know that in Israel, @SwiftFast uses a template to keep them in sync for
gas stations and ATMs, but we need a more generic solution.

A simple query could find all wikidatas pointing to enterprises, producing
cases like this (these are just the first ones i found)  -
http://tinyurl.com/yby8564c
* nodes 192051528, 243017574 -- villages marked as ski resort, place=hamlet
or village
* node 285833428 - a ski resort with place=locality
* node 436622732 - a mountain AND a ski resort in WD, with natural=peak in
OSM
* relation 128277 - a commune and a ski resort, marked as admin boundary

An alternative would be to maintain a whitelist of all known brands, either
on a wiki, or as an additional wikidata "instance-of   Q431289".
