Concept for systematically describing and using a device's hardware and software capabilities (sensors, actuators, performance characteristics, APIs).
Device Capabilities describes the collection of hardware and software features of an endpoint (sensors, actuators, performance characteristics and APIs) and how they are systematically described and exposed. The concept supports interoperability, adaptability and context-aware functionality across platforms. It is technology-agnostic and architecture-focused.
Proportion of correctly discovered and classified device capabilities.
Average response time for queries to device descriptions or APIs.
Number of integration failures due to inconsistent descriptions per cycle.
A smartphone declares available sensors (GPS, accelerometer) and provides standardized APIs for contextual services.
An edge controller publishes Thing Descriptions to describe actuators and related QoS properties.
A web application checks camera capabilities (resolution, autofocus) and dynamically adjusts capture options.
Inventory existing device properties and APIs
Define a common capability schema (Thing Description or similar)
Implement discovery, mapping and fallback mechanisms
