6.1 OGC/STA-to-oneM2M Data Model Mapping

According to oneM2M TS-0033 [2] a representation of a non-oneM2M Proximal IoT function/device in a oneM2M-specified resource instance is to be synchronized with the entity that it represents. Thus the OGC/STA data model has to be represented in the hosting CSE. The SensorThings data model is comprehensive and should be regarded as a n:m relational database structure, holding both: - sensor (IoT-data); and - administrative data (like historic locations or historic products IDs).

The IPE shall map the 'result' attribute of an OGC/STA 'Observation' to the 'content' attribute of a oneM2M <contentInstance>, and vice versa as shown in Figure 6.1-1.
