What is GeoSciML
• GeoSciML is an XML-based data standard for exchange of complex geoscientific information
• UML data model • XML markup language
• For complex Web Feature Services (WFS)

What is GeoSciML
• GeoSciML-Portrayal is an XML-based data transfer standard for simple feature geoscience information
– The “baby brother” of GeoSciML
– Allows delivery of a small and very simplified part of the full GeoSciML model
– Can be used for simple features Web Feature Services (WFS) and for Web Map Services (WMS)
– Analogous to a shapefile (GeoSciML-Portrayal) vs a relational geodatabase (GeoSciML)

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 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 evolution
• Geography Markup Language (GML v3.2)
• Observations and Measurements (O&M v2.0)
• Sensor Web Enablement (SWE Common v2.0)
• GeoSciML version 3 uses and extends recently updated OGC and ISO standards, including:
Some elements of GeoSciML v2 were retired in v3 in favour of using existing ISO and OGC standard elements
• eg, use SWE Common to deliver numeric and controlled terminology attributes

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
