W3C Web of Things
The Web of Things (WoT) counters IoT fragmentation by extending proven Web standards. Through standardized metadata and reusable building blocks, W3C WoT enables seamless integration across IoT platforms and application domains.
WoT in a Nutshell
In typical IoT projects, developers face a fragmented landscape of proprietary systems, incompatible communication protocols, differing data models, and varying security requirements. Applications built this way demand high effort for narrow use cases and become difficult to extend, maintain, or reuse over time.
WoT provides standardized building blocks that simplify IoT application development by applying the well-established Web paradigm. This approach boosts flexibility and interoperability—especially for cross-domain scenarios—while enabling reuse of proven standards and tooling. WoT unlocks the commercial potential held back by IoT fragmentation.
