PubSubHub in ODS
PubSubHub (PSH) setup consists of two steps:
- Set up the ODS server.
- Configure applications to publish to hub.
These steps are detailed below.
The following packages should be installed:
Set up the ODS server
PSH setup on the ODS Server takes two steps, performed while logged in as the
- In the Feed Instances with Admin Rights section , specify the PSH endpoint.

(You may command-click to select multiple notification targets.)
- Click Add to make your setting take effect.
Test the setup using ODS-Feed Manager and basic PSH Subscription UI
For our test, we use ODS-Weblog as publisher and ODS-Feed Manager as subscriber.
First, in ODS-Feed Manager we subscribe to the rss feed:
- Log in as a normal user, e.g.,
- Go to the Feed Manager application.
- Go to Administration -> Feeds and click Subscribe.
- Select From URL... and click Next.
- In From URL (RSS/Atom/OPML/OCS/SIOC ...) field, enter the Weblog Feed URL, e.g.,
- Click Subscribe
- The PSH Server value will be shown, and PubSubHub? Enable will be checked.
Click Subscribe again.
Now, we publish something on the 'dav' weblog:
Notification is made to the PSH endpoint, and the Feed Manager is notified to update its subscription content.
