What is xAPI (Tin Can)?

Experience API (xAPI), also known as Tin Can API, is a learning technology specification that enables the collection of data about a wide range of learning experiences. Developed by Advanced Distributed Learning, xAPI provides a standard method for capturing and sharing learning data between various systems.

Unlike older specifications like SCORM (Sharable Content Object Reference Model) that are limited to tracking online learning in a Learning Management System (LMS), xAPI is capable of recording, storing, and retrieving learning experiences both online and offline across different platforms. This includes experiences such as mobile learning, simulations, virtual reality, social learning, informal learning, and more.

Project Tin Can: The Genesis of xAPI

In the sphere of e-learning, Project Tin Can marked a significant leap forward in the evolution of learning technologies. The brainchild behind Project Tin Can is the Experience API (xAPI), a learning technology specification that has revolutionized the e-learning landscape by broadening the capacity to collect data about a wide range of learning experiences. Here is the story of its creation:

In the late 2000s, the Advanced Distributed Learning initiative recognized the limitations of the existing e-learning standards like SCORM (Sharable Content Object Reference Model) and AICC (Aviation Industry Computer-Based Training Committee). These protocols were confined to tracking online learning activities within a Learning Management System (LMS), thereby offering a restricted view of the learning journey. With the aim to overcome these constraints, ADL launched Project Tin Can in 2010.

The mission of Project Tin Can was to develop a new learning technology standard that could track a wider variety of learning experiences, both online and offline. ADL reached out to the broader e-learning community for their ideas, needs, and requirements in order to develop this new standard. The feedback was overwhelming and illuminating, reinforcing the need for a more flexible and comprehensive standard.

By 2011, Rustici Software, a leading e-learning technology company, was chosen by ADL to conduct research and development for Project Tin Can. Over the next year, Rustici Software worked closely with the learning community, gathering use cases and requirements to develop the new specification.

The result of this collaboration was the Experience API (xAPI), also known as Tin Can API. Released in 2013, xAPI represented a significant advancement in e-learning technology. Unlike previous specifications, xAPI was able to record these diverse learning experiences in a Learning Record Store (LRS), enabling a more comprehensive view of the learning journey.

Since its inception, xAPI has been widely adopted and continues to evolve, with new versions released to address emerging needs in the e-learning industry. The birth of xAPI from Project Tin Can marked a turning point in e-learning, enabling richer, more diverse, and comprehensive learning experiences, truly embodying the ethos of lifelong learning in the 21st century.
