Web 2.0 data: decoupling ownership from provision

Current Internet trends have caused us to outgrow existing online data storage paradigms. This paper presents an extended model for distributed online data storage. The model addresses issues of data duplication, data freshness and data ownership, while facilitating two modes of data access - direct and indirect. Direct data access is implemented using advanced handoff techniques while indirect access is implemented using robust server-to-server protocols that enforce strict policies on data management. Results are presented that compare this solution to existing technologies and an example migration path is described for existing Web 2.0 applications wishing to adopt this new paradigm.
