OGC®

A Brief History

• In the beginning… 2003, Edinburgh

• first 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 data models were considered, includingo the North American Data Model (NADM)

o the Australian Exploration and Mining Markup Language (XMML)

o the Multi-Lingual Thesaurus of Geology

o and others…

• 2004, Ottawa & Florence

• CGI was launched and the Interoperability Working Group (IWG) formed

o IWG would be the vehicle for GeoSciML development for the next 8 years


OGC®

A Brief History

• 2004, Pertho first official meeting of the IWG GeoSciML

Task Group

• 2005, Ottawao GeoSciML version 1

• 2006, Orleans, Liege & Brussels

• 2007, Tucson & Melbourneo GeoSciML version 2

• 2008, Orleans, Uppsala & Oslo

• 2009, Quebec

• 2010, Rome

• 2011, Edinburgh

• 2012, Wellingtono GeoSciML version 3

• 2013, Redlands & St Petersburg

• 2014, Tucson

OGC®

The Move to OGC


• January 2013, Redlands, OGC TC meeting

o Memorandum of Understanding signed between CGI and OGC

o first meeting of the GeoSciML Standards Working Group under OGC

o bound by OGC documentation specifications

o the imprimatur of an established multi-domain spatial standards organisation

OGC®

GeoSciML - the early days

• Original use case for GeoSciML version 1

• describe and exchange features found on a typical geological map geological units

o including hierarchy, relationships

geological structures

o contacts, faults, folds

geological age earth materials


OGC®

GeoSciML evolution

• Version 2

• updates to the v1 data model for:o geological unitso geological events/ageo earth materialso physical properties

• added:o boreholeso fossils

• Version 3

• repackaged the model into 13 separate schema modules

• updates to the data model for: o geological unitso feature relationso events/ageo physical propertieso boreholes

• added: o geomorphological unitso alterationo geological samplingo laboratory analysis metadata


OGC®

GeoSciML evolution

GeoSciML v3 changes, continued -

• used and extended new OGC and ISO standards, including:

o Geography Markup Language (GML v3.2)

o Observations and Measurements (O&M v2.0)

o Sensor Web Enablement (SWE Common v2.0)

• GeoSciML v2 elements were retired in v3 in favour of using existing OGC and ISO standards

o eg, used SWE Common to deliver numeric and controlled

terminology attributes

• geoscience vocabularies are managed outside of the GeoSciML data modelo vocabulary terms encoded using a “byReference/xlink”

pattern to enable links to vocabulary services


OGC®

GeoSciML v3 problems

• User feedback indicated that the GeoSciML v3 model was too complicated to implement for the majority of users who had only relatively simple data

o delivery of even simple geological data required understanding half a

dozen different schemas and delivery of a lot of unnecessary empty

XML elements

o the complex conceptual data model was theoretically correct, but was

not implemented in a sufficiently user-friendly way to attract users

Internal model dependencies

GeoSciML v3.2

OGC®

The Solution

Strategy #1 - GeoSciML-Portrayal

• a simplified data standard that can deliver a small subset of GeoSciML using simple features WFS or WMS on a map with a minimum of data requirements or controlled terminology

• Version 2.0.1 was published in July 2013

o geological units, contacts, faults, borehole collars

• retained a little controlled terminology to enable standard query and symbolisation of map features (eg, using SLD)

• currently implemented by several major map data sharing initiatives, including:

o OneGeology

o USGIN

o AuScope


OGC®

GeoSciML Portrayal

Strategy #1 continued - GeoSciML-Portrayal

• the new version of GeoSciML-Portrayal has simple feature map schemas for:o geological units

o geomorphological units

o faults and shears

o contacts

o boreholes

o geological specimens

o site observations

• an introductory, easy to implement, entry point for users of GeoSciMLo designed to be compatible with the widest possible range of client and

server software applications


OGC®

The Solution

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

• core schema would satisfy the majority of use cases asked by geologists of digital data

o satisfy requirements of key major users of complex features like INSPIRE

o 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


OGC®

The Solution

Strategy #2 continued - GeoSciML v4

• remove mandatory nature of most properties

o removes the need for data providers to deliver many unpopulated XML elements

o enables “profiling” of the GeoSciML standard for different purposes

• use Schematron to control different community profiles of GeoSciML

o INSPIRE and other regional communities; soil and other geological sub-disciplines

o XSD schema validation on its own cannot ensure interoperability

o Schematron can used to validate not only data structure, but also data content

• eg; test the use of agreed vocabularies

o makes GeoSciML potentially more attractive to more user communities
