Achieving convergence, causality preservation, and intention preservation in real-time cooperative editing systems
TLDR
A consistency model, with properties of convergence, causality preservation, and intention preservation, is proposed as a framework for consistency maintenance in real-time cooperative editing systems. Expand

  • 1 October 2009
TLDR
In this paper, we analyze the limitation of the causality theory, propose a novel theory of operation context as the new foundation for OT systems, and present a new OT algorithm-Context-based OT (COT)-which provides uniform and efficient solutions to both consistency maintenance and undo problems.

Transparent adaptation of single-user applications for multi-user real-time collaboration
TLDR
We report an innovative Transparent Adaptation (TA) approach and associated supporting techniques that can be used to convert existing and new single-user applications into collaborative ones, without changing the source code of the original application. Expand

Consistency maintenance in real-time collaborative graphics editing systems
TLDR
We propose an object-level multiversioning approach to consistency maintenance in real-time collaborative graphic editors that preserves the work concurrently produced by multiple users in the face of conflict, and in minimizing the number of object versions for conflict resolution. Expand
