ABSTRACT:

This is a talk on the construction of a network of digital libraries for
the hydrology community as part of the CUAHSI Hydrologic Information System (HIS) based on an architecture developed for the publication of oceanographic data acquired by oceanographic research vessels. Our results show that this architecture and implementation are appropriate for a broad range of scientific disciplines and that the approach scales from the desk of the individual investigator to that of a major research institution and to the interoperation of institutions. We are able to run the entire digital library from a laptop computer as well as from supercomputer-center-size resources. The underlying architecture and prototype set of tools have been developed as a part of the SIOExplorer project (http://SIOExplorer.ucsd.edu), funded by National Science Digital Library (NSDL), Information Technology Research (ITR) and Ocean Science (OCE) awards over the last three years. With funding from the NSF Geosciences Directorate, this approach has been adapted to hydrology and is operating in a multi-site configuration representing a network of hydrological observatories and oceanographic archives. The system is integrated with the GEONgrid (http://geongrid.org) and includes automatic methods of harvesting data and metadata from existing web-sites (e.g., USGS
and NASA) as well as real-time and near-real-time sensors through other data systems such as Unidata OpenDAP and Local Data Manager.
