Which of the following is a key feature of JSON-LD used in Web of Things (WoT)?
JSON-LD (JSON for Linking Data) extends standard JSON by adding semantic contexts (@context), allowing WoT Thing Descriptions to interoperate seamlessly across disparate semantic web ontologies.
What is the role of a 'WoT Portal' in a Web of Things enterprise deployment?
WoT Portals serve as executive dashboards and developer API portals, combining WoT device management, RESTful API endpoints, and Business Intelligence (BI) analytics.
What safety concern arises when an IIoT actuator (e.g., robotic arm) is controlled over a wireless network?
In IIoT, safety (protecting physical surroundings from harm) and security (protecting software/network from attacks) are deeply connected; network delays in safety-critical control loops can lead to catastrophic industrial failure.
Which cloud computing model allows IoT developers to deploy custom IoT application code without managing the underlying virtual machines or operating systems?
PaaS (and Serverless FaaS like AWS Lambda or Azure IoT Hub) provides managed application runtime environments where IoT developers deploy backend code without worrying about server provisioning.
Which open standard protocol is commonly used for authorization and security access control in WoT REST APIs?
OAuth 2.0 paired with JWT tokens is the de facto web standard for securing RESTful API access in Web of Things architectures, enabling scoped permission tokens for clients.
