This slides was used in ISO/IEC JTC1 SC36/WG8 meeting in December 1 2015. Also this is following thinking from “quick review for xAPI and IMS Caliper” (ISO/IEC JTC1 SC36/WG8 first webinar in Nov. 11, 2015). Through this slides I'm thinking two phases for mapping both data format. One is structural and syntactic mapping and the other is ontological mapping. Enjoy this trivial idea and please give my your valuable comments.
