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

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.

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:


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.
