+
+This is a *very* simple example of a JSON schema. There is only one property.

+
+| Property | Type | Required | Defined by |
+|----------|------|----------|------------|
+| [@id](#@id) | `string` | Optional | Identifiable (this schema) |
+| `*` | any | Additional | this schema *allows* additional properties |
+
+## @id
+
+A unique identifier given to every addressable thing.
+
+`@id`
+* is optional
+* type: `string`
+* defined in this schema
+
+### @id Type
+
+
+`string`
+* format: `uri` – Uniformous Resource Identifier (according to [RFC3986](http://tools.ietf.org/html/rfc3986))
