CoMEdiA is a groupware tool which enables co-authors to cooperatively produce hypermedia docu-ments.CoMEdiA allows co-authors to communicate their ideas,drafts,guidelines,constraints and annota-tions to other co-authors.It uses a mix of communication patterns,media and document organization toenable co-authors to keep on exchanging information(remotely or face-to-face),improving passages andmodifying notes until a final document is achieved.We did not concentrate on the depth but on thebreath 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.We be-gan with the text medium and are now including bitmaps and raster images.Later sound and video willalso be integrated.In this paper we describe and sustain the available capacities.
