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”
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)

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

•Quality Control and Provenance (Miller)
•Shipboard Event Logs (Chandler)
