JSON-LD

JSON-LD is a simple JSON-based Linked Data format.

It is also the recommeded Open Annotation serialization format, and the default format used to represent annotations in the RESTful Open Annotation API.

The benefits of JSON-LD include

• It is JSON: easy to read and write, and increasingly the de facto standard language of web APIs.
• It is RDF: the language of Linked Data, allowing the use of extensive existing resources.
• It adds links to JSON, making it possible to write better RESTful JSON APIs.
• It has great documentation, including an exceptionally readable W3C specification.
• It has good library support and learning tools.

Given the quality and quantity of existing material on JSON-LD, we won’t try to present it here but will instead simply refer interested readers to json-ld.org. Some basics are discussed also in the presentation of the OA context.
