The aim of this work is to design and then implement a Configuration Repository for a grid-based Problem Solving Environment (PSE), specialized to describe applications and data belonging to the remote sensing field. In a distributed environment the information system plays a central role in order to enhance scheduling algorithms and, more generally, to address grid-aware application requirements. Taking into account that the grid is inherently dynamic, i.e. machine load and availability, network latency and bandwidth change continually, we present the design of a Configuration Repository for retrieving, storing and handling information. In particular, the proposed solution has been designed having in mind all of the specific characteristics belonging to the remote sensing systems.
