If you were going to build a JSON based file system today, then I would study the Newton’s Soup which was based on frames. It was pretty cool and had some interesting capabilities (remove half the storage from a running system, ok what’s next). I would imagine queries would make a reappearance in a much nicer form.

Thats exactly what I thought. Newton Soups and NewtonScript were both awesome. I miss that kind of system these days, it still amazes me how it was all integrated.
