PubSubHubbub
IMPORTANT NOTE: The PubSubHubbub protocol has now been adopted by the W3C as a Candidate Recommendation. It's also been renamed WebSub for clarity and concision. Please consider upgrading all older PubSubHubbub implementations to WebSub.
PubSubHubbub is an open protocol for distributed publish/subscribe communication on the Internet. It generalizes the concept of webhooks
and allows data producers and data consumers to work in a decoupled way.
PubSubHubbub provides a way to subscribe, unsubscribe and receive updates from a resource, whether it's an RSS or Atom feed or any web accessible document (JSON...).
The current version of the spec is 0.4. Please, read it here.
Open hubs are provided by:
- Superfeedr
- Aaron Parecki: p3k
- Christian Weiske: phubb
Several other publishing platforms, like Wordpress, include their own hubs.
