I added the following to the talk page of that article:
Nodes/Ways/Relations
Nodes, Ways and Relations. Those are the primitives we have currently in
OSM. The way I see it, it would be interesting to have something like
Adresses, Streets, Public_transport_stops, Bus/Tram/Train lines,
Route_variations, etc.
These "Primitives" would contain pointers to the N, W and R primitives that
are currently used and that were previously used as componenets of the
higher level Primitives. It's these higher level primitives that may make
sense to store in a WD instance.
In a way we already do parts of this using relations. What relations don't
offer is the historic part of the data. Digging into the history of OSM
primitives is a very hard thing to do. Overpass API solves part of that
problem.
For the above proposal it's important to keep the WD instance up-to-date
with the minutely diffs.
At the moment the best way to "marry" OSM and WD is by adding wikidata and
*:wikidata to the OSM primitives. There is still a lot work to be done
there.
If such a WD instance dedicated to OSM ever takes hold, it may be
interesting to cross link Wikidata to/from it.
