Web of Things (WoT) • WoT isa way to realize the IoT. • IoT(Internet of Things): Global infrastructure enabling advanced services by interconnecting Things • WoT(Web ofThings): 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 environment. Web of Things ? = Things <Ref. Framework of the WoT, Rec. ITU-T Y.2063>
Use Case of WoT at Home • Smart Home is one of the most representative use case of WoT. • User’s demands to remotely control & monitor home appliances using mobile devices are increasing.

ITU-T Y.2063: Framework of the WoT • Released at July of 2012 by ITU-T Study Group 13 • Describes the overview, identifies the requirements to support the WoT • Specifies the functional architecture for WoT <Conceptual Model of the WoT, ITU-T Y.2063 >
WoT Functional Architecture of ITU-T Y.2063 • Divided into 3 layers: service, adaption and physical layer • Service layer makes a service available & manage it • Adaption layerinteracts with physical devices for the translation of different protocols and message formats • Physical layer includes physical devices
Needfor HES Application Model of WoT • The WoTmodel of ITU-T Y.2063 is a generic model independent of application domains. • Needs to be rebuilt to be applied to the specific domains considering their environmental 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 WoTservices
Proposal of New Standard • Title • ISO/IEC 15067-x HES application model: Modelof a WoT(Web of Things) System for HES • Scope • This standard specifies a generic high-level model for a WoT system using HESthat 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.
Outline of the Proposed Standard • 1. Introduction • 2. Scope • 3. WoT(Web of Things) for HES • 4. The model of a WoT system for HES • 4.1 WoTsystem taxonomy and lexicon • 4.2 Logical and physical models • 4.3 Taxonomy of WoT system Services • 4.3.1 Structure of Services • 4.3.2 Service1… • 4.3.m Service1 n • 4.4 Lexicon for WoT system • 4.4.1 HES message lexicon overview • 4.4.2 HES message list • Annex A: Appliance Profiles for constraint Web protocols (Informative) • Annex B: Appliance Profiles for HTTP (Informative)
WorkingSchedule • All work will be finished in 36 months. • NWIP with a Working Draft • April 2015 • First CD • Oct. 2015
