Overview
ISO/IEC 30118-17:2021 defines a formal mapping between Open Connectivity Foundation (OCF) resources and Zigbee clusters. The standard documents how Zigbee-defined clusters (Zigbee 3.0 / ZCL) can be exposed, translated and represented as OCF resources, enabling consistent interoperability between Zigbee devices and OCF-based applications, gateways and platforms.
Keywords: ISO/IEC 30118-17:2021, OCF resource to Zigbee cluster mapping, Zigbee to OCF mapping, IoT interworking.
Key topics and technical requirements
The document covers practical mapping rules and technical requirements, including:
-
Mapping theory & approach
- Interworking approach and translation principles for mapping Zigbee clusters to OCF resources.
- Mapping syntax and notation conventions used in the standard.
-
Property and value rules
- Value assignment, property naming, ranges and array handling.
- Default and conditional mappings, and rules for method invocation across protocols.
-
Zigbee translation & gateway requirements
- Operational scenarios for Zigbee bridging functions and specific requirements for Zigbee 3.0 servers.
- Guidelines for exposing Zigbee servers to OCF clients and for creating virtual OCF servers that represent Zigbee devices.
-
Device & resource equivalence
- Device type mapping between Zigbee device types and OCF device types.
- Detailed equivalence tables for common clusters (On/Off, Level Control, Color Control, Thermostat, Window Covering, Temperature Measurement, Occupancy Sensing, IAS Zone, etc.).
-
Detailed mapping APIs
- API-level derived models and property definitions for individual clusters to support consistent implementation and testing.
Applications and who should use this standard
ISO/IEC 30118-17:2021 is targeted at professionals implementing IoT interoperability between Zigbee ecosystems and OCF-based systems:
- Device manufacturers building Zigbee devices that need to interoperate with OCF ecosystems.
- Gateway and hub vendors implementing Zigbee-to-OCF bridging or virtual OCF server functionality.
- IoT platform and application developers who consume OCF resources mapped from Zigbee devices.
- System integrators and solution architects deploying smart home and building automation solutions.
- Test labs and certification bodies validating conformance of mappings and interworking.
Typical use cases include smart lighting, HVAC/thermostat integration, motorized window coverings, environmental sensors, occupancy and security sensor interoperability in unified smart home or building management platforms.
