چکیده انگلیسی:
HydroShare (https://www.hydroshare.org) is an online collaborative system to support the open sharing
of hydrologic data, analytical tools, and computer models. Hydrologic data and models are often large,
extending to multi-gigabyte or terabyte scale, and as a result, the scalability of centralized data man
agement poses challenges for a system such as HydroShare. A distributed data management framework
that enables distributed physical data storage and management in multiple locations thus becomes a
necessity. We use the iRODS (Integrated Rule-Oriented Data System) data grid middleware as the
distributed data storage and management back end in HydroShare. iRODS provides a unified virtual file
system for distributed physical storages in multiple locations and enables data federation across
geographically dispersed institutions around the world. In this paper, we describe the iRODS-based
distributed data management approaches implemented in HydroShare to provide a practical demon
stration of a production system for supporting big data in the environmental sciences.
