experience API (Tin Can)
Now you may store more and more data about what your user is doing with the H5Ps you create. How many attempts did she use? What scores did she get? How much time did she spend? All of this is available now, and more statements will be added - when did she stop the video? What did she answer when? What slides has she seen?
You may also use the xAPI to adapt to what the user does in the H5P. For instance you may display more content on a completed event with full score. H5P uses xAPI internally for the adaptivity, in the question set and in the presentation content types.
