title: how to use schema.org metadata on a review for multiple ratings?
body: <p>I need to markup the review metadata for a product, but the review will have multiple ratings like service, satisfaction, quality, lifetime etc in the original schema.org documentation for review (<a href="http://schema.org/Review" rel="nofollow">http://schema.org/Review</a>) there is only property/field: <code>reviewRating</code> using this i can only use it for one field but i need to provide metadata for all the fields, is there a solution for that?</p>
  
  <p>Thanks.</p>
