Verdict Object

Verdict A Verdict is chosen from all of the Judgements on that Observable which have not yet expired. The highest priority Judgement becomes the active verdict. If there is more than one Judgement with that priority, then Clean disposition has priority over all others, then Malicious disposition, and so on down to Unknown.

The ID of a verdict is a a str of the form "observable.type:observable.value" for example, "ip:1.1.1.1"

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.

Property	Type	Description	Required?
type	ObservableTypeIdentifierString	The type of observable.	✓
value	String	The value of the observable.	✓
