Web 2.0 has become the ubiquitous platform for publishing, sharing and linking of content. While users are empowered to create and manage their data, the latter is still scattered and controlled by distributed and heterogeneous Web applications. The data is usually stored in internal silos and is only partially exposed through platform APIs. As a result, the reuse possibilities, fine-grained access control and maintenance of distributed data pieces become a time-consuming and costly activity, if feasible at all. In this paper, we introduce our approach to develop Web applications based on the principles of data portability, decentralization and user-defined access control. Our main contributions are (1) a novel Web service-based storage solution for the read-write Web, combined with (2) a security framework for WebID authentication and authorization based on WebAccessControl lists (WAC), and (3) a corresponding systematic approach for Web applications development based on loosely-coupled and user-controlled storage solutions.
