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?
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.
