Introduction to XMPP protocol and developing online collaboration applications using open source software and libraries

Extensible Messaging and Presence Protocol (XMPP) is an open, XML-based protocol aimed at near-real-time, extensible instant messaging (IM) and presence information. It has been expanded into the broader realm of message-oriented middleware. Built to be extensible, the protocol has been extended with features such as Voice over IP and file transfer signaling. XMPP protocol has been used by many social networking platforms including gtalk, and facebook; collaborative services like google wave, and gradient; geo-presence systems like Nokia Ovi Contacts; multiplayer games like chesspark, and by many online live customer support and technical support services. In this manuscript, I will introduce XMPP and its extensions. In the tutorials I will demonstrate how you can leverage some of the available open source software and libraries for rapid development of XMPP enabled services and communication platforms. The tutorial slides and supplementary materials will be available on my website: http://drozturk.com/talks.
