The process of collaborative authoring of Web content may be supported by resource repositories which provide storage facilities as well as certain value-added services. However, since specific demands posed by the authoring process may vary according to special characteristics of such a process, resource repositories with predefined services usually address these demands only to a limited extent. To overcome this problem, we propose a way of generating customized repositories for collaborative authoring of Web content. Our approach involves a set of frameworks that can be adapted and applied to the specification of repository services in order to generate customized repositories with services tailored to the requirements of the authoring process.
