Observable Object

Observable A simple, atomic value which has a consistent identity, and is stable enough to be attributed an intent or nature. This is the classic 'indicator' which might appear in a data feed of bad IPs, or bad Domains. These do not exist as objects within the CTIA storage model, so you never create an observable.
