### 6.3.0 Introduction
In order to enable interworking, preparation is needed for both the oneM2M-CSE and the OGC/STA server (Figure 6.3.0-1).
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.

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.
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".

The IPE shall subscribe to the "Datastream" containing the observations to be forwarded to the oneM2M side at the MQTT broker of the OGC/STA server using its specific URL or topic, e.g., {sta-example-server-address.com/v1.0/Datastreams(8715)}. Upon successful subscription, the IPE will receive every "Observation" pushed to that "Datastream".
