Enhancements to a digital library web portal for ocean and climate data

The Tasmanian Partnership for Advanced Computing (TPAC) currently hosts a digital library web portal that provides the marine and climate scientific communities with ready access to a large number of heterogeneous and geographically distributed ocean and climate datasets – some huge in scale. The portal uses the OPeNDAP framework for delivery of files. It employs an associated data harvester that crawls new and existing datasets. Metadata is retrieved by the harvester, and made available for search through the digital library web portal. The portal is being enhanced to cater for larger amounts of data, and to provide an increasingly powerful search capability to the scientific community
