cmi5/Assignable Unit

• 🧩 cmi5 Assignable Unit (AU)

  • An AU is a discrete, launchable learning object—like a lesson, module, video, or simulation—that is:
    • assigned to a learner,
    • launched by the LMS,
    • and reports results using xAPI.
  • Think of an AU like a SCORM/SCO, but designed to be:
    • More modern (works outside the browser),
    • Secure (uses xAPI tokens),
    • And decoupled from LMS constraints.

  • 🧱 Structure

    • In a typical cmi5 course:
      • The course has a manifest (cmi5.xml)
      • That manifest lists one or more AUs
      • Each AU includes:
        • A launch URL (or path)
        • Completion rules (moveOn)
        • Optional metadata (e.g., title, mastery score)

  • 🔁 Example

    • If a course has:
      • Module 1: "Intro to Data Privacy" (AU)
      • Module 2: "Case Study: GDPR Compliance" (AU)
    • Each AU can be launched independently, and each reports back learner progress and results via xAPI.

  • Summary

    • AU = the atomic unit of learning in cmi5, launchable and trackable via xAPI.
