A Web Services based system for data grid

Abstract. In this paper an architecture for a data brokerage service will be proposed. The brokerage service is a part of the system that is being implemented within the European Grid for Solar Observations (EGSO) to provide a high-performance infrastructure for solar applications. A broker interacts with providers and consumers in order to build a profile of both parties. In particular, the broker interacts with providers in order to gather information on the data potentially available to consumers, and with the consumers in order to identify the set of providers that are most likely to satisfy specific data needs.
