It allows co-authors to communicate their ideas, drafts, guidelines, constraints, and annotations with other co-authors in order to exchange information (remotely or face-to-face), improvepassages and modify notes until a final document is achieved. We did not concentrate on the depth but on the breadth of the features. Our efforts were on integrating and coordinating concepts from collaboration, multimedia, and hyper organization rather than on making a specialized system in any of them. Our first step was to investigate issues in group editing and cooperation. Then we started by having text in our documents, later static images, and 2D-Graphics. This procedure was adopted because we felt these were the most simple media to integrate and process.10.1111/1467-8659.1150309309-322
