The availability of vast quantities of data through electronic archives hastransformed astronomical research. It has also enabled the creation of newproducts, models and simulations, often from distributed input data and models,that are themselves made electronically available. These products will onlyprovide maximal long-term value to astronomers when accompanied by records oftheir provenance; that is, records of the data and processes used in thecreation of such products. We use the creation of image mosaics with theMontage grid-enabled mosaic engine to emphasize the necessity of provenancemanagement and to understand the science requirements that higher-levelproducts impose on provenance management technologies. We describe experimentswith one technology, the "Provenance Aware Service Oriented Architecture"(PASOA), that stores provenance information at each step in the computation ofa mosaic. The results inform the technical specifications of provenancemanagement systems, including the need for extensible systems built on commonstandards. Finally, we describe examples of provenance management technologyemerging from the fields of geophysics and oceanography that have applicabilityto astronomy applications.
