29 November 2012. The Open Geospatial Consortium (OGC)
invites participation in a Groundwater Interoperability Experiment (GWIE2).
This activity, which began on 23 October 2012, will develop
and test the candidate OGC Groundwater Markup Language (GWML) 2 standard by
harmonizing and advancing existing initiatives such as GWML1, the EU-INSPIRE
effort, GeoSciML, and others. Participants will then prepare an engineering
report with the intent to develop it into a data encoding specification that
will be advanced toward adoption as the OGC Groundwater Markup Language 2 (GWML
2) Standard. This activity is being carried out within the Hydrology Domain
Working Group, which operates under the auspices of the OGC and the World
GWML 2 will meet the requirements for a human-readable and
machine-readable transfer standard for groundwater feature data, including data
about water wells, aquifers, and related entities. GWML 2 will also serve as a
reference for hydrological observations related to these features. (See the OGC WaterML2.0 Encoding
The OGC members that are acting as initiators of the
Interoperability Experiment are:
Scientific and Industrial Research Organisation (CSIRO)
Resources Canada (NRCan)
Geological Survey (USGS)
A summary of the activity plan, requirements for
participation, schedule, and kick-off meeting details are available at: http://external.opengeospatial.org/twiki_public/HydrologyDWG/GroundwaterInteroperabilityExperiment2.
Expressions of interest for participation
are due by 27 December 2012.

OGC testbeds, pilot projects and interoperability
experiments are part of the OGC's Interoperability Program, a global, hands-on
collaborative prototyping program designed to rapidly develop, test and deliver
proven candidate specifications into the OGC's Standards Program, where they
are formalized for public release. These initiatives enable users and providers
of geospatial technology to share the costs of developing standards that
provide a foundation for "future-proof" enterprise architectures.
Providers reduce their costs of developing and maintaining interfaces and
encodings while gaining industry recognition, the confidence of an initiative's
sponsoring organizations, and the market growth that results from open
An OGC Interoperability Experiment is a rapid, low overhead,
formally structured OGC-facilitated activity in which members achieve specific
technical objectives that further the OGC Technical Baseline.
The OGC® is an international consortium of more than 470
companies, government agencies, research organizations, and universities
participating in a consensus process to develop publicly available geospatial
standards. OGC Standards empower technology developers to make geospatial
information and services accessible and useful with any application that needs
to be geospatially enabled. Visit the OGC website at
