Description
-----------
Collaborative editing (CE) is an important topic in the area of computer
supported collaborative work (CSCW). Collaborative editing systems (CES)
allow multiple users to edit the same set of documents collaboratively
over the computer networks synchronously or asynchronously. Traditional 
topics include the design and implementation of multi-user text file
editors and graphics editors (e.g. whiteboard). Other document types such
as image, multimedia, hypertext, hypermedia, spreadsheets, 3D models, and 
diagrams are emerging as the target of group editing in recent years. This
category of groupware not only contains useful tools for CSCW but also
serves as an excellent vehicle for exploring a range of fundamental and
challenging issues facing the designers of realtime groupware systems in
general.

As a special type of distributed systems, CESs inherit many technical
challenges which have been actively addressed in the literature of
distributed computing and database systems. However, due to the
omnipresence of human factors, CESs present a unique set of problems and
issues not addressed in traditional distributed systems and single-user
interactive applications. For example, high responsiveness is expected by
a user when he or she is performing local operations. Timely propagation
of user operations across computer networks promotes mutual awareness of
users and user activities. A CES not only needs to maintain consistency 
across different sites but also needs to take into account the original
user intentions i.e. the context of operations. As a collaborative editing
session scales up from LAN to the Internet, those problems aggravate due
to the non-negligible network latencies. Algorithms and techniques (e.g. 
transformation, multi-versioning, optional locking, group undo) proposed  
in CESs can also bring new insights into the design of other distributed  
applications, e.g., Internet-based multi-player games, collaborative  
virtual environments, mobile computing, etc.


Participants
------------
A wide variety of CSCW research areas contribute to collaborative editing
including group awareness, concurrency control, social interaction,
usability and human factors as well as areas such as distributed
computing. Researchers with experience in designing, implementing, or    
intensive use of group editors are especially encouraged to participate. 
One author of each accepted paper is expected to give a 30-minute
presentation. To promote more in-depth discussion in one day, the number
of participants is expected to be less than 20.


Submissions
-----------
In November 1999, we organized a very successful workshop entitled
"Consistency Maintenance and Group Undo in Real-Time Group Editors",
jointly with ACM GROUP'99 Conference on Supporting Group Work. In this
CSCW'2000 workshop, we plan to extend the topics so that more participants
can be brought together from related areas. We invite submissions which
address issues related to collaborative editing. Interesting topics
include but are not limited to the following:

* Concurrency control and consistency maintenance in group editors.
* Usability study of group editors and human factors.
* Social aspects of collaborative editing.
* Application of group editing techniques and algorithms in distributed
  applications.

Electronic submissions (HTML, PDF, PostScript, or MS Word) should be sent 
to [log in to unmask] by email. Each paper is preferably four to eight pages
in length, formatted according to the standard ACM SIGCHI publication
guidelines (http://www.acm.org/sigs/sigchi/chipubform/), and should include
an abstract of no more than 100 words.
