1. Introducing concept of M2M-application data modeling Group Name: MAS Source: FUJITSU Meeting Date: 2015-07-20 Agenda Item: Semantics and Device Configuration

2. 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-2015-0592R01 2

3. Use Case: IoT @home IoT Platform HEMS Application Home Automation Application Adaptor + Interests on: Energy Consumption, Switch-Status Interests on: Switch-status, SW-control, Place MAS-2015-0592R01 3

4. 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-2015-0592R01 4

5. 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-2015-0592R01 5

6. Retrieve partial data SensorPlatformService App RESISTER (with available data components ) NOTIFY (available data components) Request to configure Device (desired data components [partial]) Configure Device Setting (desired data components) CREATE to store collected data from Device CREATE at instructed Apply setting to produce desired data MAS-2015-0592R01 6

7. Retrieve data from two dev. 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-2015-0592R01 7

8. Proposals Adding (producing) data modeling in scope of MAS discussion Adding potential requirement regarding ‘data modeling’ MAS-2015-0592R01 8

9. 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-2015-0592R01 9
