Managing dynamic metadata as context

Abstract

As the amount of metadata describing services and their access frequencies increased in P2P/Grid Computing Environments, there is an emerging need for Information Services to make such metadata available. The metadata describing services might include frequently changing information, so it presents a dynamic behavior. We use context as metadata to capture such frequently changing dynamic information. Here, context information can be used not only for discovering services, but also by services after they have been discovered. In this paper, we are interested in providing and managing context information parts of which is likely to be changed very frequently. We describe our initial efforts in building Fault Tolerant and High Performance Information Systems (FTHPIS) to make both dynamic and static context information available
