Per this request, we should allow some sort of a integration between wikidata and maps service.
Open questions:
- should we extend geojson spec to support this?
- Should we wait for half a year until wikidata query pages are ready, and instead have an attribute instead of changing geojson?
- Should it be a drop-in replacement from wikidata query to a pre-generated query? (query pages will not support dynamic, per request parameters)
- How should it coexist with the regular geojson objects?
- What syntax should be used for text description? should there be a wikitext/lua transformation from wdqs response into a title/description fields?
