Based on three years of user feedback, a design team at IRIS embarked on a project to enhance Intermedia to better support small groups of collaborators, particularly those involved with document review and revision. Towards this end, we defined user-level requirements for the new functionality. The result of this process was the design and implementation of InterNote. One aspect of InterNote involves a fundamental extension to Intermedia’s navigational linking paradigm. Instead of simply being able to traverse links, users are now also able to transfer data across the links using a technique we call warm linking. In this paper we describe extensions to our hypermedia framework to support annotative collaboration, including the user interface of the new linking functionality and the InterNote extension. Finally, we discuss our plans for future work. I.
