COCA (Collaborative Objects Coordination Architecture) was proposed as a novel means to model and support collaborations over the Internet. Our approach separates coordination policies from user interfaces and the policies are speci ed in a logic-based language. Over the past year, both the collaboration model and the speci cation language have been substantially re ned and evaluated through ou...
