When downloading a larger data-set (ex. all of a certain place) it would be nice to also get the information in which projects the downloaded observations belong to. The information about the “collection” projects is currently not included in the metadata of the observations as far as I’m aware. I’m aware that collections work differently than traditional projects and that adding this information to each observation is probably an resource intensive process.
I did add a little more context in thsi post:
