 ## Overview
 
-The SightingDB format is in JSON [@!RFC8259] format and used to query a SightingDB compatible connector. In SightingDB, a Sighting Object is composed of a single JSON object. This object contains the following fields: value, first_seen, last_seen, count, tags, ttl, frequency and manifold.

-Frequency is the number of time an Attribute is seen in average per day. As this field can introduced latence, its implementation is **OPTIONAL**.
