The Experience API (also known as xAPI or Tin Can API) is a web service that allows software clients to read and write experiential data in the form of “statement” objects. These statements are stored in a data store called a Learning Record Store, which can exist on its own or within a Learning Management System.
In their simplest form, xAPI statements are in the form of “I did this”, or more generally “actor verb object”. More complex statement forms can also be used.
