title: There is a difference between using Json or Metadata working with Structured Data?
body: <p>I'm implementing Structured Data at a website, And I saw that I can use the Json to implement my Rich Cards on my page. Before this I was using:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;meta property="og:url" content="http://site.com.br/"&gt;
  
  &lt;!--google--&gt;
  &lt;meta itemprop="name" content="SITE eXEMPLE"&gt;
  &lt;meta itemscope="" itemtype="http://www.site.com.br/"&gt;
  &lt;meta itemprop="headline" content="Description of a SITE FOR | Exemple"&gt;
  &lt;!-- And that's it --&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>There is a difference on performance or reading of the code?</p>
