Group Editer Using Graphical Operational Transformation

Collaborative editing enables multiple users who reside remotely to share and edit some documents at the same time. It is fundamentally based on operational transformation which adjusts the position of operation according to the transformed execution order. For a last decade, many researches have been performed in this area and the correctness and possibility of operational transformation have been proved. In this paper, a novel operation transformation framework is developed to overcome the weakness of existing system. Based on a concept called “operation effects relation,” in which two criteria are defined, causality preservation and operation effects relation preservation and establishes a novel operation transformation framework for developing OT algorithms and proving their correctness for graphical data sharing and editing. In the existing system there is a novel solution for editing and sharing of textual data only. But this paper proves the correctness of textual as well as graphical data sharing and editing using graphical operational transformation algorithm.
