Introducing concept of M2M-application data modeling Group Name: MAS Source: FUJITSU Meeting Date: Agenda Item: Semantics and Device Configuration
Topic Summary The preparation of the data content is responsibility of the field domain entities, but that makes difficult to integrate collected data. oneM2M should provide mechanism to instruct the field domain entities which data is prepared. Proposal of ‘collected data centric model’: – MAS group discussed on modeling device capabilities deeply, but modeling for combined data from multiple device or partial data within device is not covered yet. – ‘collected data’ is the destination of M2M data collection (‘device model’ is the source of it) MAS R01 2
Use Case: IoT Platform HEMS Application Home Automation Application Adaptor + Interests on: Energy Consumption, Switch-Status Interests on: Switch-status, SW-control, Place MAS R01 3
Potential Problem IoT Platform HEMS Application Home Automation Application Adaptor + Interests on: Energy Consumption, Switch-Status Interests on: Switch-status, SW-control, Place May not have remote-control capability May not be compatible with others Could be Propriety Solution MAS R01 4
Assumed use of IoT Platform HEMS Application Home Automation Application Adaptor + Interests on: Energy Consumption, Switch-Status Interests on: Switch-status, SW-control, Place Containers for HEMS Containers for HA They can be separated MAS R01 5

Sensor-1PlatformService App Request to configure Virtual Device (desired data components) Configure Sensor-1 Setting (desired data component-1) CREATE at instructed Sensor-2 Configure Sensor-2 Setting (desired data component-2) CREATE at instructed Combine data containers into single data at Access to combined as Virtual Device (desired data components) MAS R01 7
Proposals Adding (producing) data modeling in scope of MAS discussion Adding potential requirement regarding ‘data modeling’ MAS R01 8
Potential Requirements M2M Platform shall be able to collect data from M2M Device, with specifying desired data components. M2M Devices shall be able to provide available data components. MAS R01 9
