Answer 1

I was learning from this site - http://jolt-demo.appspot.com - there are few very useful examples.
The second source was documentation and viewing issues on page https://github.com/bazaarvoice/jolt/issues
And below is Spec, check if it is what you ment, below are some comments - I hope you understand the rest:
