h-item is a simple, open format for publishing details about arbitrary items. h-item is one of several open microformat draft standards suitable for embedding data in HTML.

In practice, h-item is almost never used on its own, but rather as the p-item in an h-review if the item being reviewed cannot otherwise be represented by either an h-card, h-product, h-event, or other specific microformat.

Example

As the only properties defined by h-item are p-name, u-url and u-photo, in practice only the root class name is ever actually required thanks to microformats-2-implied-properties. Explicit properties may be needed for unusual markup structures or to represent multiple values, e.g. multiple URLs, photos. etc..

<a class="h-item" href="http://example.org/items/1">
  <img src="http://example.org/items/1/photo.png" alt="" />
  The Item Name
</a>

          "The Item Name"
