Methodology• Lessons learnt from GeoSciML development:

– No right or wrong way, just agreed way– Use UML to capture all– Don’t maintain classes you don’t have to– Re-use other domain (GeoSciML, GML) classes where possible– Re-use patterns

• Identify Use Cases from Scenarios– This part is rarely done well!– Required for testing

• Interoperable communities share a language– Community standard data model– This may be formalized as an ‘Application schema’– In a serialized form (file format) this is used for data transfer (i.e. ‘standard exchange

format’)– In general this is different from the storage format

• Goal– One normative artefact – the UML model– Everything must either be in the model or the rules for converting from model to schema– Software and documentation generated automatically– ‘How to’ and ‘Cookbook’ documentation

• Map users data to model – modify model if necessary• Establish WFS – modify model if necessary

Documentation

• Based on other international standards• Extension of GML:

– GM_Object– TM_Instant– TM_Period

• O&M:– SpatialReferenceFrame

• MD_Metadata:– CI_Citation

• GeoSciML:– GeologicFeature– MappedFeature– GeologicAge– EarthMaterial– CGI_Value

• Real-world objects classified into types based on a characteristic set of properties

Key points

• Describes Earth 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

• Requires use of controlled vocabularies

Key points cont.

• Utilises GeoSciML Mapped Feature to describe spatial representation

• Utilises GeoSciML Earth Material to describe host and associated materials

Future work

• Model needs the Mineral Systems part developed Source: melt composition, physical properties, metal endowment Pathways: propagation, complexity, flow regime Traps: efficiency, periodicity, scale

• Cleanup
