-Figure 6.2-2 shows the OGC/STA-to-oneM2M direction. The IPE subscribes to the desired "Datastream" of the MQTT-Broker at the OGC/STA server. The OGC/STA server publishes a new "Observation" via the MQTT broker triggert by a OGC/STA sensor. The IPE creates a `<contentInstance>` in a container, to be created as detailed in Section 6.3.2 in the CSE and copies the 'result' attribute of the "Observation" to the 'content' attribute of the `<contentInstance>`. The oneM2M applcation gets the sensor data either by polling the CSE or subscribing to the desired `<container>` at the CSE.
