A semantic agent for xmpp / jabber network which finds and shares content about resources (using RDF/SPARQL) for you and your jabber friends.
The functionality of the perl implementation is the following: First it will listen on a file system FIFO and send every line to the given XMPP/Jabber account(s). Second it will update the XMPP/Jabber presence information every 60 sec. by the latest system load and free memory values. Using syslog-ng it is now easy to send specific system messages to your XMPP/Jabber account :)
