yeah. to give an example: if I want to store persist objects using localStorage, I'd convert them to JSON and store key-value. However I cannot store whole object hierarchy as it'll soon become an overkill. so I store separate objects, and recreate relations upon retrieval manually. But I also need to maintain my own index - to know which objects I have stored under what keys.
