  • CET needs for repository

    • manages "items" or "documents" = "units"

    • managing metadata at the level of units, not blocks

    • searching for units, not blocks

    • unit has versions

      • editing creates new version

      • usage of unit - use a specific version

      • have business rules around what is manually or automatically propagated

      • as soon as a student enrollment happens, edits are no longer automatically propagated.

    • learning context = learning environment

    • searching for units in depot

      • users search and drag n' drop in courses

      • find unit only once, but select which version

      • currently, each copied version is found - need to group them

        • copy on edit

        • 5% of teachers make changes in HS

          • need to prep students for final exams - so want to personalize for the class or special needs students.

        • search by where it is found

          • topic of unit, description of unit

  • CET Subtrees

    • units are in either categories or trees

    • course can have many levels

    • permissions on units

      • not everyone can open or see.

      • permissions are assigned by the subtree

      • depending on which tree it is located

    • can duplicate subtrees

    • subtrees of 100,000 of units doesn't scale

  • Content tagging - looking at 3rd party solutions

    • IBM Watson content tag - $250 / month

    • Pimcore

  • Common protocol for interchanging content between Open edX and CET's repository

    • OLX
