13. GeoSciML: Enabling the exchange of geological map data DEPARTMENT OF PRIMARY INDUSTRIES GeoSciML: a geoscience exchange language November 2003  15 countries represented  established the CGI-IUGS working group  created three task groups: Activities: Data Model Working Group Data Interchange Task Group: develop the schema Testbed Task Group: test the schema Vocabulary Task Group: identify classifications

14. GeoSciML: Enabling the exchange of geological map data DEPARTMENT OF PRIMARY INDUSTRIES GeoSciML: a geoscience exchange language  reviewed existing models  defined initial scope  geological units, earth materials, structures, boreholes  demonstrated Testbed 1 – sharing boreholes  initiated Testbed 2 – sharing geological maps  finalised GeoSciML 1.1  identified required classifications Activities: Data Model Working Group

15. GeoSciML: Enabling the exchange of geological map data DEPARTMENT OF PRIMARY INDUSTRIES GeoSciML: a geoscience exchange language Participants Canada, USA, UK, France, Australia, Sweden Use cases  display map, query one feature, return attributes in GeoSciML  query several map features, return GeoSciML file for download  reclassify map features based on GeoSciML GeologicAge or Lithology Activities: Testbed 2
