Simple JSON schema

Why

Because other JSON schemas are

• too complicated - too much syntax to remember
• not powerfull enough - try writing a JSON schema for the example bellow and you'll see

When writing a 3dots schema you start with an example and replace repeating parts with "..." operator. Plus 2 built in types String and Int. You can substitute , with pipe |. Pipe means OR. The opearands are PMS (previous meaningful section) and the following meaningful section.

How

There is just one operator "..." called three dots. It will repeat the previous meanigful section N times. What is a meanigful section? Standard things like objects, arrays, integers and strings but also:

String: String,...

Example schema

{
	"id" : Int,
	"children" : [Int,...],
	"objects" : [
		{"name": String}|
		{"price": Int},
		...
	],
	"lookup" : {
		String : String,
		...
	},
	"coordinates" : [
		[ Int, Int, {String : String} ],
		...
	]
}

Try

git clone https://github.com/towhans/3dots.git
cd 3dots
perl generate.pl

Status

This is a POC. It can only generate example data from schemas. Validation is on the TODO list. Comments are welcome.
