JSON (Javascript Object Notation)

A data interchange format that is based on the JavaScript programming language and is lightweight and easy for humans and machines to read and write. It consists of attribute-value pairs, such as: amenity:fuel, for a gas station, or surface:paved on as street on a map.

Here's how to describe the iPhone using JSON:

{
"name":"iPhone",
"price":749.99,
"description":"Smartphone from Apple"
}
