News in JSON

Stuart Myles * Associated Press * 10th March 2014http://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" }]}

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 1.0

• 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

NINJS 1.1

• Improving on NINJS 1.0– Geo data– Usage terms– Urgency (in late breaking changes)

© 2014 IPTC (www.iptc.org) All rights reserved 10

Geo Data

• Extend “place” with machine-readable geo data– Such as lat and long

• There are several ways to represent geo data– Including GeoJSON, KML and GML

• Add a “geometry_” pattern property to NINJS• Allow providers to select the geo data representation(s)

that best fits their needs

Usage Terms

• Natural language restrictions specific to this ninjs object.

• In addition to any machine-readable description, such as via RightsML

• http://www.w3.org/community/odrl/work/json/

• Add a "usageterms" string property– A natural-language statement about the usage terms pertaining

to the content
