  },
  "description":{
    "@@body":"Description:",
    "@type":"textarea",
    "@value":"Default text"
  }
}
== Proposal B: REST-oriented process ==
From [Kyle Cordes], for the discovery of the parameters:
* You discover the URL of a service by some means.
* You GET that URL, which returns an HTML form.
* The HTML form describes where to POST to invoke that service, and what
parameters can be passed in that POST.  In some cases, it will use
<selects>s to describe what options are valid for a parameter.
* In most cases, the form will be interspersed with human readable text,
to explain the meaning of the parameters (a machine-understandable way
to explain parameter meaning, sounds like an AI problem...)
* You (the user of a web browser, or a piece of software
programmatically using the server) populate the parameters and POST them
to the URL you discovered via the form.
* You get back a response, which might be an error message about a
parameter problem, or might be a respresentation of the "answer".
[OlaBerg] says: This is exactly what I do, and it works great! In fact, I
use it both for POST-API and GET-API. A set of forms defines a REST-ful
API.

Forms Brainstorming

This page collects ideas from forms-examples how to best encode form data into a microformat

Proposal A: DETH - Dictionaries Encoding/Transmitting HTML

Rules (Strawman)

  1. Only use XHTML Basic Forms Module
  2. Must use action with appropriate URI (no scripts)
  3. Recommend: use a label with every input
  4. Make the for of the label match the id of input
  5. Group label with input using
  6. Always place submit and reset outside grouping

Questions for further research

  1. How to specify whether a field is optional or required?
    1. Suggestion: the label contains a * ?

Patterns
