WoT is a way to realize the IoT.• IoT(Internet of Things): Global infrastructure enabling advanced services by

interconnecting Things

• WoT(Web of Things): All Things connected and controlled through the Web Physical devices can be accessed as resources of the web and services/

applications can be provided based upon a web-based service environ-ment.

Divided into 3 layers: service, adaption and physical layer • Service layer makes a service available & manage it• Adaption layer interacts with physical devices for the translation of different proto-

cols and message formats• Physical layer includes physical devices

Need for HES Application Model of WoTNeed for HES Application Model of WoT

The WoT model of ITU-T Y.2063 is a generic model independent of ap-

plication domains.

Needs to be rebuilt to be applied to the specific domains considering their envi-

ronmental characteristics

A model of WoT system for HES application needs to be defined.

Considers integrating the WoT with the existing HES components and protocols

Defines the functional roles of HES components and their interaction for WoT

services

The application model is essential to guarantee the interoperability

among HES devices for WoT services

Proposal of New Standard

Title

ISO/IEC 15067-x HES application model: Model of a WoT(Web of Things) System for HES

Scope

This standard specifies a generic high-level model for a WoT system using HES that

enables a consumer to control and manage the home appliances inside the house as

well as outside the house using a method known as WoT(Web of Things).

• Develop architectural models specially considering HES

• Specify key services in HES

• Specify communication messages needed to support the services

Purpose and Justification

The models in this standard foster interoperability among WoT products from

competing or complementary manufacturers.
