h-entry is a simple, open format for episodic or datestamped content on the web. h-entry is often used with content intended to be syndicated, e.g. blog posts. h-entry is one of several open microformat draft standards suitable for embedding data in HTML/HTML5.

h-entry is the microformats2 update to hAtom.



Here is a simple blog post example:

<article class="h-entry">
  <h1 class="p-name">Microformats are amazing</h1>
  <p>Published by <a class="p-author h-card">W. Developer</a>
     on <time class="dt-published" datetime="2013-06-13 12:00:00">13<sup>th</sup> June 2013</time>
  <p class="p-summary">In which I extoll the virtues of using microformats.</p>
  <div class="e-content">
    <p>Blah blah blah</p>

Get started

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

p-name, p-author, dt-published and the other h-entry property classnames listed below define properties of the h-entry.

See microformats2-parsing to learn more about property classnames.


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

The following experimental properties are in use in the wild but are not yet part of the spec:

The following properties are proposed additions based on various existing link preview markup conventions which are not yet used in the wild (Related: link-preview-brainstorming)

All properties are optional.


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

h-entry is ready to use and implemented in the wild, but for backwards compatibility you should also mark h-entries up as classic hAtom entries.

Property Details

(stub, to be expanded)

hAtom-specific implementations that perform custom display or translation (e.g. to Atom XML) SHOULD prefer p-name over p-entry-title, and use p-entry-title value(s) as a fallback if there is no p-name.


  • What is the p-name of a note?
    • A few options, from simplest to most detailed.
      • same as the p-content/e-content property.
      • same as the title element on the note permalink post page. When publishing a note on its own permalink post page, the contents of the note are likely abbreviated for the title of the page. The same abbreviation can be used for the p-name.
      • first sentence of the p-content/e-content property. It may be better for syndication and link-preview purposes to provide just the first sentence of the note as the p-name. Similarly if only a portion of the content is syndicated to other sites, that portion can be marked up as the p-summary.

Test and validate microformats2 markup in general with:

Backward Compatibility

Publisher Compatibility

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

<div class="h-entry hentry">
  <h1 class="p-name entry-title">My great blog post</h1>

Parser Compatibility

Microformats parsers should detect classic properties and parse them as microformats2 properties. If an "h-entry" is found, don't look for an "hentry" on the same element.

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


This work is based on the existing hAtom microformat, and extensive selfdogfooding in the indie web camp community.
