Tantek Çelik (Editor)
h-feed is a simple, open format for publishing a stream or feed of h-entry posts, like complete posts on a home page or archive pages, or summaries or other brief lists of posts. h-feed is one of several open microformat draft standards suitable for embedding data in HTML.
h-feed is the microformats2 update to hAtom, and in particular its "hfeed" root class.
Per CC0, to the extent possible under law, the editors have waived all copyright and related or neighboring rights to this work. In addition, as of 2024-04-27, the editors have made this specification available under the Open Web Foundation Agreement Version 1.0.
Properties
h-feed properties, inside an element with class h-feed. All properties are optional.
root class name: h-feed
Core Properties
The following core h-feed properties have broad consensus:
p-name- name of the feedp-author- author of the feed, optionally embed an h-cardMain article: h-cardu-url- URL of the feedu-photo- representative photo / icon for the feed
children:
- nested h-entry objects representing the items of the feed
Draft Properties
None currently.
Proposed Properties
The following properties are proposed additions based on various observed examples in the wild, but are awaiting at least one reader / real world consuming code example to become a draft property:
p-summary- based on non-trivial actual content usage of "atom:subtitle" on Blogger and WordPress.com featured blogs's Atom feeds.p-entry- to be more consistent with the cascading of p-author or p-comment.
Status
h-feed is a microformats.org draft specification. Public discussion on h-feed takes place on h-entry-feedback and the #microformats irc channel on irc.freenode.net.
h-feed is ready to use and implemented in the wild, but for backwards compatibility you should also mark h-feed up as a classic hAtom "hfeed".
Use Cases
- Named feeds
- IndieWeb Readers are consuming home page feeds marked up with h-feed and using the name of the h-feed in their user interfce.
- Generate an Atom feed
- This seems like a legacy use-case, not sufficient to actually justify h-feed.
- Feed per channel of content - needs a name
- "I will have a feed per tag (channel) so I want to name them." - Sandeep Shetty in #indiewebcamp
- It appears there is some desire to create separate feeds for an indieweb site for separate subsets of content, and name them explicitly accordingly. This presents a need for a container object for the h-entry elements, where the container itself can have a name. This is a potential interesting use-case for an explicit 'h-feed'.
Examples in the wild
Add any examples in the wild that you find to the top of this list.
- ...
- http://sandeep.io/ uses h-feed with p-name and p-author properties and child h-entry posts. In particular using h-feed on the <html> element allows using p-name on the <title> element and re-using the visible window title of the HTML page as the name of the feed, neatly avoiding a DRY violation.
- http://tantek.com/ uses h-feed with p-name and p-author properties and child h-entry posts.
Implementations
Readers
- Woodwind
- Shrewdness
- http://notenoughneon.com/feed.php (404 as of 2017-05-29)
Proxies
- Bridgy
Converters
- unmung - will transform an RSS or Atom feed into an h-feed containing h-entries,
- microformats to RSS - a Yahoo! pipe that converts a URL containing an h-feed containing h-entries, into an RSS feed. (2013-10-21 blog post announcing)
Parsing
When parsing a page for an h-feed, do so per microformats2.
Fallback:
If there is no explicit "h-feed" element, implementations may:
- Treat the
<title>of the page or the URL of the page as the p-name - Use http://indiewebcamp.com/authorship to discover authorship of posts.
- Treat top level h-entry elements as items in the feed.
FAQ
How do I avoid duplicating the page title
I want to use the name (title) of my page as the name of my feed, how do I avoid duplicating the page title somewhere invisibly on the page as the feed name?
If you want re-use the <title> of your page as the name of your feed, you can do so by putting the h-feed root class name on the <html> element, and the p-name property class name on the <title> element, e.g. here's a snippet showing how those tags would look:
<html class="h-feed">
…
<title class="p-name">sandeep.io</title>
…
What should a subscriber do with a page with multiple feeds
What do I do when a user subscribes to a URL with multiple distinct h-feeds?
A feed reader should subscribe to the first h-feed it finds at a URL.
