Get started

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

p-name, p-price, u-photo and the other property classnames listed below define elements as properties of the h-product.

See microformats-2-parsing to learn more about property classnames.

Properties

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

• p-name - name of the product
• u-photo - photo of the product
• p-brand - manufacturer, can also be embedded h-card
  Main article: h-card
• p-category - freeform categories or tags applied to the item by the reviewer
• e-description
• u-url - URL of the product
• u-identifier - includes type (e.g. mpn, upc, isbn, issn, sn, vin, sku etc.) and value.
• p-review - a review of the product, optionally embedded h-review
  Main article: h-review
• p-price - retail price of the product

Status

h-product is a microformats.org draft specification. Public discussion on h-product takes place on h-product-feedback and the #microformats irc channel on irc.freenode.net.

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

Property Details

(stub, add any property explanations here)

TODO: u-identifier supposedly “includes type” — how so? URI scheme? Need examples of how to mark up the various different identifier types.

price was an experimental property which has real world adoption due to Google and Bing search support of hProduct. Due to this it has been included in the updated h-product spec.

Examples in the Wild

• Barnaby Walters’ posting UI is marked up with h-product and experimental h-x-app markup so that authorization UIs can provide a better experience whilst authorizing, without having to pre-register apps and upload logos
• … add any h-product examples you find in the wild

Validating

Main article: validators

Test and validate microformats2 markup in general with:

• https://pin13.net/mf2/ - enter your markup directly
• https://pin13.net/ - enter a URL to a page to test where it says "Microformats Parser"

Backward Compatibility

Publisher Compatibility

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

<div class="h-product hproduct">
  <h1 class="p-name fn">Product Name</h1>
</div>

Parser Compatibility

Microformats parsers SHOULD detect classic properties only if a classic root class name is found and parse them as microformats2 properties.

If an "h-product" is found, don't look for an "hProduct" on the same element.

Compatibility root class name: hProduct

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

• fn - parse as p-name
• photo - parse as u-
• brand
• category
• description
• identifier - parse as u-
• url - parse as u-
• review - including compat root class hreview in the absence of h-review
• price

Background

h-product is based on the existing hProduct specification.
