During the last years, the asset costs for storage have been decreasing continuously. Coincidentally, the demand to create and publish data in the Web has grown in an unprecedented manner. Within the Web 2.0, the user became an active part by creating, publishing, changing and annotating data and its related metadata in a wide variety of new kinds of applications. Many data management but also architectural decisions for such applications are driven by distribution and semantic aspects. In this paper, we present how the WebComposition data grid service (WebComposition/DGS) emerges new kinds of data-centric applications as a REST-architectural style component within the context of Web 2.0 but also satisfies requirements within traditional SOA-based business scenarios.
