This fits very well the so-called “Northchain” in my local area It is mapped as a series of ridges and aretes. I want to group them into a relation, so the Wikepdia Article can be linked once only, and a search for the term will only yield a single result.
There seems no relation type adequate though. Anybody aware of one?
Alternative option: Draw a polygon (or multipolygon) around all of it. This would have the added value that everything inside (not just peaks, ridges etc) is known as “within Northchain”. Mountain range polygons are controversial because sometimes they are not perfectly verifiable. I have no knowledge of the “Northchain” to know if its possible to define a verifiable outer way or not.
This was debated a lot of times. There is one more tagging strategy, put mountain_range:wikidata=Qxxxx on every natural element of that mountain. But the former two strategies are probably more mapper friendly.
Finally got around this, after splitting the mapped ridges into natural=ridge and natural=arete sections, to match what is there on the ground, and then just drawing a single way along all of them to carry the natural=mountain_range, name=, wikipedia=, &c tags.
I just could not get around to dream up a polygon, where the situation is such a good fit for what the documentation says. Nominatim now finds it too. There is not even duplication, just several overlapping but different entities.
