Full title and description

Information technology — Individualized adaptability and accessibility in e‑learning, education and training — Part 3: "Access for all" digital resource description. This international standard defines a metadata/information model for describing digital learning resources so they can be matched to individual learners' accessibility needs and personal preferences.

Abstract

ISO/IEC 24751-3:2008 provides a common language and information model for describing original and adapted digital learning resources, the access modes by which resources can be used, and metadata elements needed to support matching resources to learners' needs and preferences (as defined in ISO/IEC 24751-2). The standard explains the model, datatypes and occurrences for each element, conformance rules for tools and delivery systems, recommended default values, and mappings to existing AccessForAll/IMS bindings.

General information

Scope

The standard specifies an information model and vocabulary for describing digital learning resources so that learning systems and content repositories can identify and select resources (or adapted variants) appropriate to an individual learner's accessibility needs and personal preferences. It covers the concepts of original versus adapted resources, access modes, adaptability and interoperability, and provides conformance rules and implementation examples for metadata authors, resource providers and delivery systems.

Key topics and requirements

• Information model for AccessForAll digital resource description (attributes, datatypes, allowed occurrences).
• Definitions of original and adapted resources and the relationship between them.
• Specification of access modes for resources (how a resource can be presented or interacted with).
• Rules and guidance for adaptability and for creating adapted resource variants.
• Conformance requirements for metadata authoring tools, resources and education delivery applications.
• Vocabulary codes, default recommended values for preferences/needs, and mappings to IMS AccessForAll metadata (ACCMD) bindings.
• Informative implementation examples and information scenarios to support interoperability.

Typical use and users

Used by learning technologists, LMS and content-authoring tool vendors, content repository managers, accessibility specialists, instructional designers, educational institutions, and standards implementers who need to represent resource accessibility characteristics and support automated matching of content to learner needs.

Related standards

ISO/IEC 24751 is a multi‑part family: Part 1 (framework and reference model) and Part 2 (personal needs and preferences) are direct companions. The standard references IMS AccessForAll metadata (ACCMD) bindings and is commonly considered alongside accessibility guidance such as WCAG and other ISO/IEC accessibility-related work (for example ISO/IEC 24786 and related TRs).

FAQ

Q: What is this standard?

A: ISO/IEC 24751-3:2008 is the part of the ISO/IEC 24751 family that defines a digital resource description model ("Access for all" digital resource description) to support matching learning resources to individual accessibility needs and preferences.

Q: What does it cover?

A: It covers the information model and vocabulary for describing original and adapted digital learning resources, access modes, adaptability concepts, conformance rules, recommended default values, and example bindings (notably IMS AccessForAll/ACCMD).

Q: Who typically uses it?

A: LMS/platform developers, content authors and repositories, accessibility engineers, instructional designers, and organizations implementing personalized accessibility or accommodations in computer-mediated learning.

Q: Is it current or superseded?

A: As published, ISO/IEC 24751-3:2008 is the first edition (2008) and is listed as published and subject to periodic review. Users should verify the ISO catalogue or their national standards body for any amendments or newer versions before adoption.

Q: Is it part of a series?

A: Yes — it is Part 3 of the ISO/IEC 24751 series; Part 1 defines the framework and reference model, and Part 2 defines personal needs and preferences (PNP). The three parts are intended to be used together to enable individualized adaptability and accessibility in e‑learning.

Q: What are the key keywords?

A: Accessibility metadata, AccessForAll, digital resource description, personalization, PNP, IMS ACCMD, e‑learning interoperability.
