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

2. Semantic Concepts in Expedition Metadata 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. Semantic Concepts in Expedition Metadata 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. Semantic Concepts in Expedition Metadata Fleet Data Portal Data Assembly Centers (SAMOS, MGDS, JASADCP, etc.) National Data Centers Research Vessels R2R pilot project – vision –

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

6. Semantic Concepts in Expedition Metadata Expedition vocabularies – Expedition ID Platform Type+ID Organization ID Person ID+Role Location Type+ID Device Type+ID Data Type Event Type

7. Semantic Concepts in Expedition Metadata 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. Semantic Concepts in Expedition Metadata MMI projects underway – publish expedition vocabularies at mmisw.org develop device ontology (case study - scientific sonars)

9. Semantic Concepts in Expedition Metadata 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
