......@@ -221,9 +221,9 @@ This reference is needed by the IPE to relate an "Observation" to a "Datastream"
The creation of entities like "Datastream" and "Thing" requires a number of mandatory properties that shall be known at configuration time, e.g. 'name' and 'description'. These property fields MAY automatically derived e.g. from the "Label" or "ResourceName" attributes of the regarded oneM2M `<AE>` or `<container>` during IPE configuration. The OGC/STA procedures for creating OGC entities are described in SensorThing API documentation <a href="#_ref_i.1">[i.1]</a>.
When "Thing" and "Datastream" entities are created the IPE is able to send "Observations" to the OGC/STA server as HTTP POST messages. The interested OGC/STA Client can now subscribe to the destination "Datastream" at the MQTT Broker of the OGC/STA server and thus getting every "Observation" forwarded from the IPE (see Figure 6.3.1.2-1)
