Assignable Events

Blackboard Learn’s Caliper Analytics stream emits an AssignableEvent in four cases:

A student starts an assignment
A student submits an assignment
A student starts a group assignment
A student submits a group assignment

Here is some of the key data that is associated with these events:

AssignableEvent - Assignment

group.courseNumber - the course batch_uid (i.e. the ID sent in by LIS or Data Integration)

object.@id - …/gradableItems/id - the primary key for the content ID

action - Started, Submitted, Completed

AssignableEvent - Group Assignment

group.courseNumber - the course batch_uid (i.e. the ID sent in by LIS or Data Integration)

object.@id - …/gradableItems/id - the primary key for the content ID

extensions.bb:group.users - an array of users in the group. The batchUId field will contain the batch_uid for the user

action - Started, Submitted, Completed

For a completed group assignment, the course information is located one level lower in group.subOrganizationOf
