The Experience API (or xAPI) is a new specification for learning technology that makes it possible to collect data about the wide range of experiences a person has (online and offline). This API captures data in a consistent format about a person or group’s activities from many technologies. Very different systems are able to securely communicate by capturing and sharing this stream of activities using xAPI’s simple vocabulary.
The cmi part of cmi5 stands for 'computer managed instruction', and it is essentially an extra set of rules that harnesses the benefits of xAPI (primarily to enable the capture of eLearning data from anywhere) whilst also adding focus to its otherwise broad, overly flexible specification.
Cinema8 does not support XApi and Cmi5 in the current release , but our learning technology expert group is working on adding Cmi5 export capability to the platform.
