- W3C JSON-LD 1.1
JSON with a @context that gives its keys global meaning — RDF for people who would rather not look at XML.
The trick is that the context maps short keys to URIs, so "name" unambiguously means schema.org/name and not some other system's name field. The document stays ordinary JSON that existing code can read without caring.
A W3C recommendation since 2014. Its major practical use is Schema.org markup inside <script type="application/ld+json">, which Google prefers over microdata because it sits separately from the presentation.
