I don't understand what is needed that is not already present in  

If you wish to publish a list of reviews plus an average rating at  
the top, then use hReview for each individual review, and an hReview  
at the top containing the average rating. For the average rating, set  
the hReview "reviewer" property to an hCard for the aggregation  
organisation. To avoid repeating the item info in each review, just  
put it in the aggregate review and use the include pattern in the  
individual reviews. The aggregate review can be explicitly marked as  
an aggregate by rel-tagging it so. The aggregate review "description"  
property could be along the lines of "This rating is an average of 38  
people's reviews".
