  1. Semantic Concepts in Expedition Metadata Bob Arko Lamont-Doherty Earth Observatory OOSSI Workshop Nov. 18, 2008

  2. Expedition – • specific science mission to study a specific locale • research platform in motion - operates from specific time/point of departure to return • science party onboard • activities include remote sensing, in situ sampling, instrument deployments • in marine context, typically a “cruise”

  3. Expedition data management – current projects – • Legacy of Ocean Exploration (LOE) • Antarctic Master Directory (AMD) • Extended Continental Shelf (ECS) • Scientific Earth Drilling Information System (SEDIS) • Rolling Deck to Repository (R2R)

  4. R2R pilot project – vision – National Data Centers Fleet Data Portal Research Vessels Data Assembly Centers (SAMOS, MGDS, JASADCP, etc.)

  5. Expedition data model – Collection Expedition Data Set Event Log Data Object (from a sensor or a sampler)

  6. Expedition vocabularies – • Expedition ID • Platform Type+ID • Organization ID • Person ID+Role • Location Type+ID • Device Type+ID • Data Type • Event Type

  7. Expedition vocabulary challenges – • when/how to control values? (e.g. people names) • when/how to adopt or extend community standards? (e.g. extend IHO Gazetteer to local features) • what is a data set? (output of a device? process?)

  8. MMI projects underway – • publish expedition vocabularies at mmisw.org • develop device ontology (case study - scientific sonars)

  9. MMI device ontology – scientific sonars • subtypes (singlebeam, multibeam, subbottom, etc.) • attributes (swath width, freq. range, etc.) • inputs (time/position, motion, sound speed) • outputs (bathymetry, amplitude, sidescan, etc.) • examples

  10. R2R posters at Fall AGU – • Database Infrastructure (Arko) • Quality Control and Provenance (Miller) • Shipboard Event Logs (Chandler) • Thu. PM session IN43A
