Distributed groupware systems provide computer support for manipulating objects such as a
text document or a filesystem, shared by two or more geographically separated users. Data …

Group editors allow a group of distributed human users to edit a shared multimedia
document at the same time over a computer network. Consistency control in this …

The operational transformation (OT) approach, used in many collaborative editors, allows a
group of users to concurrently update replicas of a shared object and exchange their …

In distributed collaborative systems, replicated objects, shared by users, are subject to
concurrency constraints. All methods [4, 13, 18, 15, 16, 19, 22] proposed to serialize …

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 …

This paper describes algorithms for implementing a high-level programming model for
synchronous distributed groupware applications. In this model, several application data …

In collaborative editing, consistency maintenance of the copies of shared data is a critical
issue. In the last decade, operational transformation (OT) approach revealed as a suitable …

The Operational Transformation (OT) approach, used in many collaborative editors, allows a
group of users to concurrently update replicas of a shared object and exchange their …

Consistency maintenance is one of the most significant challenges in the design and
implementation of the systems, where a group of users is allowed to view and edit the same …

Nowadays, a large number of collaborative editing applications have been developed.
Some of them are deployed on the cloud such as Google Drive and Microsoft Office at …
