4. Purpose Semantic Interoperability with GeoSciML
Map Visualization: “Sandstone” = Blue
Data Query: Get “Sandstones” in N. America
Data Download: USA Lithology = “Sandstone”
CAD Lithology = “Sandstone”

5. Approach Vocabulary = concepts + terms (ontology) (ideas) (language)
Concept: ‘sandstone’
Term: “sandstone” (EN), “grès” (FR), “arenaria” (IT)

6. Approach Definition: using properties, e.g. ‘sandstone’:
geneticCategory = ‘sedimentary’
particleType = ‘grain’
grainSize = ‘fine-grained’ OR ‘phaneritic’
consolidationDegree = ‘consolidated’

7. Plan Compile terms needed for GeoSciML
Identify key concepts, definitions, relations
Assign multi-lingual terms to concepts*
Place online as GeoSciML vocabulary
Recommend governance structure
Solicit feedback

8. Recommended Usage Data Query: mandatory Data Download: optional
Map Visualization: ?

9. Status 42 vocabularies identified
22 draft vocabularies proposed (mainly EN)
including Lithology and Time Scale
20 in progress (due Nov 2008)
Help us draft & review defs, and add terms!
