scope:

The present document allows application developers to describe the status of devices as resources on oneM2M-based platform in various ways. Thus different application developers can create different resource trees even when they build the same kinds of applications. Moreover when handling the same kinds of devices from different vendors on M2M platforms, application developers may create disunited resource trees without common information model.

In order to solve such issues, the present document intends to provide the common and unified APIs on one M2M platform for the home domain by defining an abstract information model for the home domain devices such as TV, refrigerator, air conditioner, smart meter, and lighting equipment. The definition of the abstract information model will be based on data models that currently exist in the home domain. The home domain abstract information model does not intend to define the interworking function between the oneM2M system and protocols of the data models from which the abstract data model is defined.

Also, the present document intends to define how the developed abstract information model for a device could be represented in the CSEs of the oneM2M system.
