Working of xAPI

To understand how xAPI works, let’s take a closer look at its key components and their interactions:

Learning activities

Learning activities encompass any action or experience that a user engages with as part of their learning. This can include completing an online module, attending a webinar, participating in a virtual reality simulation, or even reading a specific document. These activities generate data that is recorded as statements.

Learning activity providers

Learning activity providers are the systems or tools that generate or deliver learning activities. This can include learning management systems (LMS), simulations software, virtual reality applications, or even offline activities recorded through mobile apps. These providers generate statements that describe the learning activities and the corresponding user interactions.


Statements are the core data elements of xAPI. They represent individual learning experiences and consist of three key components: actor, verb, and object. The actor refers to the user or learner who performed the activity, the verb describes the action taken by the learner, and the object identifies the learning resource or activity being performed. Statements provide a standardized format for recording and sharing learning experiences across different systems.

Learning Record Store (LRS)

The Learning Record Store (LRS) is the centralized database where all the statements are stored. The LRS acts as a repository for xAPI data and facilitates the retrieval and sharing of learning experiences across different platforms and applications. It provides a secure and structured environment for storing and managing learner data, ensuring the privacy and integrity of the information.
