This paper presents a taxonomy of collaborative applications based on the temporal, spatial, and modal dimensions of communication between members of a workgroup. The taxonomy satisfies the characteristics of being concise, sufficiently inclusive, comprehensive, and extendible. The taxonomy can be used to analyze collaborative applications and software. Common collaborative applications and representative software are summarized
