JSON-LD

JSON-LD is an easy-to-use JSON-based linked data format that defines the concept ofcontext to specify the vocabulary for types and properties. Gmail supportsJSON-LD data embedded in HTML documents with the@context ofschema.org, as in the following example:

<scripttype="application/ld+json">{"@context":"http://schema.org","@type":"Person","name":"John Doe","jobTitle":"Graduate research assistant","affiliation":"University of Dreams","additionalName":"Johnny","url":"http://www.example.com","address":{"@type":"PostalAddress","streetAddress":"1234 Peach Drive","addressLocality":"Wonderland","addressRegion":"Georgia"}}</script>
Note: the@type key is a reserved key name and should contain either a full type URI or a URI fragment (in which case ahttp://schema.org/ prefix, derived from the supplied data-context attribute, is assumed).

The full specifications and requirements for the JSON-LD syntax are available onjson-ld.org, and you can also use ourSchema Validator tool to try out JSON-LD and debug your markup.
