I'm passing this along. I have not had a chance to do a deeper dive into it. GitHub keeps returning this message each time "(Sorry about that, but we can’t show files that are this big right now.)."
In sum and substance, this work is being done at the National Information Electronic Model, NIEM for short, work which has recently been released into the wild by the DOD. I hope you find it interesting and pertinent to the deep fake work, especially around biometrics.
