h-entry is a simple, open format for content on the web which can be syndicated, primarily but not limited to blog posts. h-entry is one of several open microformat draft standards suitable for embedding data in HTML/HTML5.

h-entry is the microformats-2 replacement for hAtom.

Example

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>
  </div>
</article>

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

Properties

h-entry properties (inside class h-entry):

• p-name - entry name/title
• p-summary - short entry summary
• e-content - full content of the entry
• dt-published - when the entry was published
• dt-updated - when the entry was updated
• p-author - who wrote the entry, optionally nested h-card(s)
• p-category - entry categories/tags
• u-url - entry permalink URL
• u-uid - unique entry ID
• p-geo - geophysical location the entry was posted from, optionally a nested h-geo
• p-latitude - decimal latitude
• p-longitude - decimal longitude
• p-altitude - decimal altitude

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

• u-in-reply-to - the URL which the h-entry is considered a reply to or comment on.
  • Potentially optionally a nested h-entry (for reply contexts) but I’m the only one doing that right now so not considered a recommendation --bw 16:44, 13 June 2013 (UTC)
• p-comment - optionally nested h-entry(ies), each of which is a comment on/reply to the parent h-entry. See comment-brainstorming.

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

• u-photo
• u-audio - consider special u- parsing rules for <audio>
• u-video - consider special u- parsing rules for <video>
• u-in-reply-to - for links to other posts that this post is a reply to (comment regarding, etc.)

Status

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.

FAQ

• 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.

Examples in the wild

Real world in the wild examples:

• ... add uses of h-entry you see in the wild here.
• SemPress is a WordPress theme that supports h-card, h-feed/h-entry.
• The Pastry Box Project use h-card and h-entry markup on their homepage and individual thoughts pages
• Aaron Parecki uses h-entry to mark up notes, e.g. 2012/230/reply/1.
• Tantek Çelik uses h-entry on his home page, as well as h-entry on all post permalinks, e.g. 2012-243 post, with rel-prev/rel-next (if applicable) to indicate prev/next posts
• Barnaby Walters uses h-entry on all notes and articles, as well as nested within notes as reply contexts example and comments example.

Background

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