Full title and description

Information technology for learning, education and training — Language accessibility and human interface equivalencies (HIEs) in e-learning applications — Part 1: Framework and reference model for semantic interoperability. This part defines principles, rules and metadata for specifying language accessibility and human interface equivalents to support interoperable, accessible e‑learning content and systems.

Abstract

ISO/IEC 20016-1:2014 provides a framework and reference model to enable semantic interoperability of language-accessible e‑learning resources by specifying metadata elements, rules and conventions for Human Interface Equivalents (HIEs). The standard is structured to support jurisdictional accessibility requirements, including those arising from the UN Convention on the Rights of Persons with Disabilities (CRPD).

General information

• Status: Published (international standard; under periodic review).
• Publication date: February 2014 (2014-02).
• Publisher: ISO (joint ISO/IEC standard produced under ISO/IEC JTC 1).
• ICS / categories: 03.100.30; 35.240.90.
• Edition / version: Edition 1 (2014).
• Number of pages: 212 pages.

Scope

The standard establishes a framework and reference model for describing and exchanging metadata that represent language accessibility and human interface equivalents in learning, education and training (LET) applications. It addresses how content providers and LET system developers can document, package and make available equivalent human interfaces (for example alternative language renditions, captions, audio descriptions, symbol sets or other interface elements) so that e‑learning resources can be discovered and presented in ways that meet individual accessibility needs. The model is intended to be adaptable to jurisdictional requirements (including UN CRPD obligations).

Key topics and requirements

• Concepts and terminology for language accessibility and Human Interface Equivalents (HIEs) in e‑learning.
• Metadata elements and rules for describing accessibility features and HIEs tied to recorded information (learning resources).
• Reference model to support semantic interoperability between content providers, repositories and learning systems.
• Guidance for mapping jurisdictional accessibility obligations (e.g., CRPD-related requirements) into metadata and HIE provision.
• Implementation considerations for content packaging, discovery and delivery in Learning Management Systems (LMS) and other LET platforms.

Typical use and users

Typical users include e‑learning content authors, LMS and educational platform vendors, accessibility officers and policymakers, digital repository designers, and standards implementers working on semantic interoperability and accessibility in education and training. The standard is mainly used when specifying metadata and delivery mechanisms that ensure accessible equivalents (e.g., translations, captions, symbol sets) accompany learning resources.

Related standards

ISO/IEC 20016-1 sits alongside several accessibility and LET standards that are commonly referenced when implementing accessible learning systems, including ISO/IEC 40500 (WCAG / web content accessibility guidelines), the ISO/IEC TS 20071 series (user interface component accessibility), ISO/IEC 19788 (metadata for learning resources / MLR), and other parts of the ISO/IEC 20000–21999 range covering learning technology and competency models. These provide complementary guidance for content accessibility, UI components and metadata interchange.

FAQ

Q: What is this standard?

A: ISO/IEC 20016-1:2014 is an international standard defining a framework and reference model for language accessibility and human interface equivalencies (HIEs) in e‑learning applications, including the metadata needed to describe such equivalents.

Q: What does it cover?

A: It covers principles, terminology, metadata elements and rules to specify language accessibility features and HIEs so that learning resources can be made discoverable and presented in accessible forms across systems. It also explains how to align those metadata and HIEs with jurisdictional accessibility requirements.

Q: Who typically uses it?

A: Content authors, LMS/platform developers, digital repository managers, accessibility specialists and standards implementers in the learning, education and training sector use the standard to ensure accessible delivery and semantic interoperability of learning resources.

Q: Is it current or superseded?

A: ISO/IEC 20016-1:2014 was published in February 2014 and — per the ISO catalogue — was last reviewed and confirmed in 2025, so the 2014 edition remains current pending any future revision. The ISO record also shows work items related to a follow-up revision (CD 20016-1.2). Users should check the ISO catalogue or national body notices for any updates.

Q: Is it part of a series?

A: Yes — it is Part 1 of the ISO/IEC 20016 series addressing language accessibility and human interface equivalencies in LET applications; other related LET and accessibility standards (e.g., parts in ISO/IEC 20006, ISO/IEC 19788, ISO/IEC 20071) are commonly considered alongside it.

Q: What are the key keywords?

A: Key keywords are language accessibility, human interface equivalents (HIE), semantic interoperability, metadata, e‑learning, accessibility, UN CRPD, LMS, SC36.
