 #### 6.3.1.1 Communication direction OGC/STA Server towards IPE
 
 In Figure 6.3.1.1-1, an OGC/STA client is connected to an OGC/STA server, and its data is forwarded to the IPE. The OGC/STA client publishes data to the OGC/STA server via an HTTP-POST message. The 'result' attribute of an "Observation" contains the sensor data.
-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".
