BakedIn xAPI Profile v1 (draft)

canonical IRI

Profile identifier

https://bakedin.co/xapi/profile/v1

Statements emitted under this Profile carry it as a category context activity, so a downstream LRS can filter for them bycontextActivities.category[].id.

agent identity

Actor scheme

Pre-authentication, BakedIn issues anonymous per-browser identities as UUIDs persisted in localStorage. Statements identify the learner with the cmi5-styleAgent.account form:

{
  "objectType": "Agent",
  "account": {
    "homePage": "https://bakedin.co",
    "name": "a1b2c3d4-e5f6-4a7b-8c9d-0e1f2a3b4c5d"
  }
}

Once authentication ships (Cognito), the same actor scheme holds — account.name may shift from the anonymous UUID to the authenticated user id, and the anonymous-UUID statements get merged into the authenticated row via a server-side migration.

vocabulary

Verb set

All verbs are ADL-canonical IRIs except where a vocabulary gap forced a fallback. No locally-coined verbs.

profile-specific

Extensions

One profile-specific extension. XP is the BakedIn gamification dimension that doesn’t map to a core xAPI field.

query

LRS endpoint

GET /api/xapi/statements returns BakedIn statements in LRS shape. Filterable by ?agent=<uuid>, ?verb=<iri>, ?activity=<iri>.

Returns up to 500 statements newest-first per request. Not a full xAPI LRS — optimized for “ICICLE Tools-SIG drops in and downloads the BakedIn corpus of statements”.

# Get all completed statements for a specific learner
GET /api/xapi/statements
  ?agent=a1b2c3d4-e5f6-4a7b-8c9d-0e1f2a3b4c5d
  &verb=http://adlnet.gov/expapi/verbs/completed
  &limit=50

scope

What this profile does NOT cover (yet)

Group statements (cohort/teacher constructs — pre-auth)
Voided statements (LRS administrative concern)
Statement signing (cryptographic provenance)
Attachments (rich-media learner submissions)
Substatements (nested LE Process events)

Profile expansion follows IEEE ICICLE Toolkit guidance; tracked in project_icicle_le_strategic.md.
