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

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
