The context links object properties in a JSON document to concepts in an <a href="/wiki/Ontology_(information_science)" title="Ontology (information science)">ontology</a>. In order to map the JSON-LD syntax to RDF, JSON-LD allows values to be coerced to a specified type or to be tagged with a language. A context can be embedded directly in a JSON-LD document or put into a separate file and referenced from different documents (from traditional JSON documents via an <a href="/wiki/Hypertext_Transfer_Protocol" class="mw-redirect" title="Hypertext Transfer Protocol">HTTP</a> Link <a href="/wiki/List_of_HTTP_header_fields" title="List of HTTP header fields">header</a>). </p> <div class="mw-heading mw-heading2"><h2 id="Example">Example</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=JSON-LD&action=edit&section=2" title="Edit section: Example"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-highlight mw-highlight-lang-json-ld mw-content-ltr" dir="ltr"><pre><span></span><span class="p">{</span> <span class="w"> </span><span class="nd">"@context"</span><span class="p">:</span><span class="w"> </span><span class="p">{</span> <span class="w"> </span><span class="nt">"name"</span><span class="p">:</span><span class="w"> </span><span class="s2">"http://xmlns.com/foaf/0.1/name"</span><span class="p">,</span> <span class="w"> </span><span class="nt">"homepage"</span><span class="p">:</span><span class="w"> </span><span class="p">{</span> <span class="w"> </span><span class="nd">"@id"</span><span class="p">:</span><span class="w"> </span><span class="s2">"http://xmlns.com/foaf/0.1/workplaceHomepage"</span><span class="p">,</span> <span class="w"> </span><span class="nd">"@type"</span><span class="p">:</span><span class="w"> </span><span class="s2">"@id"</span> <span class="w"> </span><span class="p">},</span> <span class="w"> </span><span class="nt">"Person"</span><span class="p">:</span><span class="w"> </span><span class="s2">"http://xmlns.com/foaf/0.1/Person"</span> <span class="w"> </span><span class="p">},</span> <span class="w"> </span><span class="nd">"@id"</span><span class="p">:</span><span class="w"> </span><span class="s2">"https://me.example.com"</span><span class="p">,</span> <span class="w"> </span><span class="nd">"@type"</span><span class="p">:</span><span class="w"> </span><span class="s2">"Person"</span><span class="p">,</span> <span class="w"> </span><span class="nt">"name"</span><span class="p">:</span><span class="w"> </span><span class="s2">"John Smith"</span><span class="p">,</span> <span class="w"> </span><span class="nt">"homepage"</span><span class="p">:</span><span class="w"> </span><span class="s2">"https://www.example.com/"</span> <span class="p">}</span> </pre></div> <p>The example above describes a person, based on the <a href="/wiki/FOAF_(ontology)" class="mw-redirect" title="FOAF (ontology)">FOAF (friend of a friend) ontology</a>. First, the two JSON properties <code>name</code> and <code>homepage</code> and the type <code>Person</code> are mapped to concepts in the FOAF vocabulary and the value of the <code>homepage</code> property is specified to be of the type <code>@id</code>. In other words, the homepage id is specified to be an <a href="/wiki/Internationalized_Resource_Identifier" title="Internationalized Resource Identifier">IRI</a> in the context definition. Based on the RDF model, this allows the person described in the document to be unambiguously identified by an <a href="/wiki/Internationalized_Resource_Identifier" title="Internationalized Resource Identifier">IRI</a>. The use of resolvable IRIs allows RDF documents containing more information to be <a href="/wiki/Transclusion" title="Transclusion">transcluded</a> which enables clients to discover new data by simply following those links; this principle is known as 'Follow Your Nose'.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> </p><p>By having all data semantically annotated as in the example, an RDF processor can identify that the document contains information about a person (<code>@type</code>) and if the processor understands the FOAF vocabulary it can determine which properties specify the person's name and homepage. </p> <div class="mw-heading mw-heading2"><h2 id="Use">Use</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=JSON-LD&action=edit&section=3" title="Edit section: Use"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The encoding is used by <a href="/wiki/Schema.org" title="Schema.org">Schema.org</a>,<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup> <a href="/wiki/Google_Knowledge_Graph" title="Google Knowledge Graph">Google Knowledge Graph</a>,<sup id="cite_ref-9" class="reference"><a href="#cite_note-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup> and used mostly for <a href="/wiki/Search_engine_optimization" title="Search engine optimization">search engine optimization</a> activities.
