A photo management system for future home environments

In future home environments, users will have access to their digital assets on any device in any room. Home environments will have a high degree of hardware, middleware, software and administrative heterogeneity. Current protocols and systems do not address the consistency problem of mobile data in heterogeneous environments. When data are distributed and duplicated, their logical identities are lost. We propose the introduction of logical identities of mobile data and idcntitypreserving data exchange. We designed the Universal Resource Access Protocol (URAP) and validated it in the MemorySafe system, an experimental photo management system for future home environments. In this paper, we present the proposed concepts and the URAP protocol. We show how they are used to address the consistency problem of mobile data in the MemorySafe system
