April’s Obsidian Chat topic was xAPI. We had xAPI expert Art Werkenthin from RISC, Inc., join us to share his knowledge and insight on the topic. Art is a member of the ADL CMI-5 committee, and is an expert on both xAPI and CMI-5. This has been, by far, my favorite Obsidian chat. xAPI is murky for a lot of folks, and the responses shared were extremely helpful in learning more about the topic.
