xAPI Course Builder Profile (v1.1)

This xAPI Profile defines the statements sent by every course built with xAPI Course Builder:

• Course progress: opened, started, completed, and each lesson viewed
• cmi5: when a cmi5 package is launched by an LMS, the cmi5 defined statements about the AU (initialized, completed, passed, failed, terminated)
• Questions: true/false, choice, hotspot, drag-and-drop, sequencing and free-text answers, as cmi.interaction activities
• Assessments: scored sections reported as passed or failed against a pass mark
• Feedback: star ratings and comments, following the Feedback Interaction Profile
• Video: playback following the ADL xAPI Video Profile v1.0.3
• Audio: playback following the ADL xAPI Audio Profile v1.0

Identifying statements

Every statement names this profile version as a category context activity. Video and audio statements also name the ADL Video or Audio Profile.

"context": { "contextActivities": { "category": [
{
    "id": "https://xapi.com.au/profiles/course-builder/v1.1",
    "definition": {
        "type": "http://adlnet.gov/expapi/activities/profile"
    }
}
] } }

Each statement matches exactly one template, by its verb and object activity type. Unless a template says otherwise, every statement also:

• has a timestamp, and a context.registration when the course is launched with one;
• carries the course's published version in the version context extension;
• has the course activity as its parent, unless the statement is about the course itself.

Activity ids are built from the course activity id given at launch: …/lesson/{id}, …/section/{id} for assessments, and …/block/{id} for questions, feedback and media.

Patterns

• Course attempt (per registration, xAPI launch): opens with Course initialized, which is sent again on every relaunch, followed by any of the statements above. Course started is sent once, and Course completed once the course's requirements are met.
• cmi5 attempt (per registration, cmi5 launch): one or more sessions, each opening with cmi5 initialized and closing with cmi5 terminated (unless the session was abandoned, which the LMS records). The course's own statements, and cmi5 completed, passed or failed, fall in between. Completed and passed are sent at most once per registration; passed is never followed by failed. Only initialized and terminated are sent in Browse and Review launch modes. cmi5 statements carry the LMS's context template, including its sessionid extension.
• Video session and Audio session (per session-id): initialized, then any of played, paused, seeked, interacted and completed, then exactly one terminated. This is the ADL Video and Audio Profiles' general pattern. Video sends completed once, when 95% has been watched (the completion-threshold extension).

Concepts defined by this profile

• Course version (ContextExtension): https://w3id.org/xapi/course-builder/extensions/version
  The published version label of the course that sent the statement. The player reads it back to decide whether a saved place or assessment result still applies.
• Assessment answers (ResultExtension): https://w3id.org/xapi/course-builder/result-extensions/answers
  On a scored assessment's passed/failed statement: each question block id mapped to whether the learner's first answer was correct.

Per-course profiles

Each exported course package includes its own xapi-profile.jsonld, which contains just the templates and patterns that course's blocks use. Alongside it, xapi-activities.json lists each lesson, assessment and tracked block, with the templates it sends.
