Full title and description

ISO/IEC 30118-3:2021 — Information technology — Open Connectivity Foundation (OCF) Specification — Part 3: Bridging specification. This international standard specifies a framework and generic requirements for translation (bridging) between OCF devices and non‑OCF ecosystems, and the behaviour of a Bridging Function that exposes servers across ecosystems.

Abstract

This document defines the bridging framework used to translate resources and interactions between OCF and other IoT ecosystems. It describes generic bridge platform requirements, resource discovery, symmetric and asymmetric bridging modes, considerations for "deep translation" versus "on‑the‑fly" translation, and security considerations; device and resource type definitions are included. Translation rules for specific device types are left to other documents.

Scope

Defines a generic bridging framework and normative behaviour for a Bridging Function that enables interoperability between OCF Clients/Servers and components in non‑OCF ecosystems. Covers discovery, representation and translation approaches, bridge platform requirements (including symmetric and asymmetric models), and baseline security considerations; detailed per‑device translation (deep translation) is out of scope and handled by other, more specific documents.

Key topics and requirements

• Framework for translation between OCF and non‑OCF ecosystems (bridging architecture).
• Behaviour and functional requirements for a Bridging Function (exposing servers/clients across ecosystems).
• Support for symmetric and asymmetric bridging models and platform‑level requirements.
• Resource discovery mechanisms and mapping of resource types.
• Guidance on "deep translation" (per‑device) vs. on‑the‑fly translation.
• Baseline security considerations affecting bridging operations.
• Device and resource type definitions to support consistent mapping.

Typical use and users

Used by IoT platform architects, device manufacturers, firmware and middleware developers, system integrators, and test/QA teams who need to implement or verify interoperability between OCF‑compliant devices and other ecosystems. Also referenced by standards committees and product managers specifying cross‑ecosystem integration requirements.

Related standards

Part of the ISO/IEC 30118 series of OCF specifications (examples include ISO/IEC 30118‑1 Core specification, ISO/IEC 30118‑2 Security specification, ISO/IEC 30118‑4 Resource types, ISO/IEC 30118‑5 Device specification and other parts addressing cloud and profile extensions). These companion parts provide core architecture, security, device and resource definitions that complement the bridging specification.

FAQ

Q: What is this standard?

A: ISO/IEC 30118‑3:2021 is the OCF Bridging specification — the part of the ISO/IEC 30118 series that defines how to translate and expose resources between OCF and non‑OCF ecosystems (Bridging Function behaviour and generic bridging framework).

Q: What does it cover?

A: It covers the generic framework and requirements for bridge platforms, resource discovery and mapping, symmetric/asymmetric bridging modes, guidance on translation approaches (deep vs on‑the‑fly), and security considerations; it does not provide exhaustive per‑device translation rules.

Q: Who typically uses it?

A: IoT device and platform implementers, integrators and test teams who need to enable or validate interoperability between OCF devices and other ecosystems, plus standards bodies and product architects.

Q: Is it current or superseded?

A: The document is the second edition published in October 2021; it replaces the earlier 2018 edition (ISO/IEC 30118‑3:2018) and is listed as the published (current) edition as of 2021.

Q: Is it part of a series?

A: Yes — it is one part of the ISO/IEC 30118 family of OCF specifications (the series includes the Core, Security, Resource Types, Device Specification, Device‑to‑Cloud and other parts). Implementers typically use multiple parts together to achieve full OCF compliance.

Q: What are the key keywords?

A: Bridging, OCF, interoperability, resource discovery, translation, deep translation, bridge platform, symmetric bridging, asymmetric bridging, IoT.
