Average rating and total ratings

Hello,

To get into the point, Can we have Average rating and total ratings?

Total ratings is easy: votes up + votes down
Avarage rating: can be achieved by;

One thumb up = 5 rating
One thumb down = 1 rating

By this formula we can get average rating like other rating plugins.

Of course, this is a good feature to add schema rating feature for google.

Thanks for effort
