Notification servers for synchronous groupware

John F. Patterson, Mark Day, Jakov Kucan
1996 Proceedings of the 1996 ACM conference on Computer supported cooperative work - CSCW '96  
We introduce the Notification Service Transfer Protocol (NSTP), which provides a simple, common service for sharing state in synchronous multi-user applications.  ...  A Notification Server provides items of shared state to a collection of clients and notifies the clients whenever one of the items changes.  ...  We were aiming for a "lean, mean, notification machine" that could be used in a wide variety of synchronous groupware applications.  ...

Engineering plug-in software components to support collaborative work

J. Grundy, J. Hosking
2002 Software, Practice & Experience  
Most approaches hard-code such facilities into applications, with fixed functionality and limited ability to reuse groupware implementations.  ...  Many software applications require co-operative work support, including collaborative editing, group awareness, versioning, messaging and automated notification and coordination agents.  ...  Such facilities include support for both synchronous and asynchronous editing of documents; group awareness facilities; annotation and versioning of documents; messaging, email and chat; change notification  ...

Efficient distributed implementation of semi-replicated synchronous groupware

T. C. Nicholas Graham, Tore Urnes, Roy Nejabi
1996 Proceedings of the 9th annual ACM symposium on User interface software and technology - UIST '96  
The Model View Controller (MVC) architecture has proven to be an effective way of organizing synchronous groupware applications.  ...  The three optimizations, caching, request prefetch and request presend identify communication patterns typical of groupware, and provide optimal behaviour for those patterns.  ...  We would like to thank Jim Cordy of Queen's University at Kingston and Saul Greenberg of the University of Calgary for the use of their equipment in the experiments described in this paper.  ...

Powermeeting on common ground

Weigang Wang
2008 Proceedings of the hypertext 2008 workshop on Collaboration and collective intelligence - WebScience '08  
The Web has been widely used as a platform for asynchronous collaboration. However, Web based synchronous groupware are still rare, especially those using standard Web browser as frontend.  ...  The objective of this work is to make the creation and adoption of such groupware easier, so as to make synchronous collaboration an integral part of collaboration support on the Web.  ...  Such basic polling technique has been used by some early Web applications that need a notification from the server.  ...

Improving Awareness in Mobile CSCW

C. Papadopoulos
2006 IEEE Transactions on Mobile Computing  
We elaborate in particular on synchronous CSCW and expose with it significant details of group awareness, while we contribute a protocol for awareness support over large areas that strikes a balance between  ...  energy consumption and notification time.  ...  Groupware Services The next layer in our implementation is another reflective module that implements groupware services, which include notification and synchronization, session management, and data sharing  ...

Mobile Support in CSCW Applications and Groupware Development Frameworks

David Johnson
2013 International Journal of Interactive Mobile Technologies  
This paper reviews seminal and state-of-the-art cooperative software applications and development frameworks, and their support for mobile devices.  ...  Some of these challenges are inherent to the nature of the device hardware, while others focus on the understanding of how to engineer software to maximize effectiveness for the end-users.  ...  The Web server also acts as a server for Java clients that provided a rich UI to the shared workspaces.  ...

In the context of expressing concurrency control in groupware systems, the paper shows how a specification of temporal properties of the semi-replicated groupware architecture can be refined to three different  ...  This refinement approach helps in understanding the temporal properties of groupware applications, and increases confidence in the correctness of their implementation.  ...  In synchronous groupware applications, it is not only important to capture how components may communicate, but when.  ...
