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 reviewp-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-carddt-reviewed
- date time of when the review was writtenp-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 reviewerp-category
- freeform categories or tags applied to the item by the revieweru-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 asp-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-carddtreviewed
- parse as dt-rating
best
worst
description
- parse as e-rel=tag
- parse as p-categoryrel="self bookmark"
- parse as u-url. note thatrel
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.
