LPAI permanent identifiers

The identifiers LPAI, the Learning Logbook, defines for the platforms that send it learning activity. They are permanent: once in a statement, an identifier is never reassigned.

Concepts

Identifier	Kind	Meaning
`https://id.learnerrecord.org/xapi/verbs/reacted`	Verb	The learner reacted to the object: result.response is "up", "down" or "favourite". LPAI records an organic reaction signal; a reaction is never evidence of mastery.
`https://id.learnerrecord.org/xapi/verbs/self-checked`	Verb	The learner checked their own understanding (for example "I knew it" on a flip card): result.success true or false, or a scaled score. LPAI records an organic sense-check signal.
`https://id.learnerrecord.org/xapi/extensions/kc-refs`	ActivityExtension	Skills the activity addresses, as the platform knows them: an array of { ref, confidence }. LPAI resolves each reference to its skill graph and records the link as an imported alignment.
`https://id.learnerrecord.org/xapi/extensions/content-version`	ContextExtension	The version of the object the learner actually saw: a content hash or a version label. The key of LPAI's content-to-skill alignment.
`https://id.learnerrecord.org/xapi/extensions/resource-type`	ContextExtension	The kind of resource, when the activity type does not say: one of page, video, audio, document, flip_card, interactive, simulation, assessment_item, assistant, discussion, external_link, other.
`https://id.learnerrecord.org/xapi/extensions/attempt`	ResultExtension	Which attempt at the item this answer is, counting from 1.
`https://id.learnerrecord.org/xapi/extensions/hints-used`	ResultExtension	How many hints the learner opened before answering.
`https://id.learnerrecord.org/xapi/extensions/assistance`	ResultExtension	The help the learner had before answering: none, hint, worked_solution, assistant.
`https://id.learnerrecord.org/xapi/activity-types/page`	ActivityType	A page resource. LPAI records sessions on it with the resource type "page".
`https://id.learnerrecord.org/xapi/activity-types/video`	ActivityType	A video resource. LPAI records sessions on it with the resource type "video".
`https://id.learnerrecord.org/xapi/activity-types/audio`	ActivityType	A audio resource. LPAI records sessions on it with the resource type "audio".
`https://id.learnerrecord.org/xapi/activity-types/document`	ActivityType	A document resource. LPAI records sessions on it with the resource type "document".
`https://id.learnerrecord.org/xapi/activity-types/flip-card`	ActivityType	A flip card resource. LPAI records sessions on it with the resource type "flip_card".
`https://id.learnerrecord.org/xapi/activity-types/interactive`	ActivityType	A interactive resource. LPAI records sessions on it with the resource type "interactive".
`https://id.learnerrecord.org/xapi/activity-types/simulation`	ActivityType	A simulation resource. LPAI records sessions on it with the resource type "simulation".
`https://id.learnerrecord.org/xapi/activity-types/assessment-item`	ActivityType	A assessment item resource. LPAI records sessions on it with the resource type "assessment_item".
`https://id.learnerrecord.org/xapi/activity-types/assistant`	ActivityType	A assistant resource. LPAI records sessions on it with the resource type "assistant".
`https://id.learnerrecord.org/xapi/activity-types/discussion`	ActivityType	A discussion resource. LPAI records sessions on it with the resource type "discussion".
`https://id.learnerrecord.org/xapi/activity-types/external-link`	ActivityType	A external link resource. LPAI records sessions on it with the resource type "external_link".
