Scientific Data IntegrationScientific Data Integration ... Questions to Queries ...... Questions to Queries ...

What is the distribution and U/ Pb zircon ages of A-type plutons in VA? How about their 3-D geometry ?

How does it relate to host rock structures?

• Uploadable:Uploadable:– OWL ontologies

– OWL inter-ontology mappings (“articulations”)

– Data sets (shape files)

• ““Semantic Registration”Semantic Registration”– Link data set D with ontology O1

(w/ instance-based heuristic)

– Query D using ontology O2

– (e.g. rock classification: O1= GSC, O2=BGS)
