OGC ® A Brief History 2003, Edinburgh –first international meeting held to begin harmonisation of geological data models developed in North America, Europe, and Australia –seed of the IUGS Commission for Geoscience Information (CGI) –several precursor projects were considered, including the North American Data Model (NADM) the Australian Exploration and Mining Markup Language (XMML) the Multi-Lingual Thesaurus of Geology 2004, Ottawa & Florence CGI launched and its Interoperability Working Group (IWG) was formed –IWG would be the vehicle for GeoSciML development for the next 8 years GeoSciML - The History and Future of an International Geoscience Data Transfer Standard, St Petersburg, June 2013

OGC ® A Brief History 2004, Perth –first official meeting of the IWG GeoSciML Task Group 2005, Ottawa –GeoSciML version , Orleans, Liege & Brussels 2007, Tucson & Melbourne –GeoSciML version , Orleans, Uppsala & Oslo 2009, Quebec 2010, Rome 2011, Edinburgh 2012, Wellington –GeoSciML version GeoSciML - The History and Future of an International Geoscience Data Transfer Standard, St Petersburg, June 2013

OGC ® A Brief History January 2013, Redlands, Open Geospatial Consortium (OGC) –Memorandum of Understanding signed between CGI and OGC –first meeting of the GeoSciML Standards Working Group under OGC GeoSciML will now be developed, documented and published within the OGC standards framework –using OGC standards specifications –with the imprimatur of an established multi-domain spatial standards organisation GeoSciML - The History and Future of an International Geoscience Data Transfer Standard, St Petersburg, June 2013

OGC ® GeoSciML evolution Version 1 –geological units –contacts –geological structures –earth materials –geological age –geological feature relations –physical properties for structures only –timescale –vocabularies Version 2 additions –updates to geological units, events/age, earth materials, physical properties –added boreholes, fossils Version 3 –repackaged the model into 13 separate schema modules –updates to geological units, feature relations, events/age, physical properties, boreholes –added geomorphological units, alteration, geological sampling, laboratory analyses –changed the way that vocabularies and controlled terminology were handled GeoSciML - The History and Future of an International Geoscience Data Transfer Standard, St Petersburg, June 2013

OGC ® GeoSciML after Version 3 User feedback indicated that the GeoSciML model and its many application schemas was too complicated to implement for new users with relatively simple data –an unfortunate consequence of trying model a highly complex scientific domain Strategy #1 - GeoSciML-Portrayal –develop a simplified data standard that could deliver a small core of GeoSciML using simple features WFS or WMS with a minimum of controlled terminology –geological units, contacts, faults, borehole collars –retained some controlled terminology to enable standard symbolisation of geological features (eg, using SLD for WMS) –Version 2 published in 2013 GeoSciML - The History and Future of an International Geoscience Data Transfer Standard, St Petersburg, June 2013

OGC ® The Future - GeoSciML v4 Strategy #2 - GeoSciML v4 –re-organise GeoSciML v3 to enable users to deliver all the core features of GeoSciML using one (or very few) XML application schemas –these core features would satisfy the majority of use cases asked by geologists of digital data. eg; “show me the geological units which contain shale” “show me the geological units of Permian age” “show me where the thrust faults are” –more complicated and less commonly used features, attributes and relationships are delivered by using extension schemas –work in progress –for discussion here in St Petersburg GeoSciML - The History and Future of an International Geoscience Data Transfer Standard, St Petersburg, June 2013
