Hi Stephan! Yes, a relation can be made up of a relation: no problem with that, AFAIK. In your particular case, anyway, I'm afraid there is something wrong: https://www.openstreetmap.org/relation/1937535 (name=MuseumsQuartier) is tagged as "building=yes" and also with

Yeah. The "/other/" solution could be to "/namespace everything/", so you could tag building:whatever_property_key_you_want and amenity:whatever_property_key_you_want, applied to the very same object. But we're probably too late for that and apparently many seems to hate this latter solution.

Like in the thread opening email, where there is an amenity that occupies the whole building, we put amenity tags on the outline. I generally support adding more granularity to start_date, but feel like start_date:* might fit better than *:start_date. Anton Klim > 16 февр. 2019 г., в 21:40,

I'm a bit confused by this thread, somehow I have the impression I missed something (that's why I left TOFU in this mail). Anyway, I'd like to summarize: There are many-many objects (most of them buildings - 96%) tagged with start_date=* - I think, that's great. start_date is quite well

I think those would mostly be historical uses. Considering it’s part of an abandoned proposal, don’t think there would be much new entries. Plus, buildyear implies you can specify a year, instead of a date, like you can for start_date and its possible offshoots. Ant > 16 февр. 2019 г., в

Hi! I have some thoughts in the start_date tag, as I find it a bit too vague - meaning start of what? Example: There is this museum, which openened in 2011, but the building is much older, it was built in 1725: https://www.openstreetmap.org/relation/1937535 An option would be to prefix
