IEEE/Std/1484.12.1-2020 Learner Object Metadata 2.0

• IEEE Standard for Learning Object Metadata (1484.12.1-2020)

  • IEEE Xplore
  • EdTech/Wiki/Learning/Object/Metadata

  • 📖 Overview

    • A standard that defines metadata structure for describing learning objects
    • Enables interoperability and discovery of learning resources across systems
    • Part of US/Gov/ADL/TLA's core standards for content description

  • 🎯 Purpose

    • Facilitate search, evaluation, acquisition, and use of learning objects by:
      • Learners
      • Instructors
      • Automated software processes
    • Enable sharing and exchange of learning objects through:
      • Development of catalogs and inventories
      • Support for diverse cultural and linguistic contexts
    • Ensure semantic interoperability between different LOM implementations

  • 📋 Scope

    • Defines metadata structure for learning objects where:
      • Learning object = any entity (digital or non-digital) used for learning
      • Metadata instance = description of learning object characteristics
    • Supports linguistic diversity of:
      • Learning objects themselves
      • Their metadata descriptions

  • 🏷️ Metadata Categories

    • Core Categories

  • 💡 Key Concepts

    • Learning Object

      • Any entity (digital or non-digital) used for:
        • Learning
        • Education
        • Training

    • Metadata Instance

      • Describes relevant characteristics of a learning object
      • Enables systems to:
        • Manage learning objects
        • Locate resources
        • Evaluate content
        • Exchange data

  • 🔄 Implementation

    • Standard provides conceptual data schema
    • Actual implementation defined by other standards
    • Designed as base schema that can be extended
    • Enables automated scheduling of learning objects

  • 🌐 Interoperability

    • Supports transformation between different bindings
    • Ensures high degree of semantic interoperability
    • Facilitates cross-platform content sharing
    • Enables multi-language support

  • 📚 Standard Vocabulary

    • Terms from the IEEE Standards Dictionary

    • Category

      • A group of related data elements
      • Used to organize metadata into logical groups

    • Datatype

      • A property of distinct values
      • Defines:
        • Common features of values
        • Operations on those values

    • Extended Data Element

      • Element defined outside the standard
      • Permitted within data structure instance
      • Enables extensibility of the standard

    • LangString

      • Special datatype for character strings
      • Supports multiple equivalent strings:
        • Translations
        • Alternative descriptions
      • Enables multilingual metadata

    • Learning Object

      • Any entity used for learning purposes:
        • Can be digital or non-digital
        • Used in education or training
        • Basic unit of educational content

    • LOM Data Element

      • Standard-defined data element with:
        • Name
        • Explanation
        • Size
        • Ordering
        • Value space
        • Datatype

    • Smallest Permitted Maximum

      • For implementation-defined values
      • Defines minimum constraints
      • Referenced in section 4.5 of standard

    • Value Space

      • Set of values for a given datatype
      • Can be:
        • Explicitly enumerated
        • Defined by reference to other standards
      • Note: Definitions based on ISO/IEC 11404:1996
