We had a discussion some time ago on the talk list regarding how the
idea of wikidata IDs already clashes with the idea of on-the-ground
verifiability and the established rule not to have external IDs in the
OSM database. My current view of that discussion is largely outlined
Having additional tags representing abstract concepts and categories of
features would further exacerbate this problem.
If what you want to tag part_of:wikidata representas a spatially defined
and as such verifiable concept you should map it in OSM and what
features are part of this derives from the spatial relationship and
existing tags in OSM - in other words part_of:wikidata would be kind
of 'is_in all over again'. If what you want to tag with
part_of:wikidata is a class of objects or category you should look for
an existing tag or invent a new tag describing this class/category and
you can add the wikidata ID to the tag page on the wiki describing the
relationship (which again of course is not necessarily a 1:1
Tagging something like part_of:wikidata instead of either of this looks
to me like delegating the recording of mapping information and with
that the authority of defining concepts and classes to an external
authority (wikidata) with ultimately incompatible standards.
