scope:

The present document specifies the detailed methods for oneM2M and OCF interworking using the architecture identified in oneM2M TS-0033 [5] and annex F of ETSI TS 118 101 [2] for the following scenario:

• Interworking with full mapping of the semantics of the non-oneM2M data model to Mca, see scenario number 1 listed in clause F.2 of ETSI TS 118 101 [2]. This is also in line with the interworking concepts specified in oneM2M TS-0033 [5].

This interworking scenario allows for interworking between OCF devices and oneM2M entities purely based on the common understanding of aligned information models - such as the models defined in ETSI TS 118 123 [6]. There is no limitation regarding the direction of exposure of services: Services provided by OCF devices (OCF servers) can be exposed to oneM2M entities or vice versa. The oneM2M entities do not need to be aware of any details of the OCF protocols or interfaces.
