Frigga - AS3 JSON Schema Validator
==================================

Take a look to the spec here:

http://tools.ietf.org/html/draft-zyp-json-schema-03

It's a work in progress. It supports most of the "Core Schema Definition", including:
type
properties
items
minimum
maximum
exclusiveMinimum
exclusiveMaximum
minItems
maxItems
pattern
minLength
maxLength
enum
default
title
description
format
id

Usage example:
--------------

var anObject : Object = {
	id : "shoe 123",
	name : "Shoes",
	price : -20
};
	
var schema : Object = {
	name : "Product",
	description : "Product definition",
	type : "object",
	properties : {
		id : {
			type : "number",
			description : "Product identifier"
		},
		name : {
			description : "Name of the product",
			type : "string"
		},
		price : {
			type : "number",
			minimum : 0
		}
	}
}; 

var frigga : Frigga = Frigga.forSchema(this.schema);
var report : FriggaReport = frigga.validate(this.anObject);
trace("Is valid? " + report.isValid());
trace(report.getMessagesAsString());

... and here is the output:

Is valid? false
errors (message | property | actualValue): 
number is out of range | price | -20
invalid type on property | id | string


To see more examples take a look to the unit tests:

TBD:
----

- Add support for "tuple typing"
- Add a repository of schemas to handle schema composition by reference (noy it handles schema composition inline)
- Add support for "Hyper Schema"
- Add support for the following parts of the "Core Schema Definition":
patternProxperties
additionalProperties
additionalItems
required
dependencies
uniqueItems
divisibleBy
disallow
extends
$ref
$schema
