Gregory's ServerVideo encoding is yet another example of an attempt to create the "one true file format to rule them all...but be flexible...and self-descriptive...all at once"
Someday you should look at nautical charts and the layer upon layer of utterly insane abstractions and "one true formats" (ISO 8211, IHO S57&S58, etc.)
Bugfests, all of them
I have always low-key wondered if such fustercluck standards could be used as attack vectors against the world's oceangoing vessels (shudder!)
