ISO/IEC 30118-9:2021(E)
Introduction

This document, and all the other parts associated with this document, were developed in response to

worldwide demand for smart home focused Internet of Things (IoT) devices, such as appliances, door

locks, security cameras, sensors, and actuators; these to be modelled and securely controlled, locally

and remotely, over an IP network.

While some inter-device communication existed, no universal language had been developed for the

IoT. Device makers instead had to choose between disparate frameworks, limiting their market share,

or developing across multiple ecosystems, increasing their costs. The burden then falls on end users

to determine whether the products they want are compatible with the ecosystem they bought into, or

find ways to integrate their devices into their network, and try to solve interoperability issues on their

own.

In addition to the smart home, IoT deployments in commercial environments are hampered by a lack

of security. This issue can be avoided by having a secure IoT communication framework, which this

standard solves.

The goal of these documents is then to connect the next 25 billion devices for the IoT, providing secure

and reliable device discovery and connectivity across multiple OSs and platforms. There are multiple

proposals and forums driving different approaches, but no single solution addresses th e majority of

key requirements. This document and the associated parts enable industry consolidation around a

common, secure, interoperable approach.

ISO/IEC 30118 consists of eighteen parts, under the general title Information technology — Open

Connectivity Foundation (OCF) Specification. The parts fall into logical groupings as described herein:

– Core framework
– Part 1: Core Specification

1 Scope
The OCF Core specifications are divided into a series of documents:

– Core specification: The Core specification document specifies the Fram ework, i.e., the OCF core

architecture, interfaces, protocols and services to enable OCF profiles implementation for Internet

of Things (IoT) usages and ecosystems. This document is mandatory for all Devices to implement.

– Core optional specification (this document): The Core optional specification document specifies the

Framework, i.e., the OCF core architecture, interfaces, protocols and services to enable OCF

profiles implementation for Internet of Things (IoT) usages and ecosystems that can optionally be

implemented by any Device.

– Core extension specification(s): The Core extension specification(s) document(s) specifies optional

OCF Core functionality that are significant in scope (e.g., Wi-Fi easy setup, Cloud).

4 Document conventions and organization
4.1 Conventions

In this document a number of terms, conditions, mechanisms, sequences, parameters, events, states,

or similar terms are printed with the first letter of each word in uppercase and the rest lowercase (e.g.,

Network Architecture). Any lowercase uses of these words have the normal technical English meaning.

In this document, to be consistent with the IETF usages for RESTful operations, the RESTful operation

words CRUDN, CREATE, RETRIVE, UPDATE, DELETE, and NOTIFY will have all letters capitalized.

Any lowercase uses of these words have the normal technical English meaning.
4.2 Notation

In this document, features are described as required, recommended, allowed or DEPRECATED as

follows:
Required (or shall or mandatory)(M).

– These basic features shall be implemented to comply with Core Architecture. The phrases "shall

not", and "PROHIBITED" indicate behaviour that is prohibited, i.e. that if performed means the

implementation is not in compliance.
Recommended (or should)(S).

– These features add functionality supported by Core Architecture and should be implemented.

Recommended features take advantage of the capabilities Core Architecture, usually without

imposing major increase of complexity. Notice that for compliance testing, if a recommended

feature is implemented, it shall meet the specified requirements to be in compliance with these

guidelines. Some recommended features could become requirements in the future. The phrase

"should not" indicates behaviour that is permitted but not recommended.
Allowed (may or allowed)(O).

– These features are neither required nor recommended by Core Architecture, but if the feature is

implemented, it shall meet the specified requirements to be in compliance with these guidelines.

DEPRECATED.

– Although these features are still described in this document, they should not be implemented except

for backward compatibility. The occurrence of a deprecated feature during operation of an

implementation compliant with the current documenthas no effect on the implementation’s

operation and does not produce any error conditions. Backward compatibility may require that a

feature is implemented and functions as specified but it shall never be used by implementations

compliant with this document.
Conditionally allowed (CA).

– The definition or behaviour depends on a condition. If the specified condition is met, then the

definition or behaviour is allowed, otherwise it is not allowed.
Conditionally required (CR).

– The definition or behaviour depends on a condition. If the specified condition is met, then the

definition or behaviour is required. Otherwise the definition or behaviour is allowed as default

unless specifically defined as not allowed.

ISO/IEC 30118-9:2021(E)
Strings that are to be taken literally are enclosed in "double quotes".
Words that are emphasized are printed in italic.

In all of the Property and Resource definition tables that are included throughout this document the

"Mandatory" column indicates that the item detailed is mandatory to implement; the mandating of

inclusion of the item in a Resource Payload associated with a CRUDN action is dependent on the

applicable schema for that action.
4.3 Data types

Resources are defined using data types derived from JSON values as defined in clause 4.3 in

ISO/IEC 30118-1.
5 Functional interactions
5.1 Introduction

The functional interactions between a Client and a Server are described in 5.2 through 5.7 respectively.

The functional interactions use CRUDN messages (clause 8 in ISO/IEC 30118-1) and include

Discovery, Notification, and Device management. These functions require support of core defined

5.3 Device management
5.3.1 Overview
Device management includes the following functions:
– Diagnostics and maintenance
– Network monitoring
5.3.2 Diagnostics and maintenance Resource Type

The Diagnostics and Maintenance Resource Type is intended to enable the resolution of issues

encountered with the Devices while operating in the field. If diagnostics and maintenance is supported

by a Device, the Core Resource "/oic/mnt" shall be supported as described in Table 5.

When reading this Property,
a value of true indicates a
pending factory reset. Once
the factory reset has been
completed, the Device shall
set the value back to false.
This Property is functionally
equivalent to a transition to
a state of Hard Reset as
defined in ISO/IEC 30118-2,
clause 8.1
Reboot "rb" "boolean" N/A N/A R, W No When writing to this

All HTTP errors outside the
100, 200 or 300 range shall
be stored.

NOTE Default indicates the value of this Property as soon as the Device is rebooted or factory reset.

5.3.3 Core behaviours on Device maintenance state changes
5.3.3.1 Overview

As defined in ISO/IEC 30118-2 a Device has a state machine through which it transitions during its

operational lifetime.

ISO/IEC 30118-2 details actions on such state transitions for the Resources defined therein. This

clause defines the actions to be taken on such state transitions for the Resources and functionality

defined within this document.
The state transitions to be considered are:
– RFNOP to Soft Reset
– RFNOP to Hard Reset
– RFNOP to RFPRO
– RFPRO to RFNOP

Table 7 provides a summary of the actions to be taken in each case for functions defined in the

ISO/IEC 30118-2 and this document, other extensions to these documents may define further

behaviours.

5.3.3.2 Handling of Observe transactions

On a transition to hard reset all active Observe transactions shall be cancelled by the Server by sending

a "Service Unavailable" response on each active Observe transaction.

On a state transition that allows for modification of the access controls that exist against a Resource

(such as from RFPRO to RFNOP) it is possible that the access controls themselves as defined within

the ISO/IEC 30118-2 are changed such that the original RETRIEVE operation that established the

Observe would not have been allowed. In such instances the Server s hall cancel the Observe by

sending a "Service Unavailable" response on the Observe transaction.
5.3.3.3 Reset of Resource Properties to defined defaults
5.3.3.3.1 Overview

On a hard or factory reset Resource Properties are reset to default values. These are commonly

referred to as manufacturer defaults however it is not possible in all instances to revert to such values

as they may not be known or be practicable.

The default values to be applied for the mandatory and optional Core Resources, plus any Vertical

Resources are defined in clauses 5.3.3.3.2 through 5.3.3.3.4 respectively.
5.3.3.3.2 Defaults for Vertical Resources

Default values for any Vertical Resources exposed by a Device are up to the implementation.

5.3.3.3.3 Defaults for mandatory Core Resurces

Table 8 and Table 9 capture default values that shall be set for mandatory Properties of the mandatory

Core Resources where those Resources contain Properties that can be changed by a Client. This

excludes "/oic/res" as that has no mutable Properties.
