[OSM-talk] Adding wikidata tags to the remaining objects with only wikipedia tag

I'm trying to understand this.

If I noticed an inception date on a information sign next to a
building, is this original research or a secondary source ?

If a Wikidata contributor/Wikipedian researches websites like Orbis,
Onroerend erfgoed, etc and finds different inception dates and records
them all, is it bad that s/he uses secondary sources instead of the
information sign on the ground ?

I wonder whether OSM is really always based on original research, or
whether we sometimes just want to believe this.
