JSON Path query language

Great discussion, very compatible with the graph machine.
$.store.book[*].author the authors of all books in the store
$..author all authors
$.store.* all things in store, which are some books and a red bicycle.
$.store..price the price of everything in the store.
$..book[2] the third book

They use the dollar as the understood start of the graph, or relative start. They got brackets. They have the double dot thing going. You bet, this is real close to a graph layer. We will get interleaved variable expressions, but right no the syntax says we can deliver undifferentiated script in bounded segments. So, they are looking at graph traversal. Actually, I know how these folks think, graph traversal has been on their back burner for 10 years.
