h-feed
This article is a stub. You can help the microformats.org wiki by expanding it.
h-feed is a microformats2 experiment with a top level feed object to contain h-entry posts.
From experience with hAtom, it's not clear that there's actually a need (use-case) for a top level feed, but for those that wish to experiment with it, here it is.
root class name: h-feed
properties:
- p-name - name of the feed
- p-author - author of the feed, optionally embed an h-card Main article: h-card
- u-url - URL of the feed
- u-photo - representative photo / icon for the feed
children:
- nested h-entry objects representing the items of the feed
Use Cases
- 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

- ...
- 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
Converters
- 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>
…
Real world example:
- Sandeep Shetty has marked up his home page, http://sandeep.io/ in this way.
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.
