Earth System Science Workbench: A Data Management Infrastructure for Earth Science Products

The Earth System Science Workbench (ESSW) is a nonintrusive data management infrastructure for researchers who must also be data publishers. An implementation of ESSW to track the processing of locally received satellite imagery is presented, demonstrating the Workbench’s transparent and robust support for archiving and publishing data products. ESSW features a Lab Notebook metadata service, a No Duplicate-Write Once Read Many (ND-WORM) storage service, and Web user interface tools. The Lab Notebook logs processes (experiments) and their relationships via a custom API to XML documents stored in a relational database. The NDWORM provides a managed storage archive for the Lab Notebook by keeping unique file digests and namespace metadata, also in a relational database. ESSW Notebook tools allow product searching and ordering, and file and metadata management.
