Let's take this markup which describes
 Two places 
 with the name "Tsujido" and "Meguro
 and their associated longitude and latitude.
 <ul vocab="http://schema.org/">
 <li typeof="Place">
 <span property="name">Tsujido</span>
 <div property="geo"
 typeof="GeoCoordinates">
 <meta property="latitude" content="35.336833"/>
 <meta property="longitude" content="139.447083"/>
 </div>
 </li>
 <li typeof="Place">
 <span property="name">Meguro</span>
 <div property="geo"
 typeof="GeoCoordinates">
 <meta property="latitude" content="35.633983"/>
 <meta property="longitude" content="139.71600"/>
 </div>
 </li>
 </ul>
I would love to be able to do something such as 
 "for each place return the longitude"
 var places = document.getItems('http://schema.org/Place');
 for (var i = places.length - 1; i >= 0; i--) {
 longitude = places[i].properties['longitude']
 console.log(longitude);
 };
And then in the console:
 139.71600
 139.447083
