h-review is a simple, open format for publishing reviews on the web. h-review is one of several open microformat draft standards suitable for embedding data in HTML/HTML5 on the web.

h-review is the microformats-2 update to hReview.

Example

Here is a simple review example:

<div class="h-review">
  <h1 class="p-name">Microformats: Worth the hassle?</h1>
  
  <blockquote>
    <a class="p-item h-item" href="http://microformats.org">Microformats</a> are the simplest way to publish structured data on the web.
  </blockquote>
  
  <p>
    <data class="p-rating" value="5">★★★★★</data>
    Published <time class="dt-reviewed" datetime="2013-06-12 12:00:00">12<sup>th</sup> June 2013</time>
    by <a class="p-reviewer h-card" href="http://example.com">Joe Bloggs</a>.
  </p>
  
  <div class="e-description">
    <p>Yes, microformats are undoubtedly great. Unless of course you want to mark up volcanoes with fax machines, in which case schema.org is better suited to your needs.</p>
  </div>
</div>

Get started

The class h-review is a root class name that indicates the presence of an h-review.

p-name, p-item, p-reviewer and the other property classnames listed below defined elements as properties of the h-review.

See microformats-2-parsing to learn more about property class names.

Properties

h-review properties, inside an element with class h-review:

  • p-name - name of the review
  • p-item - thing been reviewed i.e. business or person (h-card), event (h-event), place (h-adr or h-geo), product (h-product), website, url, or other item (h-item).
  • p-reviewer - person who authored the review, optionally a nested h-card
  • dt-reviewed - date time of when the review was written
  • p-rating - value from 1-5 indicating a rating for the item (5 best).
  • p-best - define best rating value. can be numerically lower than worst.
  • p-worst - define worst rating value. can be numerically higher than best.
  • e-description - the full text written evaluation and opinion of the reviewer
  • p-category - freeform categories or tags applied to the item by the reviewer
  • u-url - review permalink URL

Status

h-review is a microformats.org draft specification. Public discussion on h-review takes place on h-review-feedback, the #microformats irc channel on irc.freenode.net, and microformats-new mailing list.

h-review is ready to use and implemented in the wild, but for backwards compatibility you should also mark h-reviews up with classic hReview classnames.

Backward Compatiblity

Publisher Compatibility

For backward compatibility, you may wish to use classic hReview classnames in addition to the more future-proof h-review properties, for example:

<div class="h-review hreview">
  <h1 class="p-name fn">My great review</h1>
</div>

Parser Compatibility

Microformats parsers should detect classic properties and parse them as microformats 2 properties. If an "h-review" is found, don't look for an "hReview" on the same element.

Compatibility root class name: hreview

Properties: (parsed as p- plain text unless otherwise specified)

  • summary parse as p-name
  • fn - parse as p-name of the item being reviewed (p-item h-item p-name)
  • photo - parse as u-photo of the item being reviewed (p-item h-item u-photo)
  • url - parse as u-url of the item being reviewed (p-item h-item u-url)
  • reviewer - including compat root vcard in the absence of h-card
  • dtreviewed - parse as dt-
  • rating
  • best
  • worst
  • description - parse as e-
  • rel=tag - parse as p-category
  • rel="self bookmark" - parse as u-url. note that rel attribute value is treated as a space separated set, thus any presence of "self" and "bookmark" within such a set in a rel value is accepted.

Note: The hReview format has three properties which make use of rel attribute, these are tag, permalink (via the self and bookmark values) and license. Microformats 2 parsers SHOULD map these URLs into the page scoped rel collection.

Background

h-review is based on the existing hReview specification, which was extracted from hCard in order to allow it to be used for applications other than contact information.
