IPTC has crafted ninjs, a standard for representing news in json.

Version 1.1 of the standard is available now. You'll find examples, code and the schema at http://dev.iptc.org/ninjs and more at https://github.com/iptc/newsinjson

News in JSON Stuart Myles * Associated Press * 10th March 2014 http://www.flickr.com/photos/toffaelrashid/7574046808/

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": "Evan", "familyname": "Sandhaus" } ]} © 2014 IPTC (www.iptc.org) All rights reserved 2

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 © 2014 IPTC (www.iptc.org) All rights reserved 3
