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 IPTC is now looking at representing sports data in JSON

1. News in JSON

2. 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"
}

3. 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

6. 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

9. Sports in JSON
• Develop a standard JSON representation of sports data
• Working with the SportsML group
• Decided to manage the work in News in JSON list
– iptc-news-in-json-dev@yahoogroups.com
• Joint working phone calls
• Initial progress
– Established design principles, based on ninjs experience
– Drafted an initial set of 30 to 40 properties
– Represent a sports event within a competition

10. Sports in JSON Experiments
• Early experiment to represent a sports event in JSON
• Using "flattened" team and player structures
– https://gist.github.com/stuartmyles/ba2250e3b1703045f7ac
• Using players "inside" teams
– https://gist.github.com/stuartmyles/b47771cd614b675bd8e0

13. Sports in JSON Experiments
• Our preliminary conclusion is that players “inside” teams
is best
• But the key is that it is important to construct alternatives
and evaluate them using experimental code
