Originally conceived as a "Network of hosts", the Internet is evolving into an Internet of services, an Internet of media, an Internet of people and an Internet of "Things". This implies a strategic shift from "Host-centric" to "Content-centric" and "Data-centric" networking. CONVERGENCE proposes to enhance the Internet with a novel, information-centric, publish-subscribe service model, based on the Versatile Digital Item (VDI): a common container for all kinds of digital content, derived from the MPEG-21 standard. Results in terms of standardization activities and software implementation are presented.
