Abstract

The Earth System Science Workbench (ESSW)is a nonintrusive data management infrastructure or 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 or 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 or 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.
