A description of the description as metadata used both for interoperability and presentability purposes.A wide variety of existing protocols for accessing the devices.Uniform Resource Identifier (URI) for identifying devices and their descriptions.It presents a set of architectural and programming patterns for building interoperable devices based on the following three fundamentals: WoT is not a proposition for a new communication protocol between devices, it uses existing protocols to communicate with the devices according to their communication capabilities. That resource can then be accessed from a browser or another device in the same manner as a web page. The main idea behind WoT is exposing virtual or physical devices as a resource with a description of its capabilities. WoT is an initiative by the W3C to apply on the IoT device the same principles as for the existing web resources across the Internet. WoT offers an approach to expose and consume IoT resources as web resources. This creates interoperability challenges for communication between devices. Several technologies can be used to build an IoT application mainly because of the specific constraints of the devices.

This document aims to introduce the Web of Things (WoT) as building blocks for applications based on the IoT devices.Īs a growing area, IoT services and application have a huge potential.įrom home automation to smart-grid passing by industrial manufacturers, IoT is gaining popularity as a potential solution to address their need.
