Orderly is a textual format for describing JSON. Orderly can be compiled into JSONSchema. It is designed to be easy to read and write.

Depends on Node.js and npm:

npm install orderly -g

var orderly = require("orderly");
var orderlySource = "array {};";
var jsonSchemaSource = orderly.compile(orderlySource);
var jsonSchemaObject = orderly.parse(orderlySource);
print(JSON.stringify(jsonSchemaObject));

usage: orderly <file> [options]
file     file to parse; otherwise uses stdin
options:
   -v, --version                 print version and exit
   -o FILE, --output-file FILE   write output to the file
   -t CHAR, --indent CHAR        character(s) to use for indentation

The minified, standalone version of orderly.js is found in web/orderly.js. Just include it in your web page to use the orderly object:

<script src="json2.js"></script>
<script src="orderly.js"></script>
<script>
    var orderlySource = "array {};";
    var jsonSchemaSource = orderly.compile(orderlySource);
    var jsonSchemaObject = orderly.parse(orderlySource);
</script>

Orderly.js includes it's own JSON parser, but older browsers will need a JSON stringifier such as json2.js in order to compile to JSONSchema.
