US/Gov/ADL/TLA

• Total Learning Architecture (TLA)

  • A research and development project by US/Gov/ADL to create an integrated learning services environment
  • Official Project Page

  • 🎯 Core Purpose

    • Enable personalized, data-driven, technology-enabled lifelong learning across:
      • Department of Defense
      • Other Federal Government agencies
      • Beyond government sectors
    • Create a "continuum of learning" that is:
      • Continuous (career-long vs episodic)
      • Blended (formal + informal)
      • Enterprise-focused
      • Learner-centric
      • Data-driven
      • Competency-based
      • On-demand
      • Cloud-based

  • 🏗️ Architecture Components

    • Data Standards

      • Built on key IEEE specifications:
        • IEEE/Std/P9274.1 Experience API xAPI 2.0 for activity tracking
          • Includes xAPI Profiles like cmi5
          • Features TLA's Master Object Model (MOM)
        • IEEE/Std/1484.12.1-2020 Learner Object Metadata 2.0 for content description
        • IEEE/Std/1484.20.3 Sharable Competency Definitions for competency frameworks
        • IEEE/Std/P2997 Enterprise Learning Record for learner profiles

    • Key Projects

      • Competency and Skills System (CaSS)

        • Manages competency frameworks
        • Creates sharable learner profiles
        • Integrates with existing LMSs

      • Data Analytics and Visualizations (DAVE)

        • Provides analysis and visualization tools

      • DATASIM

        • Open-source testing tool
        • Generates datasets for TLA validation
        • Helps evaluate xAPI implementations

      • Privacy Support (PS4TLA)

        • Implements user-tailored privacy
        • Creates personalized privacy models

      • FLUENT

        • Adaptive recommendation system
        • Analyzes xAPI data for learning patterns
        • Identifies effective learning sequences
