## 6.2 Communication Flow
-Figure 6.2-1 shows the oneM2M-to-OGC/STA direction. In order to transfer data from a oneM2M sensor to the OGC/STA server the IPE creates a `<subscription>` to the `<container>` resource in the CSE containing the desired data. Triggered by a sensor event a new `<contentInstance>` is added to the `<container>` by the `<AE>`. The IPE gets a `<notification>` containing the `<contentInstance>` resource.
-The IPE constructs an "Observation" creation request and copies the 'content' attribute of the `<contentInstance>` to the 'result' attribute of the "Observation" and sends it to a "Datastream" to be created as detailed in Section 6.3.1 at the OGC/STA server. The OGC/STA applcation gets the sensor data either by polling the OGC/STA server or subscribing to the corresponding "Datastream" at the MQTT broker of the OGC/STA server.

### 6.3.0 Introduction
-To enable interworking, preparation is required for both the oneM2M-CSE and the OGC/STA server (see Figure 6.3.0-1). As described in Section 6.0, the IPE maps data from an OGC/STA "Observation" to a oneM2M `<contentInstance>` and vice versa. This specification defines a 1-to-1 relationship in each direction between the "Datastream" associated with the "Observation" and the `<container>` associated with the `<contentInstance>`. An IPE may implement multiple 1-to-1 relationships.

The IPE requires a destination-"Datastream" to send an "Observation" containing data from the oneM2M side. If no associated "Datastream" exists on the OGC/STA server, it shall be created. This can be done beforehand or at the IPE's start-up, depending on the implementation.
When a "Datastream" is created on the OGC/STA server, a reference ID (e.g. {"@iot.id:3635353"}) is returned. This reference is required by the IPE to associate an "Observation" with a "Datastream" and shall be available during IPE operation. In addition to the "Datastream" other entities of the STA Sensing Entities Data Model <a href="#_ref_i.1">[i.1]</a>, such as "Location" or "Sensor," may be created.
-The creation of entities like "Datastream" and "Thing" requires several mandatory properties that shall be known at configuration time (e.g., 'name' and 'description'). These property fields may be automatically derived, for example, from the "Label" or "ResourceName" attributes of the corresponding oneM2M `<container>` resource or if existing, from the corresponding `<AE>` resource 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>.

Once the destination-"Datastream" is created, the IPE can send an "Observation" to the OGC/STA server as HTTP POST message. An interested OGC/STA client can subscribe to the destination-"Datastream" at the MQTT Broker of the OGC/STA server to receive each "Observation" forwarded by the IPE (see Figure 6.3.1.2-1). Alternatively, the OGC/STA client may use an HTTP-GET request to retrieve the data as needed.
