| We describe a new collaborative technology
that bridges the gap between ad hoc collaboration in email and
more formal collaboration in structured shared workspaces. Our
approach is based on the notion of object-centric sharing, where
users collaborate in a lightweight manner but aggregate and
organize different types of shared artifacts into semi-structured
activities with dynamic membership, hierarchical object
relationships, as well as real-time and asynchronous
collaboration. We present a working prototype that implements
object-centric sharing on the basis of a replicated peer-to-peer
architecture. In order to keep replicated data consistent in such
a dynamic environment with blended synchronous and asynchronous
collaboration, we designed appropriate consistency control
algorithms, which we describe in detail. The performance of our
approach is demonstrated by means of simulation
results. |
