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

Organization, funding and futures

AUKEGGS

Academic/research focus

UK NERC funds for travel, meetings

Follow-ups as opportunity arises

GeoSciML

Statutory custodian focus

Participating orgs support own staff through existing projects

No $ for collaboration & project management

Operational systems Issues with governance and version control

Futures:

2008 Testbed for IGC
