Introducing concept of M2M-application data modeling

Group Name: MASSource: FUJITSUMeeting Date: 2015-07-20Agenda 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)

Proposals

• Adding (producing) data modeling in scope of MAS discussion

• Adding potential requirement regarding ‘data modeling’

MAS-2015-0592R01 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.
