Abstract
The coordination of interdependencies between tasks in collaborative environments
is a very important and difficult endeavor. The separation between tasks
and interdependencies allows for the use of different coordination policies
in the same collaborative environment by changing only the coordination
mechanisms that control the interdependencies. This paper presents a framework
for the definition of interdependencies that frequently occur in collaborative
activities. By means of a clear characterization of interdependencies,
it is possible to identify coordination mechanisms to manage them, opening
the way toward a powerful coordination tool capable of encompassing a wide
range of collaborative applications. An implementation of the coordination
model of a collaborative virtual environment based on the proposed framework
is given as example.
