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.
