GeoSciML
IUGS Commission for Geoscience Information
Geological surveys + other agencies needs:
Efficiently exchange and publish archived data in re-usable form
Support single Point-of-Truth
GeoSciML v1.1
GML Application schema for Geology
Based on conceptual information models from USGS/GSC/BGS/CSIRO
2006 testbed - 8 geological surveys, 6 countries
On-demand from survey datastores, converted into GeoSciML at source, delivered using OGC WFS & WMS

AUKEGGS
Support for Earth Science research
Esp. fluid-earth sciences
Focussed on reconciling “Grid” (Globus, WS-XX) and Open Geospatial Consortium approaches
Grid strengths: Coordination and chaining, AAA, stateful services, high-volume, high-performance
OGC strengths: Rich interoperability, with strong community semantics, through rigorous content models, registries
Outcomes:
NERC NDC uses OGC combo with Globus and WS-XX for workflows
Engagement with WMO
Development of best practices in relation to GML + Coverage data + non-XML data sources
Improvement of best practices in standardizing metadata profiles
Community building
