Last minute as usual.


Here's the abstract I submitted on GeoSciML v3 for AGU:


CONTROL ID: 1211423

TITLE: GeoSciML version 3: A GML application for geologic information


CURRENT SECTION/FOCUS GROUP: Earth and Space Science Informatics (IN)

CURRENT SESSION: IN25. Real Use of Open Standards and Technologies

Management and Application of G Intl. Union Geological Sciences1

ABSTRACT BODY: After 2 years of testing and development, XML schema for
GeoSciML version 3 are now ready for application deployment. GeoSciML draws
from many geoscience data modelling efforts to establish a common suite of
feature types to represent information associated with geologic maps
(materials, structures, and geologic units) and observations including
structure data, samples, and chemical analyses. After extensive testing and
use case analysis, in December 2008 the CGI Interoperability Working Group
(IWG) released GeoSciML 2.0 as an application schema for basic geological
information. GeoSciML 2.0 is in use to deliver geologic data by the
OneGeology Europe portal, the Geological Survey of Canada Groundwater
Information Network (wet GIN), and the Auscope Mineral Resources portal.
GeoSciML to version 3.0 is updated to OGC Geography Markup Language v3.2,
re-engineered patterns for association of element values with controlled
vocabulary concepts, incorporation of ISO19156 Observation and Measurement
constructs for representing numeric and categorical values and for
representing analytical data, incorporation of EarthResourceML to represent
mineral occurrences and mines, incorporation of the GeoTime model to
represent GSSP and stratigraphic time scale, and refactoring of the GeoSciML
namespace to follow emerging ISO practices for decoupling of dependencies
between standardized namespaces. These changes will make it easier for data
providers to link to standard vocabulary and registry services. The depth
and breadth of GeoSciML remains largely unchanged, covering the
representation of geologic units, earth materials and geologic structures.
ISO19156 elements and patterns are used to represent sampling features such
as boreholes and rock samples, as well as geochemical and geochronologic
measurements. Geologic structures include shear displacement structures
(brittle faults and ductile shears), contacts, folds, foliations, lineations
and structures with no preferred orientation (e.g. 'miarolitic cavities').
The Earth material package allows for the description of both individual
components, such as minerals, and compound materials, such as rocks or
unconsolidated materials. Provision is made for alteration, weathering,
metamorphism, particle geometry, fabric, and petrophysical descriptions.
Mapped features describe the shape of the geological features using standard
GML geometries, such as polygons, lines, points or 3D volumes. Geological
events provide the age, process and environment of formation of geological
features. The Earth Resource section includes features to represent mineral
occurrences and mines and associated human activities independently. This
addition allows description of resources and reserves that can comply with
national and internationally accepted reporting codes. GeoSciML v3 is under
consideration as the data model for INSPIRE annex 2 geologic reporting in
