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">

Status
h-item is a microformats.org draft specification. Public discussion on h-item takes place on h-item-feedback and the #microformats irc channel on irc.freenode.net.
Property Details
(stub, add any property explanations here)
Examples in the Wild
- … add any h-item examples you find in the wild
Validating
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"
Background
h-item was extracted from the classic hReview microformat as a way of referring to arbitrary reviewed items which cannot be represented by other microformats but which required a “shell” microformat due to the flat property requirement of microformats 2.
