I think that the owners should accept that once they put some data here, the data that they already sent should be here forever. It do not think it will be a problem for producers to accept that, as it is a classical requirement. Otherwise it will be really difficult to manage the takedown of archive data, both for windy and other users.
What happens if someone makes a png map of worldwide yearly temperatures… Need to remake the image everytime someone wants to get his data back? Do you see my point?
Of course, it's up to you. I am just trying to give some advice.
Cool for the API! Thanks!
