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 Work-bench'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 ND-WORM 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.
