The Short Time Historic (STH, aka. Comet) is a component of the FIWARE ecosystem in charge of managing (storing and retrieving) historical raw and aggregated time series information about the evolution in time of context data (i.e., entity attribute values) registered in an Orion Context Broker instance.

All the communications between the STH and the Orion Context Broker as well as between the STH and any third party (typically for data retrieval) use standardized NGSI9 and NGSI10 interfaces.
