Structure Management In The Collaborative Multimedia Editing System Iris

Structure management within collaborative editing systems is an important feature when the editable documents consist of multimedia contents. This becomes even more interesting when the interface between a media-independent structure editor and the media-dependent content editors should be designed. Based on the experiences with our common modeling framework, the newly developed multiuser editor IRIS, this paper describes the design of structure editing and discusses what operations are needed for the media-independent interface of the structure editor. Furthermore, some implications of the chosen approach are shown and a number of recommendations are made for improving our framework.
