Nice summary! 
I don’t think that P.A.R.A and J.D. treats projects the same though, and I don’t think that the way J.D. prescribes projects matches the P.A.R.A way. They are very different in scope, and I, personally, wouldn’t try to map either to the other. If you go P.A.R.A. to J.D. there is too much overhead. If you go from J.D. to P.A.R.A. there is not enough room. I like the idea that Johnny wrote that a P.A.R.A project is more an ID.
