GHRC DAAC is nearing completion of a major software infrastructure upgrade. After an extensive test period, we are now using the open source PostGIS database management system (DBMS) and associated services for our local metadata catalog, replacing the legacy Oracle DBMS. A second component of the new infrastructure is the Data Publication Portal (DAPPeR), which provides tools for tracking and partial automation of the data publication workflow, from receipt of a new dataset through metadata generation and documentation to publication. DAPPeR is based on ORNL DAAC’s Semi-automated ingest System (SAuS), and will greatly facilitate GHRC’s data publication processes.
