Codify HTTP interaction

[lhazlewood]

Codify protocol semantics regarding HTTP link traversal for both getting resources and sending data to resource locations.

We should address:

• getting a resource
• sending data to a resource location
• how any http headers or request parameters would or could be utilized in either scenario.

Ion has the method member to specify the HTTP method to use: 7.5. method. The method member can be used in a form (6. Forms). This allows you to specify which endpoint and HTTP method to use to submit a JSON document to: 6.5. Form Submission. To me this is enough for HATEOAS and handles the first two points of your question.

HTTP header support could be added to the spec, but what value would that add?

Edit: For example, JSON:API codifies HTTP semantics in the media type, but that makes the implementation too restrictive, in my opinion. I like that Ion doesn't subscribe HTTP semantics.
