My overarching concern is that if this import is done, future imports will use the "but we also have Wikidata links" argument for justification. What we have here is a third-party database whose object identifiers we add to OSM as tags in order to make linking things easier. This is something that has often been requested by people but never been granted on a large scale because we always said that it would be an abuse of our database and our mapper's patience to offload everyone's and their dog's linking requirements onto us. Imagine every single stretch of road being tagged with three different proprietary (or at least competing) identifiers of traffic information providers, or similar payload tacked onto OSM. I'm not saying no to a Wikidata import but I would like the proponents to state clearly what makes this import special - why this and not, for example, Ordnance Survey TOIDs or IDs of Mapillary photos? I would like to define high hurdles for such an import. The import costs us a lot (in terms of mappers having to spend time to understand the tags and know how to handle them when they edit an object, more quality checks, etc.), and it must be proven - or at least expected - to offset that cost by making itself useful. It's ok of this particular import clears the hurdles but at least I can then use the hurdles if the next guy in line comes along and wants to import his keys too. Also, I note that Rob wrote: "We have our own restrictions (verifiable on the ground, not changing to frequently) in OSM. A link to wikidata allows us to continue with these restrictions but still allow people to get at interesting non-geographic data." And Andrew said: "A few more points: This isn’t a deletionists’ charter and we shouldn’t rush to unload any tagging onto Wikidata without discussing the removal very carefully." I am personally very much in favour of "unloading" non-geo-database tagging elsewhere. We started with marking restaurants (useful) and recording their names (also useful), classing them into fast-food or "proper" restaurants, then tagging what cuisine they have and how to contact them for booking a table, and meanwhile we're recording whether they have vegan food and what their opening times are and whetehr you can pay with bitcoin. We don't currently have anywhere to "offload" that information which is all useful for certain use cases, but once we have a working integration, I should very much hope that stuff like the menu and the opening times will be recorded either in OSM or in Wikidata but not both. Allow me one question in that matter as a Wikidata ignorant though: Are there any notability rules in Wikidata? For example, if we should one day decide that restaurant opening times should not be recorded in OSM but on Wikidata, can it then happen that someone records a restaurant's opening times on Wikidata only to have that information kicked out by someone else again for lack of relevance? Because if that were the case, then Wikidata would be relatively useless as a general offloading point for non-geodata.
