This Github repository contains the xAPI Specification. xAPI is a learning technologies interoperability specification that describes communication about learner activity and experiences between technologies. The specification is divided into three documents:

Specification versions

The current version of the specification is 1.0.3.

The next version of the specification has not been planned.

What to do if the spec is unclear

If when implementing the specification you find something is unclear or unhelpful, you can help to improve the specification by raising an issue here. When raising an issue, please give as much detail as you can in regards to:

  • Which part/parts of the specification you are reading.
  • Your understanding of what these parts mean.
  • The product and feature you are implementing xAPI in; what's the use case you are trying to achieve?
  • How you would like the specification to be improved. Suggest some specific new wording if you like!

You'll need to sign up for a GitHub account if you do not already have one in order to raise and comment on issues.

You can discuss any issues before or after raising them on the specification Google Group and at our weekly specification calls.
