## 6.2 Communication Schema
In order to transfer data from a oneM2M sensor to OGC/STA the IPE creates a <subscription> to the <container> resource with the desired data and when a new <contentInstance> is added it gets a <notification> message containing the <contentInstance> resource.
Figure 6.2-1 shows the oneM2M-to-OGC/STA direction. Based upon the creation of the <contentInstance> in the hosting CSE, the IPE gets a <notification>> message including the <contentInstance>. The IPE constructs an "Observation" creation request and copies the 'content' attribute of the <contentInstance> to the 'result' attribute of the "Observation" shown in Figure 6.2.2.0-2 and sends it to the OGC/STA server.
