Experience API

Experience API is also known as Tin Can API or xAPI.

It is an evolved version of SCORM (Sharable Content Object Reference Model).


The format is quite simple: Noun, verb, object.


  • Activity Provider (AP): responsible to create and track learning experiences;
  • Learning Record Store (LRS): responsible to store the tracking data;
  • Activity: it is the object in the Noun, verb, object protocol. E.g. a book, an e-learning course, a meeting, some real object like a chair in a classroom, etc;
  • Actor: individual or group that does the action;


Verb must be in the past tense, although their display properties may be flexible in tense.
