CGI Data Model Collaboration

Welcome to the home of SEEGrid.CGIModel.

This is a web-based collaboration area for the IUGS Commission for Geoscience Information, working group on Interoperability.


The Commission for the Management and Application of Geoscience Information (CGI) is a commission of the International Union of Geological Sciences. The aims of CGI are to enable the global exchange of knowledge about geoscience information and systems. It is increasingly becoming important to query and exchange geological information between geological data providers for legal, social, environmental and geoscientific reasons.


CGI and Interoperability

The specific objectives of the CGI Interoperability Working Group are to:
  • to develop a conceptual model of geoscientific information drawing on existing data models
  • to implement an agreed subset of this model in an agreed schema language
  • implement an XML/GML encoding of the model subset
  • develop a testbed to illustrate the potential of the data model for interchange
  • identify areas that require standardised classifications in order to enable interchange


The GeoSciML data model is now developed within the GeoSciML Standards Working Group of the Open Geospatial Consortium (OGC), under a cooperative agreement with the CGI.

Activity of the Interoperability Working Group was historically focussed in six task-groups detailed here:

The CGI Datamodel was initiated at an ad-hoc meeting of interested parties held at BGS, Edinburgh, November 2003.
