Learn's Caliper Analytics stream emits a GradeEvent to cover the following use cases:
- Student submits an assignment, a group assignment, or a test
- Instructor enters a grade, comments, or feedback
- Any user updates feedback
- Instructor posts a manual grade
- Instructor overrides a grade
- Instructor clears an overridden grade
- Instructor deletes an attempt
GradeEvents are sent in bulk nightly. Here is some of the key data that is associated with these events:
GradeEvent​
group.courseNumber - the course batch_uid (i.e. the ID sent in by LIS or Data Integration)
object.assignable - …/gradableItems/id - the primary key for the content ID
action - Graded
actor.id - contains a unique ID of the user (the ID is known to Bb)
generated.normalScore - score provided
extensions - contains a tag called bb:user.externalId with the batch_uid for the user
