Neither xAPI nor any of the related IEEE LTSC data standards naturally gravitate towards living in silos. They are all designed to be interconnected and they thrive on interconnectedness.

They only end up in silos if you put them in silos.

The Interservice / Industry Training, Simulation and Education Conference (I/ITSEC) is the world's largest modeling, simulation and training event. It’s a hotbed of innovation in simulation and training technologies as well as being arguably the most important venue for the presentation of research in the space.

With an objective to provide “a data strategy for measuring the longitudinal impact of synthetic, semi-synthetic, and live training experiences on individual and team competency development,” STEEL-R brings together a variety of standards-based capabilities from the world of synthetic scenario design with the core standards-based capabilities of ADL’s Total Learning Architecture (TLA).
