Rating Microform Data

[AdamSC]

So currently I am trying to use microform markup to use the Google Rich Snippets for my thread ratings. The idea here would be to have the rating of the thread (in stars) pass through to the Google results.

I'm pretty sure it would be contained within "SHOWTHREAD" template somewhere in this section:

			<vb:if condition="$show['threadrating']">
				<li class="popupmenu" id="threadrating">
					<h6><a class="popupctrl" href="javascript://">{vb:rawphrase rate_this_thread}</a></h6>
					<div class="popupbody popuphover">
						<form action="threadrate.php" method="post" id='showthread_threadrate_form'>
							<ul>
								<li id="threadrating_current"<vb:if condition="!$show

['rating']">class="hidden"</vb:if> title="{vb:rawphrase thread_rating_x_votes_y_average, {vb:raw thread.votenum}, {vb:raw 

thread.voteavg}}"><label>
									<span class="rating r{vb:raw thread.rating}<vb:if condition="$thread

['rating'] != 5">_{vb:stylevar right}</vb:if>">{vb:rawphrase current_rating}</span>
								</label></li>
								<vb:if condition="$show['ratethread']">
									<li><label for="r5"><span class="rating r5">
										{vb:stylevar dirmark}<input type="radio" name="vote" value="5" 

id="r5" {vb:raw votechecked.5} tabindex="20" /> {vb:rawphrase excellent}
									</span></label></li>
									<li><label for="r4"><span class="rating r4_{vb:stylevar right}">
										{vb:stylevar dirmark}<input type="radio" name="vote" value="4" 

id="r4" {vb:raw votechecked.4} tabindex="21" /> {vb:rawphrase good}
									</span></label></li>
									<li><label for="r3"><span class="rating r3_{vb:stylevar right}">
										{vb:stylevar dirmark}<input type="radio" name="vote" value="3" 

id="r3" {vb:raw votechecked.3} tabindex="22" /> {vb:rawphrase average}
									</span></label></li>
									<li><label for="r2"><span class="rating r2_{vb:stylevar right}">
										{vb:stylevar dirmark}<input type="radio" name="vote" value="2" 

id="r2" {vb:raw votechecked.2} tabindex="23" /> {vb:rawphrase bad}
									</span></label></li>
									<li><label for="r1"><span class="rating r1_{vb:stylevar right}">
										{vb:stylevar dirmark}<input type="radio" name="vote" value="1" 

id="r1" {vb:raw votechecked.1} tabindex="24" /> {vb:rawphrase terrible}
									</span></label></li>
									<li class="formsubmit"><input type="submit" class="button" 

value="{vb:rawphrase vote_now}" tabindex="25" /></li>
								<vb:else />
									<li><label>{vb:rawphrase already_rated_this_thread}</label></li>
								</vb:if>
							</ul>
							<input type="hidden" name="s" value="{vb:raw session.sessionhash}" />
							<input type="hidden" name="securitytoken" value="{vb:raw bbuserinfo.securitytoken}" />
							<input type="hidden" name="t" value="{vb:raw threadid}" />
							<input type="hidden" name="pp" value="{vb:raw perpage}" />
							<input type="hidden" name="page" value="{vb:raw pagenumber}" />
						</form>
					</div>
					<script type="text/javascript">
					<!--
						vB_AJAX_ThreadRate_Init('showthread_threadrate_form', {vb:raw threadinfo.threadid});
					//-->
					</script>
				</li>
			</vb:if>

The problem I face is I am not familiar enough with the VB set up to take a real crack at this

Based on my experience with rich snippets I imagine the markup would look something like:

<div>
  <div itemscope itemtype="http://data-vocabulary.org/Review">
    <span itemprop="itemreviewed">$vb:threadtitle</span>
    Reviewed by <span itemprop="reviewer">$vb:threadauthor</span> on
    <time itemprop="dtreviewed" datetime="2009-01-06">Jan 6</time>.
  </span>
    Rating: <span itemprop="rating">$vb:threadrating</span>
  </div>
</div>

However I'm not even sure if the vb variables I am using in that markup actually exist nevermind how they would fit into this template structure.

Would anyone more familiar with vbulletin want to take a crack at it or push me in the right direction?
