Subject RE: Stomp Topic
Date Tue, 25 Jan 2011 10:14:41 GMT

Oups,

In fact, it's in RadioVis specification (cf http://radiodns.org/wp-content/uploads/2009/12/RVIS01_1.0.0.pdf)
which use STOMP. 

Maybe it will help somebody working on it.

Thanks for your time

Best regards

Michael

semantics of the destination names is not defined by the Stomp
