JSON-LD

JSON-LD stands for JavaScript Object Notation for Linked Data and is intended to be a pure data exchange format for directed graphs and is designed to be usable directly as JSON (without knowledge of RDF). It can be used, however, in conjuction with RDF.
A JSON-LD document is always a valid JSON document. So, they can be processed with standared JSON libraries (such as the Perl module JSON).
JSON-LD targets developers who are already familiar with JSON. They only need to learn two new keywords (@context and @id) to use the basic functionality of JSON-LD.

Example

<script type="application/ld+json">
{
  "@context": "http://schema.org",
  "@type": "Organization",
  "url": "http://renenyffenegger.ch",
  "contactPoint": [{
    "@type": "ContactPoint",
    "telephone": "+41-76-558-70-68",
    "contactType": "sales"
  }]
}
</script>
