New generation of telecommunication services aims at achieving a customization and intelligent information management. Furthermore, most of these services are inherently collaborative. Developing this kind of services requires a middleware which can support intelligent information management in a decoupled and flexible way. This paper presents Triplespaces, a communication and coordination semantic middleware for the development of services based on persistent publication of information. Triplespaces manage information represented in RDF, supporting Web service standards. The authors motivate its benefits to develop new generation telecommunication services.
