I was referring to systems that are designed to teach people.

SCORM for example.

Scorm is a zip file with html files to structure content any way you want with a minimal amount of mandatory standards.

It was never meant for assessment, nor is it secure. The creator of scorm said to not use it learning had to be secured.

It’s not a system or a framework in any meaningful or standardized sense, and more of a format for compiling content that can be copied between different places.
