An introduction to the ways XMPP is used by various companies, both as a messaging solution for people and machines.
XMPP Primer
The architecture of XMPP networks will be explained along with comparisons to familiar systems like SMTP. Next, XMPP addresses(JIDs) will be covered. Finally, the basic building blocks of XMPP traffic, the stanzas, will be demonstrated in several contexts, followed by information about how XMPP stanzas are extended.
Installation and Setup of ejabberd
There are many choices possible with ejabberd in regards to database setup, authentication, and deployment. The basic database choices (SQL vs. Mnesia) will be covered along with the typical services in XMPP servers, including Web integration. Logs, debugging, and clustering will also be covered.
Getting Started with exmpp
exmpp is an XMPP client library written in Erlang. It will be used to create some basic XMPP client applications.
ejabberd Architecture
ejabberd is made up of many parts, and understanding these parts will help in building new applications or extensions. The main router, session manager, and the various hooks will all be covered.
Extending ejabberd
ejabberd is easily extended by writing Erlang code. This section covers customizing behavior, including authentication. It will also cover writing new XMPP services, web services, and adding server commands.
