Coordinating Knowledge in Pervasive Environments

A new application of tuple-space-based coordination systems is in knowledge communication and representation. This knowledge is being published on the Web (the so-called “Semantic Web”) and could be concurrently accessed and used by large numbers of agents distributed across the world, such as in a global pervasive system. Present coordination models assume that the tuples contain plain data, but when knowledge is being coordinated some aspects of coordination systems such as Linda must be revised. In this paper, we focus on the issues of tuple-space views and the ability of agents to perform destructive retrieval of information from the tuple spaces. Knowledge is not something that is universally shared, rather different groups share different views of the world. It is also something that does not cease suddenly to exist, rather it tends to be forgotten as new knowledge replaces it. Hence we introduce the concepts of scoping and fading and describe how this can be applied to supp...
