GeoSciML - GeoScience Markup Language

GeoSciML or Geoscience Markup Language is a GML Application Schema that can be used to support interoperability of geologic information served from Geologic Surveys and other data custodians. The emphasis is on "interpreted geology" information that is conventionally portrayed on geologic maps. Its feature-type catalogue includes geologic units, mapped features, geologic structures, as well as earth materials (rocks and unconsolidated materials), and specializations of sampling features from the Observations and Measurements standard such as boreholes and geologic specimens. Supporting resources such as vocabularies for geoscience terminology and timescales are developed in concert with the application schema.

The GeoSciML project was initiated in 2003, under the auspices of the IUGS Commission for the Management and Application of Geoscience Information (CGI) working group on Data Model Collaboration - now the CGI Interoperability Working Group. The development of GeoSciML was strongly influenced by predecessor projects in North America, Europe, Australia and Japan.

GeoSciML is intended to support data portals publishing data for customers, for interchanging data between organisations that use different database implementations and software/systems environments, and in particular, for use in geoscience web services. GeoSciML is currently used by national and international data sharing projects, including the OneGeology project, an effort to create a live geological map of the entire Earth by delivering data from many national geological surveys. It is also used as the geologic data transfer standard by the European Union INSPIRE project, the US Geoscience Information Network, and the Canadian Groundwater Information Network.

GeoSciML Version 3.1 was released in December 2012. In January 2013, a GeoSciML Standards Working Group was initiated in OGC, in collaboration with CGI, to develop a version 4 release as an OGC modular specification. This release will include simple feature 'portrayal' schemes to support interoperable view services.
