Abstract

Collaborative editing refers to the editing groups which produce work products as the collection of individual contribution. We present an implementation model on how to increase fault tolerance for collaborative editing systems with fickle operations. Some of the recent research revealed that collaborative editing systems were constructed by the Conflict free Replicated Data Types (CRDT). This new approach is shown to avoid the fault on the every user’s replicas updates that should not affect the owner’s document. Every user can update their own document with some updates. At the end, all the updates were transferred to the owner’s original document. In some case some of the user’s replica can update with some mismatch updates that can also be reflected on the owner’s document. So these updates badly reduce the reliability and integrity of the collaborative systems. The mismatch updates and the faults cause the whole document lead to lessen its integrity and quality. In this paper, we carefully analyze, find the mismatch updates and the replica’s faults towards this type of systems and reduce the fault tolerance. We define algorithms to find such fault mismatch and remove that fault replica. Then we produce the original document without any fault updates.
