@Kees 59: It's one of those relations which only serve to group together various POI by similarities (i.e. a category), something which is discouraged on OSM: https://wiki.openstreetmap.org/wiki/Relations_are_not_categories

Incidentally, this was once formally proposed but got rejected by a majority for these reasons: https://wiki.openstreetmap.org/wiki/Proposal:Relation:person
A draft got started again but with no progress: https://wiki.openstreetmap.org/wiki/Proposal:Relation:person_(rewrite)

In any case, this is something which should be IMO removed from OSM because of limited advantages (especially compared to simply using Overpass + Wikidata).
