Designing an interoperable infrastructure for synchronous collaboration

The use of synchronous groupware offers to collaborators similar advantages than face to face meeting. Regarding the design of systems of this kind, the most accurate middleware is the use of messages oriented middleware (MOM). One of the current issues which affects also to collaborative environments is interoperability. More concretely, the use of web service standards has gained its prominence in this area. The use of WS-Eventing and WS-Notification seem to be the most accurate specification for the building of interoperable MOM systems. The aim of this paper is to offer the design and implementation of an interoperable synchronous architecture for the delivery of messages between applications developed in different programming languages devoted to text-based tools, such as instant messaging and chat.
