title: Categories for Product in schema.org?
body: <p>Using as a reference: <a href="https://support.google.com/webmasters/answer/146750?hl=en" rel="nofollow">https://support.google.com/webmasters/answer/146750?hl=en</a></p>
  
  <p>You will notice under 'Product' that there is a category Property, and furthermore there's an example on down the page: </p>
  
  
  
  <pre class="lang-html prettyprint-override"><code>&lt;span itemprop="category" content="Hardware &gt; Tools &gt; Anvils"&gt;Anvils&lt;/span&gt;
  </code></pre>
  
  <p>which I've mimic'd exactly:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;span itemprop="category" content="kitchen sinks &gt; stainless steel sinks &gt; undermount"&gt;undermount&lt;/span&gt;
  </code></pre>
  
  <p>Yet when I test it with Google's structured data tool, I get the error: </p>
  
  <blockquote>
    <p>Error: Page contains property "category" which is not part of the schema.</p>
  </blockquote>
  
  <p>I realized in the example also, it's using data-vocabulary.org→Product, where I'm using schema.org→Product.</p>
  
  <p>Now on <a href="http://schema.org/Product" rel="nofollow">http://schema.org/Product</a>, it does not have category anywhere mentioned. Does schema.org not offer categories? Or am I missing something?</p>
