Suggestion: use RDFa Lite instead of class names to mark up objects in HTML where possible:

Old HTML, using class to mean both "type" and "property":

<article class="movie">
  <div class="name"></div>
  <div class="director"></div>
  <div class="date"></div>
  <div class="studio"></div>

New HTML, using vocab + typeof for the "type" of object and property for each "property":

<article vocab="" typeof="Movie">
  <div property="name"></div>
  <div property="director"></div>
  <div property="datePublished"></div>
  <div property="productionCompany"></div>

See this list of movies for an example, and the accompanying CSS.
