I need some help @openstreetmap.

UPDATE: Thanks for all the help!

What do I do, if a business has closed down, and then a new business has taken over the same place?

Do I mark the previous business as “does not exist” and add the new one, or do I edit the existing one?

@danish @openstreetmap in general edit the existing one, all elements in OSM are versioned and it is considered best practice to maintain the history of objects.

@danish @openstreetmap naturally I do have to add one nerdy and nitpicking observation. It is actually "nearly all elements in OSM", as versioning was introduced with API 0.6 https://wiki.openstreetmap.org/wiki/API_changes_between_v0.5_and_v0.6 in March 2009, elements deleted before that date are literally gone.

@simon @danish @openstreetmap

But only when it is the same object. If it was a POI marked on the map as a node, then it is better to delete the old node and create a new one.

Otherwise we will get something like this: https://osm.org/node/2/history

@foxy @danish @openstreetmap you need to differentiate between reusing existing nodes for other purposes (as in your example), which irl works against preserving history, and using an existing element for a new or different facility in the same place (there is some grey area there obviously).
