I'm trying to add more structural information to my webpages by using the Microdata format with Schema.org. The procedure seems straight forward but I'm having issues validating my results in the Google Rich Snippets Testing Tool.
Check out this review page, here I'm using the
reviewRating property item to specify rating values for that particular review. I followed the same format as defined in
Rating but this markup fails validation in Google's Rich Snippet Testing Tool with the following error info:
Item Type: http://schema.org/rating reviewrating = 5 ratingvalue = 5 Warning: Property "reviewrating" was not found.
