Check a course package before it goes to your LMS

Drop the published .zip — SCORM 1.2, SCORM 2004, cmi5, xAPI or AICC. You get a plain list of what will break and how to fix it: missing or mis-cased files, a zipped folder, Flash, resume data too big for SCORM 1.2, and more. Your file is uploaded for checking only and deleted immediately; never kept.

What the checker looks at

It reads the package the way an LMS will — manifest first, then every file it names — without running any of the course's code. Each finding says what learners would see, how to fix it, and the specification rule or LMS behavior behind it.

Package structure

  • imsmanifest.xml at the root of the zip — or found one folder down, the classic zipped-the-folder mistake
  • Well-formed XML and the declared SCORM version (1.2, or 2004 2nd, 3rd or 4th Edition)
  • Default organization, every item's resource, unique identifiers
  • Every launch file and listed file present, including names that differ only in upper/lower case
  • No local file paths or off-site launch URLs; mastery scores, completion thresholds and sequencing

Runtime risk

  • Code that finds the LMS API and closes the session
  • SCORM 1.2's 4,096-character resume-data limit, judged against the authoring tool and course size
  • Storyline launched without index_lms.html; Flash content; http:// media inside an https LMS
  • Very large packages and media files; file names that break web addresses
  • Known LMS behaviors: a session opened before the course, and an empty entry value on resume

cmi5, xAPI and AICC

  • cmi5.xml: AU ids are IRIs, launch URLs resolve, launchMethod and moveOn are valid
  • tincan.xml: an activity with a launch file, an IRI id that is not a placeholder
  • AICC: all four course structure files and a launch file that exists

Facts at a glance

  • The package checker reads the manifest and every file it names without running the course's code, so runtime findings are flagged as risks, not proofs.
  • It catches a manifest one folder down — the result of zipping the folder instead of its contents — which most LMSs reject.
  • It flags launch and listed files whose names differ only in upper/lower case: they work on Windows and macOS and fail on Linux LMS servers.
  • SCORM 1.2 guarantees 4,096 characters of resume data (cmi.suspend_data); the checker warns when a Storyline course published as SCORM 1.2 is large enough to risk it, and SCORM 2004 3rd Edition raises the limit to 64,000.
  • cmi5 and xAPI packages are checked for IRI activity ids and launch files that exist; AICC packages for all four course structure files.
