W3C Web of Things (WoT) addresses the IoT fragmentation problem

In traditional Internet of Things (IoT) projects, developers grapple with the complexity of diverse systems and services from different vendors, hindering flexibility and interoperability. Customers want to be able to choose devices from multiple vendors without redesign. The W3C Web of Things (WoT) simplifies IoT application development by offering standardized building blocks. The WoT uses web technology to harmonize access to diverse IoT devices and breaks silo walls. This allows WoT applications to be written on top of a single, portable interaction abstraction.

Many sectors benefit from WoT standards, e.g. smart homes, smart cities, smart industry, smart agriculture, smart healthcare and many more.

New on 5 Dec. 2023: without breaking compatibility with the first release in 2020, W3C published three new WoT Web standards: Architecture 1.1, Thing Description 1.1, and Discovery. These new W3C Recommendations were also revised to improve the usability of the previous release and address new use cases. In addition, two supporting W3C Notes have been updated, the Web of Things (WoT) Binding Templates and the Web of Things (WoT) Scripting API.

Widely adopted and supported

Numerous software packages and open-source projects now support WoT, including tools for Thing Description validation and construction as well as support for Thing runtimes and Thing Description directories supporting discovery.

Market adoption of the WoT is gaining momentum, with notable products such as SayWoT! and Desigo CC from Siemens.
