3. Introduction Motivation Core contributors in this topic
oneM2M system provides common service functions that can be utilized by multiple domains including home domain. However, application developers can use these functions differently and have multiple choices to describe the status of devices as resources on oneM2M platform, which does not guarantee cross-vendor interoperability. Defining common abstract information model is thus highly vital to resolve such an issue. Moreover, it would facilitate machine-to-machine interaction without human’s interaction. oneM2M started creating the information model for home domain first.

History of HAIM in oneM2M
`14.09, TP13
`15.03, TP16
`15.09, TP19
`16.05, TP23
`16.07, TP24
A new WI for Home Domain Enablement was created with a study on use cases, necessary technologies (TR-0013)
TS-0023 was finalized for Release 2 including 13 devices and 41 module classes
Reached on a consensus that HAIM is necessary and a new research was started to figure out how to define the information models (TR-0017)
Principle of designing the models was agreed to apply HGI SDT1) and created a new normative technical specification (TS-0023) to specify HAIM
Clean-up, protocol definition were complete. TS-0023 is included in the set of oneM2M Release 2 publication
`16.08 ~
Further home appliance information models would be added and a research on interworking with external information models that are being developed out side of oneM2M such as OCF and AllJoyn would be conducted
1) Home Gateway Initiative SmartHome Device Template

4. Design principle of HAIM in oneM2M
Using Smart Device Template (SDT) as template of oneM2M HAIM
The SDT is an initiative from the Home Gateway Initiative (HGI) to find consensus amongst various SDOs and industry alliance to derive a common approach for device modelling
oneM2M designed the principle of the HAIM based on HGI SDT 3.0 since it’s already well-generalized, expandable and efficient to reduce fragmentation among several technologies
Available at , example models from other consortia include DECT ULE, ECHONET Lite, (s.
SDT Structure
Modularity for functions and device types
Specification of a single service with one or more service(s). This can be re-used in many device definitions
Unique name that acts like a namespace
Arbitrary sequences of operations/methods
Physical appliance/sensor
Variable to be read/written
Async signaling of stage change
A device embedded in a device
Instantiation of a ModuleClass
Arbitrary additional information
