Can I use a Relation to join a restaurant and its patio?
I've got a patio for a restaurant tagged as leisure=outdoor_seating. That page says you can add operator=* as a string, but I'm wondering if I can add a Relation between the patio and the restaurant. This is really for semantic reasons, because if the restaurant changes its name or gets a new owner, it would be nice if the patio didn't then have out-of-date information.
I don't see a Relation type that's relevant. I don't want to just start doing my own thing, so does anyone know of a way to use a Relation here, and if not, is that something that can be proposed?
Thanks for all of the responses on my other questions, btw. This community has been very helpful.
My general recommendation with relations: If you can do something without a relation, do it that way. A lot of people don't understand them and some editor software can't manage relations well, so there is a big chance that someone will mess it up accidentally in the future.
Maybe you can tag on the restaurant that outdoor seating is mapped as a separate element with outdoor_seating=separate. It's not used frequently, but separate means that something is mapped as a separate element.
If you still want to do a relation you can use a site relation. You can use that for any kind of POIs. I don't recommend this though for 2 members. Example. Overpass query for all site=restaurant: https://overpass-turbo.eu/s/1QjJ
If you afraid someone will forget to change the operator, the same editor can forget to update the relation as well, so I think you can't win this battle.
