Group editors allow a distributed group of users to collaboratively edit shared documents such as source code and web pages. As a well-accepted consistency control method in group editors, operational transformation (OT) is intuitively believed to be able to preserve operation intentions. However, intention preservation as a consistency constraint has not been rigorously formalized, making it difficult to design OT algorithms and prove their correctness. This work proposes a formalization of intention preservation and analyzes several OT-based approaches to achieving it.
