WotThings is built on the W3C WoT Architecture and Thing Description standards
Structured JSON-LD documents describing a Thing's properties, actions, and events — standardized by W3C for universal IoT interoperability.
Reusable templates that define common capabilities across device categories. Build once, instantiate many — reducing duplication in IoT deployments.
Every Thing Description is a JSON-LD document with semantic annotations. Things can reference each other, forming a web of connected devices.
TDs include security definitions (OAuth2, API Key, Basic) so consumers know exactly how to authenticate before connecting to a Thing.
Each interaction (property, action, event) declares its protocol binding via forms — HTTP, MQTT, CoAP, Modbus, or any protocol.
The WoT Directory serves as a searchable registry. Find Things by type, category, or capability — enabling truly dynamic IoT orchestration.
