Remind Me: What is JSON?JSON = JavaScript Object Notation http://json.org/
Name / value pairs: a fieldname in quotes, a colon, a value in quotes
"givenname" : "Evan"
Objects: written inside curly braces, may contain multiple NVPs
{"givenname" : "Evan", "familyname" : "Sandhaus"}
Arrays: Written inside square braces, may contain multiple objects{"iptcdelegates": [ { "givenname": "Jayson", "familyname": “Lorenzen"}, { "givenname": "Jeremy", "familyname": "Brooks"}, { "givenname": "Trond", "familyname": "Huso" }]}

Remind Me: Why News in JSON?
Lightweight, easy to parse format
Increasingly popular alternative to / replacement for XML
Two principle use cases:
data interchange (e.g. APIs) with an emphasis on partial representation
data at rest (e.g. search engines like Elastic Search or MongoDB)
Not simply translating from any existing XML standard into JSON
Determine how to represent key properties and structures
Hand crafted, rather than mechanically translating from XML into JSON
Goal: comprehensive standard, lightweight instance documents

ninjs 1.1
• ninjs is a JSON representation of a news item– Text, Photo, Graphic, Video, Audio, Package
• You can represent a complete item, with all properties– For instance in an internal CMS like MongoDB
• Or you may want to convey key properties– For instance as an API response
• The representationtype property indicates how complete– Either “full” or “partial”
• Associations are themselves ninjs documents– You may include complete or partial representations
