Abstract

. This paper proposes a framework for distributed data management in collaborative computing systems. The Collaborative Computing Data Space (CCDS) is a user-level tool that provides a group of participants with a space of shared data objects, as well as a simple interface to operations on data objects in the data space. ?

Typical services provided by collaborative computing systems include common displays, multimedia conferencing applications, and (quasi-)transparent access to remote devices and computational resources. Underlying this shared environment is a data management subsystem that supports the reliable sharing of distributed data objects among collaborators. Colla...
