Adaptive Distribution Support for Co-authored Documents on the Web

In order to facilitate and improve collaboration among co-authors, working in the Web environment, documents must be made seamlessly available to them. Web documents may contain multimedia resources, whose management raises important issues due to the constraints and limits imposed by Web technology. This paper proposes an adaptive support for distributing shared Web documents and multimedia resources across authoring group sites. Our goal is to provide an efficient use of costly Web resources. Distribution is based on the current arrangement of the participating sites, the roles granted to the co-authors and the site capabilities. We formalize key concepts to ensure that system's properties are fulfilled under the specified conditions and to characterize distribution at a given moment. The proposed support has been integrated into the PINAS platform, which allows an authoring group to collaboratively and consistently produce shared Web documents.
