I'm conforming to the authors definition, as you present it. Under these criteria, Sinatra is categorically closer to rails than a Jason library. What might an http server library look like? It would have a function that blocks on accepting a socket, a function that parses the socket contents into a data structure, and a function that lets you send a response. That's not what Sinatra looks like, at all. If you make a claim otherwise, you are on shaky ground. Let go.
