The hReview microformat

hReview is a standard for the (X)HTML markup of reviews developed by an international initiative microformats.org. The reviews marked up by this standard can be processed automatically: the robot can extract the main semantic elements (rating, review text, advantages, disadvantages, and so on) from the page text. The users don't see the markup itself and it doesn't affect the display of the information on the page. The names of the markup fields are specified in the class attribute of the HTML elements.

The current version of the hReview format specification is available at http://microformats.org/wiki/hreview (in English).

The review marked up according to the hReview standard includes entities marked up according to other microformats: the information about the author is marked up based on the hCard standard, the information about the review object is marked up based on the hCalendar or hCard standard, depending on the object type.

Currently Yandex supports extended hReview microformat, which we recommend to use for marking information about organizations.

Microformat markup is processed at the same time as your site is indexed by the Yandex search robot. The extracted data is automatically validated and can later be used in the review snippets on the search result pages or in the Yandex services.

Attention.

Microformats markup is available to everyone the same as the HTML code of the page.
