body: <p>I want to insert Facebook og:meta tags to use for facebook sharer ,in a head of a particular page and this page is not a CMS page.I am thinking of adding these tags through that extension  layout file.
  I know normal titles and description are added like this -></p>
  
  <pre><code>&lt;reference name="head"&gt;
          &lt;action method="setTitle"&gt;&lt;title&gt;My Module Page&lt;/title&gt;&lt;/action&gt;   
   &lt;/reference&gt;
  </code></pre>
