A novel event-based consistency model for supporting collaborative cyberinfrastructure based scientific research

Grid computing is an emerging technology one of whose main focuses is the coordinated resource sharing among dynamic groups of individuals, institutions and resources. In collaborative Grid environments, data and system consistency play a crucial role for the correct functioning of the system. In this paper we propose a novel event-based consistency model and discuss the implementation and integration of this model with Semantic Research Grid (SRG)-a collaborative system consisting of tools and services for supporting Cyberinfrastructure based scientific research. Our consistency model is based on the concept of event and dataset; it prevents the replication of records in the system and ensures the working of the system in a consistent state.
