I have been thinking of instant messaging and presence technology in Smallworold from long time. With lot of searching I found XMPP
The protocol is for extensible instant messaging, presence information.. The presence technology has wide usages.
XMPP provides lot of advantages when compared with conventional SOAP Services. (See the table)
The current video demonstration has three parts… a web client, a XMPP server running in Google cloud and a Magik XMPP service running in Smallworld session.
XMPP Magik service is combination of magik + java Smack API.. its a open source client library for instant messaging and presence
The demo is sample example of how we can use xmpp, butt is usage is only limited by the imagination of developer.
