Projects

4/2007 - 6/2009

The objective of the ExpeShare project is to facilitate multimedia content and experience sharing, support for building and managing mobile virtual communities as well as enable converged multimedia services for communities over peer-to-peer networks.

In ExpeShare project, MediaTeam researches new technologies for capturing and sharing experiences in mobile peer communities. The project also studies the technologies of Web 2.0 and mash-ups that combine content and services from various sources. The aim of the project is to take the peer-to-peer networking paradigm to the mobile world and enhance the provided services with the advantages of the Web 2.0. The work becomes concrete with a service architecture that is created for the development, testing and introduction of new technologies and experience sharing services. Special attention is also paid to the management of content rights and understanding of the associated value chains and market structures.

In the project, demonstrative prototype services are created to evaluate the developed technologies and the service architecture. Prototypes are empirically evaluated by conducting field trials in real-life settings and with real end users.

International project consortium consists of business partners from Finland, France, Spain and Italy.

MediaTeam's ExpeShare project is a part of the pan-European ITEA 2 program.
