Hi Peterkrauss,
Thanks François, important topics...
I second the need you mention of a relation in a whole.
Wikidata references should be unique as possible in the db.
It seems the basic premise,
"Wikidata references should be unique as possible",
I will use your phrase from here.
There are more cases in of sample-country DE where it is not unique,
https://wiki.openstreetmap.org/wiki/User:Krauss/Wikidata-question2
Using route or site relations when appropriate is a good solution.
Ok, lets elect the OSM Map Features that are Wikidata-good-solutions
* "type=boundary" (6,525,236 elements)
* "type=route" (30,257,877 elements!) and complements as
"type=route_master".
* ... more good solutions?
PS: "type=site" was classified with status "abandoned", at
https://wiki.openstreetmap.org/wiki/Relations/Proposed/Site
All the best
François

Hi,
Seems a commom quality problem of part/whole confusion in the
Wikidata attribution or OSM's POI reference... And where there are a
need for "enveloping parts into a whole".
Example:
* The railway-whole concept, Anhalt Railway
https://www.wikidata.org/wiki/Q319837 [1]
* The railway-parts concept, a fragment of the Anhalt Railway,
https://www.openstreetmap.org/way/539934418 [2]
* The error: 197 fragments with the Q319837 concept
* The need: a relation to "envelope Anhalt Railway" as a whole
