EVENT

An Event is the thing being recorded in the hub: user completed a course, earned a credential, etc.

This design is influenced by the idea of a Learning Record Store in xAPI, but with less complexity.

Field

Type

Notes

EventId

PRG-UUID
(26+128 chars)

(universally unique Identifier)

E:{ProgramId}-{UUID}

The {ProgramId} helps guarantee uniqueness but also to make the IDs more human readable.

Event Ids are assigned by the Learning Hub.

PublisherProgramId

string (25 char)

Descriptive name for the Program that published this event.

PublisherSystemId

string (25 char)

Identifier for the type of system that published this data.

Currently, only the value “LB” is supported, for LearningBuilder.

EventType

string (50 char)

The type of event as reported by the publisherPublisher.

As of 12.4, the only supported value is AI_COMP_SUCCESS, indicating a successfully completed Activity in LearningBuilder.

This will probably change over time as the Hub is extended to support edits and deletes.

See also PublisherEventCategory, below.

PublisherEventId

string (200 char)

The Program’s unique identifier for the source event.

For LearningBuilder this will be something like “AI:1234”, which would be the Activity Instance WFI #1234

PublisherParticipantId

string (200 char)

The Program’s unique identifier for the person, organization, or entity that the event relates to.

Info

Each event contains the ID of the related party in the publisher’s Publisher’s system. It is up to subscribers Subscribers and publishers Publishers to determine how those values should be mapped between their systems.

PublisherEventCategory

JSON object
optional

High level classification of this event, within the publisher’s Publisher’s system.

Code Block
languagejson
{
  "value": "some constant value",
  "label": "some human readable value"
}

The value property should be an ID or code that represents the event type to the publisherPublisher.

The label property is a human readable explanation of that value, at the time of publishing.

The label can change over time, but the value should stay constant.

This data can be used by the subscriber Subscriber to map different types of publisher Publisher data to different import templates. If omitted, subscribers Subscribers will not be able to differentiate between different types of records coming from the publisherPublisher.

See also:

PublisherEventData

JSON blob

The Publisher’s representation of the event data.

Info

The schema of this JSON structure should be shared with the Subscriber(s), so that they know how to translate it into their own representation in their Event Subscriptions.

EventStartUtc

UTC date/time

Non-null date/time the event started. (If only a single date/time is associated with the event, it is stored here).

EventEndUtc

UTC date/time

Nullable date/time that the event ended.

CreatedUtc

UTC date/time

UTC timestamp when this record was created.

EventDateBucket

string

{ProgramId}-LB-YYYYMMDD

Gathers the year, month, and date from the CreatedUtc field.

Identifier used by the LearningHub query that gathers events to process.

EventType vs PublisherEventCategory

...

PublisherEventCategory is a publisher Publisher concept that differentiates different types of events in their system, such as “Course” or “Exam Result”. These are NOT fixed values and will vary by publisherPublisher. (For LearningBuilder publishersPublishers, this will usually be the Activity Type)

Subscribers can subscribe to specific event categories for specific publishersPublishers, with separate mapping templates for each category.

...

Parameter

Description

PublisherProgramId

The Program that owns the Event.

The API Key must have access to this Program.

PublisherSystemId

The type of system that published the event.

This is an arbitrary string provided by the Publisher. Can be used when a Publisher has multiple systems pushing data into the Hub.

EventType

The type of Learning Hub Event this record represents.

For now, the only supported value is “AI_COMP_SUCCESS”

PublisherEventId

A value that uniquely identifies this event in the publisher’s Publisher’s system.

For LearningBuilder publishersPublishers, this will be an “entity-scoped identifier” such as AI:1234, representing Activity Instance 1234.

PublisherParticipantId

Email address or some other piece of information that uniquely identifiers the primary participant within the publisherPublisher's system.

Ideally, this is an email address or some other identifier that is shared with the Subscribers.

PublisherEventCategory

JSON object containing information about the type of Event, according to the source Program’s system.

The value should be some sort of stable identifier with meaning to the publisherPublisher. This value will determine the Template that will be used in the /processEvent endpoint.

The label should be a human readable value that helps explain the event category to subscribersSubscribers.

Code Block
{ value: "ABC123", label: "Online Course" }

PublisherEventData

JSON object representing the Event in the source Program’s system. When calling /processEvents endpoint, this data will be put thru a template and sent to learningBuilder.

EventStartUtc

The UTC date/time when this Event occurred, or the time that the Event started.

EventEndUtc

The UTC date/time when this Event ended. For Events with only a single timestamp, rather than a range, set this equal to EventStartUTC.

...

The exact fields and field names in the PublisherEventData node will be determined as part of the implementation process, as these are determined by the LearningBuilder instance configuration and that data the publisher Publisher is providing to the LearningHub.
