The ongoing work of learning standards
SEPTEMBER 15, 2017
Consider the internet; developments on top of the TCP/IP protocol like SMTP and HTML allowed a variety of tools to work together to bring us email and the world wide web. For interactivity, we originally used Flash, and now have HTML 5 as a more secure and reliable replacement. Initially, when you developed eLearning, you were pretty much dependent on the tool you developed it in. In addition, IMS has released a specification for activity very much like xAPI, called Caliper.
