ninjs is http://www.iptc.org/'s standard for describing news content in JSON format.
The ninjs JSON Schema is available in this repository and at http://www.iptc.org/std/ninjs/ninjs-schema_1.2.json
More extensive documentation, created from the source files in the documentation folder in this repository, can be found at https://www.iptc.org/std/ninjs/userguide/
The examples folder contains example files, including some supplied
by Business Wire. Examples show how NewsML 1.2 files convert to their
equivalents in ninjs.
To run unit tests in the validation/test_suite folder against each
of the ninjs 1.0, 1.1 and 1.2 schemas, run the following tool in a
command/terminal window:
