PubSub Tools

Developers can build applications or services on top of pubsub using our XMPP (Jabber) delivery service. By using XMPP, users can get information that matches their subscriptions as soon as it's published.

This page will be our repository for documentation, sample code and information about using the PubSub.com service over XMPP. Check back to see the latest updates to this site. Please note that any use of the PubSub.com service constitutes acceptance of our terms of service.

Documentation
PubSub/XMPP Tutorial and Reference (August 2004)

This document provides a protocol reference and sample transactions for connecting to the PubSub XMPP server.

Sample Applications and Libraries
C# PubSub Protocol Library (BSD License)
C# Sample Client Application (GPL)

Please note: Following a recent protocol update, some XML namespaces have changed in the PubSub XMPP service. Be sure to download the client library version 0.30 or greater to work with the new namespaces. This version of the client library is available on sourceforge.

The C# library is intended for use in developing new PubSub applications or adding PubSub functionality to existing client programs. The sample application (MessageStack) demonstrates how to integrate the PubSub library into a simple client program.

The client library has been tested and is known to work with current versions of Mono/C# on Linux. A simple shell program is provided for testing.
