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.
