Leveraging Operational Transformation in Collaborative Object Groups

Collaborative Object Groups are abstractions that facilitate programming of collaborative systems considerably. In this paper, we argue that operational transformation should be offered to programmers as a part of services provided by a Collaborative Object Group platform and describe how to integrate operational transformation in such a platform. We also explain how operational transformation solves well-known problems of collaborative systems, such as latecoming, earlyleaving, coupling/uncoupling, undo/redo and version merging in a generic way.
