_layout.btl 里 html5 Microdata 起到什么作用？

  <div itemscope itemtype="http://schema.org/WebSite">
    <meta itemprop="url" content="${conf["website.urlbase"]}"/>
    <form id='search_form' class='navbar-search' action="${ctxPath}/yvr/search" itemprop="potentialAction" itemscope itemtype="http://schema.org/SearchAction">
      <meta itemprop="target" content="${conf["website.urlbase"]}${ctxPath}/yvr/search?q={q}"/>
      <input type='text' id='q' name='q' class='search-query span3' value='' itemprop="query-input" required/>
    </form>
  </div>

和下面这段有什么区别呢？

   这段
   <form id='search_form' class='navbar-search' action="${ctxPath}/yvr/search" >
      <input type='text' id='q' name='q' class='search-query span3' value='' required/>
    </form>
