EarthResourceML Background
• Information Model for Exchange - Australian Mines Atlas
• Scenarios- deliver data to Australian Mines Atlas- mineralisation investigation over an exploration lease- land use planning to aid land use decisions.- a mine site hazard study- examine mineral system potential
• Governance- Australian Government Geologists Information
Committee (GGIC)- Mineral Occurrence Task Group- Extension of GeoSciML
• Demonstration

EarthResourceML Scenarios
• an explorer conducts an investigation of mineralisation over an exploration lease
• a land use planner investigates potential resources within an area to aid land use decisions.
• a mining engineer conducts a mine site hazard study
• a project generation geologist examines mineral system potential
• deliver mineral occurrence data to the Australian geoscience mineral occurrence portal (Mines Atlas)
EarthResourceML Governance
• Australian/NZ Government Geologists Information Committee (GGIC)
• Commenced work in November 2006
• MineralOccurrences v1.0 released March 2007
• EarthResourceML v1.1 released July 2009
• Production services by GSV, PIRSA, MRT, GSWA, NTGS
• Consumed by AuScope Portal (http://portal.auscope.org/gmap.html)
• Proposed INSPIRE standard (December 2009)
• CGI-IUGS requested to take-over governance (August 2010)
Methodology
• Lessons learnt from GeoSciML development:- No right or wrong way, just agreed way- Use UML to capture model- Don’t maintain classes you don’t have to- Re-use other domain classes (GeoSciML, GML)
• Identify Use Cases from Scenarios- Required for testing
• Community standard data model - an ‘Application schema’- In a serialized form used for data transfer (i.e. ‘standard exchange format’)In general this is different from the storage format
• GoalOne normative artefact – the UML modelDocumentation generated automatically‘How to’ and ‘Cookbook’ documentation
• Map users data to model – modify model if necessary
• Establish WFS – modify model if necessary

Key points
• Describes Earth Resources independent of human activities
NiS mineral occurrence
• Caters for description of Mineral Occurrences using:
Mineral Deposit Models (e.g. remobilised NiS) Mineral Systems (Geodynamic context) Crustal processes
• Utilises GeoSciML ‣Mapped Feature to describe spatial representation‣Earth Material to describe host and associated materials
