The Viopolis project follows a new approach to the long term preservation of citizens' cultural experiences and provides new business models for e-business and end users. The system allows citizen-uploaded and metadata-enriched cultural content from mobile devices to be preserved, distributed and redistributed through a network of commercial and non-commercial Preservation Services. At the same time, it ensures a lasting relationship between content holders and rights' owners. The project infrastructure is based on mobile and Web technologies for content acquisition and builds on cloud storage and content-based retrieval services.
