      <h1 property="dcterms:title">RDFa Core Initial Context</h1>
      <p>This list of predefined prefixes have been defined for RDFa as an <a  href="https://www.w3.org/TR/rdfa-core/#s_initialcontexts">“initial context”</a>: essentially, RDFa users can use these prefixes without having the obligation of defining the prefixes in the HTML code. The same list of prefixes have also been defined for JSON-LD as a <a  href="https://www.w3.org/TR/json-ld/#the-context">JSON-LD Context</a> at the URI <code>https://www.w3.org/2013/json-ld-context/rdfa11</code>; JSON-LD users can use the <code>@context</code> key with that URI as a shorthand to use the same prefixes.</p> </div>
