You're forgetting form-style affordance. For example, if you were using HTML as your media type, the equivalent of the first example would be

  <form method="get" action="/me">
    <input type="text" name="access_token" />
    <input type="text" name="fields" />
  </form>

Actually, you explicitly _don't_ want this. That's what hypermedia APIs are trying to remove.

We're replying to each other in separate comment threads :-), but this input form is still coupling--you can't add/remove/change the access_tokens/fields without clients breaking. Humans can handle that. Software can't.

That's why I think hypermedia makes all sorts of sense for explaining why the www is awesome--it change deal, users will adapt. But IMO it falls flat as some new paradigm for building client/server systems.

Hm? I am skeptical...any links/explanations?

Haha! Ping-pong!

I know of one company which you've absolutely heard of who has a 30-person team building a hypermedia API. They haven't talked about it publicly because they see it as a strategic advantage.

This year will be the year of code and examples; last time I was in San Fransisco, 5 different startups came up to me and told me that hypermedia is solving their problems. Expect to see more of this going on soon.

Mike Amundsen's "Building Hypermedia APIs in HTML5 and Node" has a pretty big section on this, and my book has a section entitled "APIs should expose workflows."

I previously commented more about it here: http://news.ycombinator.com/item?id=4951477

RPC APIs expose functions, SOAP/"REST" APIs expose objects, hypermedia APIs expose processes.
