Good tutorials on XMPP? [closed]

Question

I've been looking at some open-source XMPP servers, and am familiar with the official page http://xmpp.org/. But thus far I've not found anything in between "The Extensible Messaging and Presence Protocol (XMPP) is an open technology for real-time communication" and a list of XEP specifications. For instance articles explaining the basics and terminology - stanzas, IQ, presence, etc, etc. Even the Wikipedia page misses this, unsurprisingly the open-source projects assume you know these things before you start digging into the code.

Is there a good, (semi-)official set of tutorials on this? Do I need to be looking for Jabber resources rather than XMPP?

Amongst other things, I'd hope to see diagrams for use-cases and flow, not just dry protocol text. I know books on XMPP exist, but generally anything in a book is available in some form online too.

Answer 1

This is probably way too basic, but at least it's technical: https://web.archive.org/web/20170916193014/http://www.adarshr.com/fun-with-xmpp-and-google-talk and the second part, https://web.archive.org/web/20171005104211/http://www.adarshr.com:80/fun-with-xmpp-and-google-talk-part-2

It explains what stanzas are, what types are available and stuff.

Answer 2

Here is what got me startet on XMPP Development:

• A good book: XMPP The Definivie Guide
• A mature Java API. I've chosen the Smack Library from Ignite Realtime and used the groovy language with a buch of small scripts to learn the basics.

Later i developed a plugin for the OpenFire XMPP Server. There are some tutorials and a forum on their site as well. I think that both the smack and the openfire api's are easy to learn.

If you are not into java: The book referes to the SkeekXMPP Python library and it uses it to create some examples (echo bot, ...).
