Tantek, thanks for reviewing the hreview-aggregate draft.

Per your suggestion, I've added several examples of sites that have
separate counts for the number of ratings/votes and the number of
reviews. The examples are here:

And to re-iterate the problem and proposal -- it's valuable to be able
to differentiate between the number of reviews on a page vs the number
of votes that contribute towards an average rating. For example, a
page with 4 reviews is much more interesting than a page with 4 votes
and 0 reviews. We'd like to extend the hreview-aggregate schema to
include some method of differentiating these two different counts. The
proposal is to add a new property called "votes"; more details are

As before I'm happy to hear feedback on the proposal or any alternatives.
