This item was posted last September but it showed up in my feed reader only today, and it's certainly worth passing along. It describes cmi5 (EduTech wiki says "cmi5 probably stands for computer managed instruction, fifth attempt"), which has been in the works for a number of years now. If I had to summarize it in a sentence, I would say that cmi5 basically takes SCORM and combines it with xAPI. In other words, it describes the conditions for launching and running a learning resource, and includes information about how to record the activities undertaken using that learning resource. For more, see the cmi5 catapult, "a freely available, open-source cmi5 content player and cmi5 conformance test suite for use by DoD stakeholders or and other e-learning technology vendors."
