Full title and description

Information technology — Individualized adaptability and accessibility in e-learning, education and training — Part 2: "Access for all" personal needs and preferences for digital delivery. This part defines an information model and vocabulary for describing individual learner needs and preferences to support matching learners with accessible digital resources and delivery options.

Abstract

ISO/IEC 24751-2:2008 provides a common information model for describing the learner or user needs and preferences when accessing digitally delivered resources or services. It explains the rationale for a functional approach to needs description, methods for producing needs/preference statements, groupings of needs, ranking/prioritization, vocabulary codes and datatypes, conformance considerations for delivery applications and alternative access systems, and informative implementation examples.

General information

• Status: Published (International Standard; listed under systematic review as of ISO record).
• Publication date: October 2008 (2008-10).
• Publisher: International Organization for Standardization / IEC (ISO/IEC JTC 1).
• ICS / categories: 03.100.30; 35.240.90 (Information technology; education/learning technology).
• Edition / version: Edition 1 (2008).
• Number of pages: 95 pages.

Scope

Specifies an information model and set of normative terms, attributes and datatype rules for representing personal needs and preferences for digital delivery in education and training. The standard is intended to be used alongside Part 1 (framework/reference model) to enable matching of learner requirements with appropriate interfaces, resources and delivery mechanisms in computer-mediated learning environments.

Key topics and requirements

• Information model for personal needs and preferences: attributes, allowed occurrences and datatypes.
• Functional approach to describing needs (groupings and prioritization of preferences).
• Vocabulary, codes and recommended default values for accessibility preferences.
• Conformance requirements for education delivery applications and alternative access systems.
• Bindings and mappings to existing learner information packages (for example IMS LIP accessibility bindings) and implementation examples.

Typical use and users

Used by standards authors, LMS and e-learning platform vendors, accessibility tool and assistive-technology developers, instructional designers, educational institutions and procurement teams to represent and exchange learner accessibility needs and to enable automated matching of resources and interfaces to those needs. Implementers use Part 2 to encode personal preference profiles that interact with delivery systems described by Part 1 and resource descriptions in Part 3.

Related standards

ISO/IEC 24751 is a multipart standard. Closely related parts include ISO/IEC 24751-1 (Framework and reference model) and ISO/IEC 24751-3 (Digital resource description). National/adopted variants (for example regional GOST adoption) and IMS accessibility specifications (IMS LIP accessibility bindings) are referenced for interoperability.

FAQ

Q: What is this standard?

A: ISO/IEC 24751-2:2008 is Part 2 of the ISO/IEC 24751 series; it defines an information model and vocabulary for describing personal "access for all" needs and preferences for digital delivery in e-learning, education and training.

Q: What does it cover?

A: It covers how to represent a learner’s accessibility needs and preferences (attributes, datatypes, codes, grouping and prioritization), conformance considerations for systems that provide education delivery and alternative access, and examples/bindings to existing learner information specifications.

Q: Who typically uses it?

A: Implementers and specifiers in the e-learning and educational-technology domain — LMS vendors, accessibility and assistive-technology developers, instructional designers, standards bodies and institutions seeking to support individualized access for learners.

Q: Is it current or superseded?

A: The standard was published in October 2008 (Edition 1). ISO’s record lists it as published and under systematic review (stage 90.20) — users should check their national ISO member body or ISO for the latest review/supersession status.

Q: Is it part of a series?

A: Yes — ISO/IEC 24751 is a multipart standard. Part 1 provides the framework and reference model, Part 2 (this document) covers personal needs and preferences, and Part 3 covers digital resource description.

Q: What are the key keywords?

A: Accessibility, individualized adaptability, learner preferences, e-learning, information model, conformance, IMS LIP.
