yes, both of these are good. If a way is used it should follow the
natural=ridge ways.
Not all part of a range have ridges - some have plateaus.
A natural=mountain_range will probably consist of several ridges which
meet at natural=saddle points.

These will be quite hard to define. Do you go all the way down into
the valley or plains till the land is flat? Or only surround the
higher elevations?
Some have already been mapped that way. I don't know of the
source/method of determination.
I’d recommend sticking with a linear way or node.
If a node then some may want a relation - the node as the lable, and
other nodes that are peaks of the range, ways that are ridges of the
range .. and so on.
If a way some may want a relation - the ways as the spine, nodes as
peaks .. and possibly some ways as side ridges ...
???
I don't know.
For me I'd just map the spine as a way.

Hi,
There appear to be 2 competing tags for use with mountain ranges.
Neither have any wiki documentation!
A) place=region, region=mountain_range
Mostly relations with outer ways only.
B) natural=mountain_range
Again as relations - with outer ways and at least some with nodes
representing peaks within the mountain range.
---------------------------------
So .. to combine them into one and standardise the format?
Introducing
C) landform=mountain_range
To map as a node - centred on the area, a simple open way along hte
spine of the range, a closed way on the area of the range or a
relation
consisting of ways forming a closed are of the range.
No entry of peaks, ridges etc as these will change with new
entries, and
can be forund by searching inside the area if the area is mapped.
-----------------
The new tag can run with the older tags so they will still exist
while
the new tag establishes itself.
Well, what do you think?
