ISO IEC 30118-16-2021 PDF

Full title and description

Information technology — Open Connectivity Foundation (OCF) Specification — Part 16: OCF resource to UPlus mapping specification. This international standard provides detailed mapping information between UPlus (U+) and OCF-defined resources to enable interoperability between UPlus-based systems and OCF-compliant devices and services.

Abstract

This document specifies the property-by-property mappings and equivalencies required to represent OCF Resources within the UPlus (U+) model (and vice versa) so that data, resource descriptions and behaviors can be translated reliably between the two ecosystems. The mappings are intended to support implementers of gateways, bridges and cross-domain integrations.

Scope

The scope of ISO/IEC 30118-16:2021 is to define the mapping rules and detailed correspondences between UPlus (U+) data/resource models and the Open Connectivity Foundation (OCF) resource model. It identifies equivalent resources, properties, and semantics to allow programmatic translation and interoperability across systems that use either model. The standard focuses on structural and semantic mapping required for gateways, protocol-bridging components and integrators rather than prescribing network transport specifics.

Key topics and requirements

• Definition of equivalencies between UPlus entities and OCF Resources, including device types and resource identifiers.
• Property-by-property mapping rules (how individual resource properties map, transform, or translate between models).
• Use of OCF extensions to JSON schema where required to express mappings and constraints.
• Guidance for implementers on mandatory vs optional mappings and interoperability considerations.
• References to related parts of the ISO/IEC 30118 series (core, security, bridging and other mapping parts).

Typical use and users

Primary users are IoT implementers, platform and gateway developers, systems integrators, device manufacturers and standards bodies working to enable interoperability between OCF-compliant devices and platforms that adopt the UPlus data model. Typical applications include protocol bridging, multi-vendor smart home and industrial IoT integrations, and vendor-neutral device management layers.

Related standards

ISO/IEC 30118 is a multipart suite; related parts include the core specification (Part 1), security (Part 2), bridging (Part 3) and other interface/mapping parts (for example Part 6: Resource to AllJoyn interface mapping). Implementers should consult the other parts of ISO/IEC 30118 for end-to-end interoperability and security guidance.

FAQ

Q: What is this standard?

A: ISO/IEC 30118-16:2021 is Part 16 of the ISO/IEC 30118 series and specifies the mapping between OCF Resources and the UPlus (U+) model to enable interoperable translations between those two models.

Q: What does it cover?

A: It covers detailed mapping rules and equivalencies—property-level mappings, resource-type correspondences, and guidance for implementers to translate resource descriptions and data between OCF and UPlus. It is focused on semantic and structural mappings rather than transport-layer protocols.

Q: Who typically uses it?

A: IoT platform developers, gateway and bridge implementers, device manufacturers integrating OCF devices with UPlus-based services, and systems integrators responsible for multi-vendor deployments. Standards developers and testing labs may also use it for conformance and interoperability testing.

Q: Is it current or superseded?

A: As of its publication it is an active published international standard (Edition 1, published October 2021). Users should check national or ISO/IEC catalogues for any amendments or newer editions before adoption.

Q: Is it part of a series?

A: Yes — it is one part of the multipart ISO/IEC 30118 series (Information technology — Open Connectivity Foundation (OCF) Specification). Related parts address the core specification, security, bridging and mappings to other frameworks.

Q: What are the key keywords?

A: OCF, UPlus, mapping, resource mapping, JSON schema, interoperability, IoT, gateway.
