[talk-au] Tagging WebSite Links (like wikipedia, wikidata)

[Andrew Harvey]

Hi Andrew,

I don't have a strong preference, but in the same way as
https://wiki.openstreetmap.org/wiki/Key:wikipedia and
https://wiki.openstreetmap.org/wiki/Key:wikidata only include the page
identifier (language/title) and the wikidata ID, and not the full URL, I
would suggest do similar, like ref:nhvr=abc123.

In terms of including an external (eg NHVR) reference on each OSM object, I
think that's okay so long as the OSM community can also lookup those
references and ensure they are correct (for the right road/road segment),
fix them, or add missing ones etc. If you were proposing a tag like
ref:nhvr=abc123 where abc123 was private/internal to NHVR it becomes more
problematic as mappers can't verify/fix them.

If your data varies a lot along a road way, I'd consider if it makes more
sense to skip the reference/link and just publish it in a way that
references OSM, etc. using OSM NodeIDs, OpenLR strings (for example like
what Mapbox do with their traffic
https://docs.mapbox.com/data/traffic/guides/data/).

I'd also see what we can do in terms of adding data directly to OSM. Road
widths can be mapped
https://wiki.openstreetmap.org/wiki/Key:width#Width_of_streets, gradient
could be mapped with https://wiki.openstreetmap.org/wiki/Key:incline.
There's some discussion needed though if we want to mass map this kind of
data into OSM.
