Start date: Jun 1, 2010, End date: May 31, 2013 PROJECT  FINISHED 

Designed to route information between computers, the Internet is evolving into an Internet of services, media and "things" (devices and other "Real World Objects" connected to or tracked via the Internet). In this new Internet, the main interest is no longer on machines but on items of "content". Today, users locate and access content via servers (e.g. search engines) that connect them to the machines where it is physically stored. CONVERGENCE aims at enhancing the Internet with a content-centric, publish-subscribe service model, based on a common container for any kind of digital data, including representations of people and Real World Objects. This common container, named Versatile Digital Item (VDI), is a "package" of digital information with a unique identifier, independent of the machine where the VDI is hosted. VDIs will be designed to handle all possible kinds of digital information, from media to information about services, people and physical objects, independently of the structure or geographical location of the content. The CONVERGENCE architecture will provide scalable mechanisms allowing professional providers and individual users to publish and subscribe to VDIs, maintain access to VDIs when they move from one host to another; search for VDIs, as well as updating and deleting VDIs which have already been published. CONVERGENCE will allow both professional providers and consumers to define their own policies for authenticating and protecting VDIs and supporting "digital forgetting" (ensuring that VDIs are deleted when they pass a user-defined expiry date). CONVERGENCE will test its proposal in two "tracks" dedicated respectively to real-life business scenarios and to network experimentation using large scale facilities. The framework proposed by CONVERGENCE will be proposed to relevant standardization bodies. Software developed in the project (including middleware and applications) will be made available to the Open Source community.
