ABSTRACT 

Computer-supported cooperative work, or CSCW, is an emerging area of 
both research and commercial interest which is concerned with the use 
of computers to support and enhance the work activities of groups. 
Collaborative applications are notoriously hard to build however.  As 
Grudin says, "the design process fails because [developers'] intuitions 
are poor for multi-user applications." 

A number of characteristics of collaborative applications contribute to 
their intractability.  These include the multi-user nature of such 
systems (requiring application developers to maintain serialization and 
synchronization among multiple event streams), the requirement for 
fine-grained access control, the need for flexible session management, 
and the potentially distributed nature of collaborative applications. 

The goal of this proposed research is create a framework to enable the 
easier creation of robust, flexible, multi-user collaborative 
applications.  I believe that it is possible to draw a distinction 
between two classes of information sharing in collaborative 
applications, and that by drawing such a distinction it is possible to 
gain insight into ways to support collaborative systems both at 
development time and run-time.  These two sharing classes are 
application information sharing and meta-information sharing. 
Application information sharing is the "classical" form of sharing and 
involves sharing application-internal data in a collaborative session. 
Meta-information sharing is the sharing of information used to 
facilitate the process of collaboration itself; it is the sharing of 
information used by the underlying collaboration support environment. 

I hypothesize that by drawing this distinction and focusing on various 
aspects of meta-information sharing, it will be possible to 
significantly enhance the development process and run-time flexibility 
of collaborative applications.  In this talk I shall discuss the 
distinction in types of sharing and explain why I have focused on this 
one type of information sharing.  I will specifically examine four 
specific objectives of this research which involve the sharing of 
meta-information:  session management, user representations in a 
collaborative system, policy expression, and modality transitions 
between synchronous and asynchronous collaboration.

spin surf or spin punk.  Undetected, we are both, or might be neither.
