Investigating further into H5P, I started playing with the ability to send xAPI statements to our LRS from Moodle. This will give us valuable Learning Analytics when we start using the tool for formative assessments.
I'd searched everywhere for a quick reference guide to the xAPI statements that are passed for each library. Having not been able to locate one, below is a collated list of the xAPI statements for the H5P Libraries that support xAPI.
