The items an obelisk needs are not even persistant for individual players. its either bugged, or an obelisk is assigned random data when it becomes active. I took notes of all data readings to see what each one wanted in solo, relogged(as they were not reactivating) then went to use the items I had taken note of, and they were all different again.
I still think the sound they emit is the clue to what it needs. Just hard to test when they deactivate after a scan.
