Workflow Libraries

There are a number of current libraries that allow you to quickly and easily build out the subscriber or publishers pieces of the PubSubHubbub workflow.

Subscriber clients

These subscriber clients will allow you to subscribe a site or service, via the hub, to a feed from the publisher:

• .NET: http://code.google.com/p/npubsubhubbub/

• Haskell: http://hackage.haskell.org/package/pubsub-0.10

• Java: http://code.google.com/p/pubsubhubbub-java/downloads/

• PHP: http://github.com/lxbarth/PuSHSubscriber

• Ruby on Rails: http://github.com/empika/Superfeedr-PubSubHubbub-Rails-Plugin

• Scala: http://github.com/kafecho/scala-push

For more information on the subscribers and alternative frameworks and CMS systems, visit http://code.google.com/p/pubsubhubbub/wiki/SubscriberClients.
