Research in collaborative editing tends to have been undertaken in isolation rather than as part of a general information or application infrastructure. Our goal is to develop a universal information platform that can support collaboration in a range of application domains. Since not all user groups have the same conventions and not all tasks have the same(More)
Nowadays, real-time editing systems are catching on. Tools such as Etherpad or Google Docs enable multiple authors at dispersed locations to collaboratively write shared documents. In such systems, a replication mechanism is required to ensure consistency when merging concurrent changes performed on the same document. Current editing systems make use of(More)
Awareness of the activities of other users and also document evolution is an important part of collaborative authoring. We introduce the concept of an editing profile that can be used to maintain and visualise measures of the changes made across a document by different users in both synchronous and asynchronous collaborative editing. It provides a simple(More)
Wikis, a popular tool for sharing knowledge, are basically collaborative editing systems. However, existing Wiki systems offer limited support for co-operative authoring, and they do not scale well, because they are based on a centralised architecture. This paper compares the well-known centralised MediaWiki system with several peer-to-peer approaches to(More)
In the recent years, due to the emergence of new models of production based on collaboration, collaborative writing tools started to be increasingly used by various communities. Due to great variety of groupware software, there is the need of criteria for discriminating the working modes supported by these tools. In this paper we propose a new model for the(More)
Since the Web 2.0 era, the Internet is a huge content editing place in which users contribute to the content they browse. Users do not just edit the content but they collaborate on this content. Such shared content can be edited by thousands of people. However, current consistency maintenance algorithms seem not to be adapted to massive collaborative(More)
Version control systems are widely used to support a group of people working together on a set of documents over a network by merging their changes into the same source repository. The existing versioning systems offer limited support concerning conflict resolution and tracking of user activity. In this paper we propose a multi-level editing approach that(More)
Collaborative editing enables a group of people to edit documents collaboratively over a computer network. Customisation of the collaborative environment to different subcommunities of users at different points in time is an important issue. The model of the document is an important factor in achieving customisation. We have chosen a tree representation(More)
