Notes
	Does user authorization (Step 3) need to happen, or is it assumed that Administration requests have de-facto authorization? Presumably, Administration has specific requirements about how the DIP is formed in order for it to be able to update/migrate it and re-submit it to ingest. Where are these requirements specified?
