Abstract

How do you provide more than 350 scientists and researchers access to data from every instrument in Odyssey when the data is curated across half a dozen institutions and in different formats and is too big to mail on a CD-ROM anymore? The Planetary Data System (PDS) faced this exact question. The solution was to use a metadata-based middleware framework developed by the Object Oriented Data Technology task at NASA's Jet Propulsion Laboratory. Using OODT, PDS provided — for the first time ever — data from all mission instruments through a single system immediately upon data delivery.
