Existing systems supporting collaboration processes typically implement a single, fixed collaboration protocol, and collaboration process takes place inside a single group. In this paper, we present in details the DynG prototype which provides support for multiple collaboration protocols for non-monolithic collaboration processes, i.e. collaboration processes in which collaboration is spread among many groups. Collaboration protocols used by the DynG prototype includes communicative, “acting”, and social aspects of collaboration processes, and the introduction of group actions provides support for group dynamics and helps to structure collaboration processes.
