|The OpenMI Association Newsletter
OpenMI Association is the organisation responsible for the development,
maintenance, and promotion of the Open Modelling Interface (OpenMI).
OpenMI is a standard, which facilitates the linking of simulation models
and model components of environmental and socio-economic processes. It
thus enables managers to more fully understand and predict the likely
impacts of their policies and programmes.
Visit the OpenMI Association web site at www.openmi.org
to learn which models are already OpenMI compliant, get help on OpenMI
model migration, request new features, exchange opinions and provide
feedback related to OpenMI implementations.

|Did you know that...
OpenMI is not a Framework... but can be applied to link frameworks
OpenMI can be used when iterations, time and spatial aggregation, and extrapolations are required
there are How-to pages on the OpenMI-wiki under the Getting Started tab
it takes very little to migrate from OpenMI 1.x to 1.4
Stef Hummel (Deltares) has been appointed OpenMI Compliancy Officer!
|A short history of ZOOMQ3D as an OpenMI compliant model
(a message from Andrew Hughes, Groundwater Modelling Team Leader, British Geological Survey)
I was very happy, and not a little relieved when the
groundwater flow model ZOOMQ3D was officially recognised by the OpenMI
organisation as being OpenMI compliant.
ZOOMQ3D is one of the ZOOM family of object-oriented (OO)
groundwater models. The ZOOM family includes a groundwater flow model,
ZOOMQ3D (e.g. Jackson et al. 2005),
an advective particle tracking model, ZOOPT (e.g. Stuart et
al. 2006) and a distributed recharge model, ZOODRM (e.g. Hughes et al.
We also have developed an OO radial flow model that simulates
flow to wells in r-theta-z co-ordinates (Mansour et al. 2006).
I first encountered OpenMI when I went to a seminar held at
DHI in September 2004.
I left very impressed with the system, which seemed an
appropriate way of solving integrated modelling problems.
As a result of this seminar, BGS made the decision to develop,
test and apply an OpenMI version of ZOOMQ3D.
We have achieved this aim and presented an example as a poster
at ModelCARE 2007 (Cheetham et al., 2007).
We are now working with HR Wallingford to further test the
OpenMI compliant version of ZOOM and are considering making other OO
models in the ZOOM family compliant.

|CSDMS to use OpenMI to build a surface dynamics community
The Community Surface Dynamics Modeling System (CSDMS)
has chosen the OpenMI interface as a central element in the framework
being built. The OpenMI standard will be combined with the Common
Component Architecture (CCA) to provide a platform that runs on a single
PC as well as on supercomputer infrastructure. It is an exciting new
step in the development of the OpenMI standard to investigate together
how well its concepts can be used to harness the computational power of
the largest computers around. While raising very interesting technical
issues, this choice for OpenMI underpins once more the international
recognition for the standard and significantly broadens the range of
models that can be coupled using the OpenMI interface.

|US EPA and integrated modelling
From the 10th - 12th of December 2008, the Council for
Environmental Regulatory Modelling convened a workshop for EPA staff and
the agencies and industries with whom they work with. Its purpose was
to establish support for integrated modeling and build a community of
practice. An additional EPA objective was to establish a collaboration
with the OpenMI Association. EPA will prototype a new design for FRAMES
3, where file transfer is replaced or supplemented by the OpenMI
allowing data exchange on a time step by time step basis.

|OpenMI for climate modelling
In a novel approach to represent the coupling between the
land surface and atmosphere, DHI and DMI (Danish Meteorological
Institute) are exploiting OpenMI technology to link hydrological and
climate models. Modelling the effects of climate change on the
hydrological cycle requires a proper understanding of the water and
energy exchange between the atmosphere and the land surface.
This exchange is a process that can have a significant
impact on the hydrological cycle under a changing climate. OpenMI
provides a practical way of linking the achievements of the
meteorological and hydrological modelling community.

|Birds, bogs and bugs: OpenMI and ecosystem services
The UK Centre for Ecology and Hydrology recently funded a
major initiative to assess how OpenMI can help answer pressing
environmental questions by linking science and scientists from different
domains. The WADES project (Wider Assessment of Drought effects on
Ecosystem Services) will link models of soil hydrology, soil chemistry,
vegetation succession, and biodiversity change, allowing the integrated
assessment of multiple effects. A dynamic niche occupancy approach will
be used to determine changes in the suitability of a habitat for
particular bird and plant species. The project will also develop links
to statistical software, to assess the accuracy and parsimony of
different model combinations. WADES will run from 2009 - 2012, and
involves scientists from CEH, RSPB, Alterra and Bangor University. A PhD
studentship is available. More information can be obtained from the WADES website.
|Making OpenMI spatially aware
and geomorphological modeling is best made inside the coherency of a
spatially enabled framework. This is the idea that drove the C.U.D.A.M.1
of the University of Trento and HydroloGIS2 in the development of the
GIS (Geographic Information System) JGrass3 and its toolkits.
Since 2007 JGrass implements in all its models and tools the
OpenMI interfaces. A Console Engine (The JGrass Console4) has been
developed to link together models the OpenMI way through a scripting
language (Groovy or Beanshell, at the moment) that is then translated
into OpenMI's linkable language for execution. This is a powerful tool
that can be used by the scientific community to quickly create complex
applications. Apart from the Horton Machine toolkit that contains more
than 40 geomorphological and hydrological modules, users can find in
JGrass a semi-distributed hydrological model for peak-flow analysis and
the Shalstab hillslope stability model. Besides, a full hydrological
model is being implemented for the management of water resources, and

|Operational integrated modelling has arrived
The 1st OpenMI LIFE Scheldt workshop was successfully held
in Antwerp on the 25th of November 2008. The LIFE project aims to
demonstrate the applicability of the OpenMI through use on a number of
real-world examples in the Scheldt (BE) and Pinios (GR) river basins.
The event was expertly chaired by Professor Willy Bauwens of the Vrije
Universiteit Brussel who introduced a number of presentations from the
Scheldt basin participants. Over 60 participants from a wide range of
organisations and industries attended the workshop, including
representatives of the project partners and members of the OpenMI
Association and its committees. The day following the workshop, a
training session for the OpenMI end users was held at Aquafin,
Aartselaar (BE). The 1st OpenMI LIFE Scheldt workshop marked the end of
the testing phases of the project, prior to moving on to the

Amidst the wide variety of topics, the OpenMI Association
(OA) convened a paper session on current practical OpenMI applications
and a workshop on the strategy and future of the OpenMI. Although
scheduled at the never enviable last morning of the conference, both the
paper session and the workshop attracted a good audience, including
people from all around the world (America, Europe, Australia).

|OpenMI Association prizes for Innovation, Application, and Publication
2008, one OpenMI prize has been awarded to Peter Schade from the
Bundesanstalt fuer Wasserbau, Germany, for his work presentation on
"OpenMI Compliant Import of Initial and Boundary Data into a Numerical
3D Model". The great appreciation of the prize within the OpenMI
community has led to the Executive Committee's decision to increase the
number of prizes for major contributions to the OpenMI community.
Annually, three prizes are now available:
1. The most innovative contribution to the development of the OpenMI standard or SDK
2. The most important application
3. The best publication based on an OpenMI application
To be able to select the best contributions, it is important
to inform the Association of your accomplishments. Please submit your
accomplishments to the OpenMI Association Dissemination Committee at email@example.com.
