How do you represent an object in JSON?
JSON objects are written in key/value pairs. JSON objects are surrounded by curly braces { } . Keys must be strings, and values must be a valid JSON data type (string, number, object, array, boolean or null). Keys and values are separated by a colon.
How do I include references to other resources in JSON document?
Presenting the fully qualified URL for every resource aids discoverability by allowing for new resources to be consumed by just embedding a new reference (link). This works well for JSON because JSON is schema-less; adding new fields will not break functionality and will maintain backwards compatibility.
How do I reference a JSON schema?

What is a JSON property?

JSON structure. As described above, a JSON is a string whose format very much resembles JavaScript object literal format. You can include the same basic data types inside JSON as you can in a standard JavaScript object — strings, numbers, arrays, booleans, and other object literals.
