The LTI upload form only shows the required and recommended metadata fields
This allows you to setup a simple upload form with minimal fields.
All metadata fields are available in LTI search. The visible fields will be populated by default. However with the "show hidden attributes" checkbox the instructor can use the full search scope.
Special LTI fields
Every time someone uploads a video via LTI the following (default hidden) metadata fields are populated.
These fields can be convenient for sanitizing the system.
