Abstract

Consistency maintenance is a critical and challenging issue in many interactive groupware applications that can be modeled as group editors. This paper addresses two open consistency problems: divergence and operation effects relation violation. While the former has been partly solved, the latter has never been addressed in any published work. We propose a novel approach to solving both problems in the same framework. Particularly it preserves the effects relation of concurrent operations so that convergence is achieved automatically. Our work provides a new perspective into group editors and operational transformation algorithms.
