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://www.openstreetmap.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).

@danish @openstreetmap Edit the existing one to preserve object history. Good practice ist to change shop=something to disused:shop=something. This way the object can be re-tagged again as shop=somethingnew if it re-opens. If it just re-opens just skip the disused step.

Delete the old business and create the new business. Alternatively you can change the information to match the new business.

Please don't delete and recreate if you can. Keeping the history of points is useful, if you delete a point you will delete its history. Wiki article with more details: https://wiki.openstreetmap.org/wiki/Keep_the_history

Good article.

@infeeeee: Regarding deletion of history. Not sure if you simplified, but its not true that deletion of a point will delete its history.

As the article states

Deletion is not erasing the history of an object in the database.

It is just harder to find after deletion.

True! And the "Chronic" feature on www.openstreetmap.org is not really helpful for searching deleted nodes.
