API question: mapped versus owning collections for items

[John Mulligan]

Hi folks,

New to dspace, and sorry if this has been answered before but I couldn't find it on your confluence wiki.

Is it the case that

1. Coming from the /collections/:ID endpoints
   1. You cannot see the items that the collection owns
   2. You can see the items the collection has had mapped to it
2. Coming from the /items/:ID endpoints
   1. You cannot map an item to its owning collection

If so, then am I wrong in thinking the only way to see an owning collection's items is to search for items that have that collection as owningCollection?

Confirmation (or correction) will suffice for me to keep going here, but if all of the above is correct, then I guess I'd be interested in why one wouldn't want to be able to see an owningCollection's items from the collections endpoints?

Thanks!

John Mulligan
