 An "Observation" according to STA Sensing Entities Data Model <a href="#_ref_i.1">[i.1]</a> belongs to a "Datastream" (see Figure 5-2). The IPE shall subscribe to the relevant "Datastream" at the MQTT-Broker of the OGC/STA Server using its specific URL or topic like e.g. {"sta-example-server-address.com/v1.0/Datastreams(8715)"}. After subscribing, the IPE receives every "Observation" that is pushed to that "Datastream".

 Once the "Thing" and "Datastream" entities are created, the IPE can send "Observations" to the OGC/STA server as HTTP POST messages. The interested OGC/STA client can then subscribe to the destination "Datastream" at the MQTT Broker of the OGC/STA server and receive every "Observation" forwarded from the IPE (see Figure 6.3.1.2-1). Alternatively, the OGC/STA client may use an HTTP-GET request to pull the data as needed.
