How do we get this data?

How do we get this data? With RDFa markup: <div xmlns:v="http://rdf.data-vocabulary.org/#" typeof="v:Review-aggregate" > <span rel=“v:itemreviewed" > <h1 property="v:name" > Drooling Dog Bar B Q </h1> <img rel="v:rating" src="stars_map.png" alt="4 star rating" /> <em>based on <span property="v:count"> 15 </span> reviews</em> </span> </div> With Microformats markup: <div class="hreview-aggregate" > <span class="item vcard" > <h1 class="fn org" > Drooling Dog Bar B Q </h1> <img class="rating average" src= "stars_map.png" alt="4 star rating" /> <em>based on <span class="count"> 15 </span> reviews</em> </span> </div>
