The OpenMI (Open Modeling Interface) Standard defines an interface that allows models to exchange data in memory at run-time. When the standard is implemented, existing models can be run simultaneously and share information, for instance at each time step, making model integration feasible at the operational level. The OpenMI standard was created with the intent to facilitate model integration, which is helpful in understanding and predicting process interactions and achieving an integrated approach to environmental management. The OpenMI standard is owned and maintained by the OpenMI Association, an open, not for profit group of international organizations and people. On the 1st of July 2014 the Open Geospatial Consortium (OGC®) membership has approved the Open Modelling Interface Standard Version 2 (OpenMI) as an OGC standard. ==OpenMI architecture== OpenMI is based on a ‘request & reply’ mechanism and a pull-based pipe-and-filter architecture, which consists of communicating components (source components and target components) that “exchange memory-based data in a predefined way and in a predefined format”.〔Gregersen, J. B., et al (2007). (“OpenMI: Open Modelling Interface” ). Journal of Hydroinformatics 9(3), 175-191.〕 The OpenMI standard interface has three functions: *''Model Definition'': This allows other linkable components to find out what items a given model can exchange in terms of quantities simulated and the locations at which the quantities are simulated. *''Configuration'': This defines what will be exchanged when two models have been linked for a specific purpose. *''Run-time operation'': This enables the model to accept or provide data at run time.〔(“The OpenMI Document Series, Part A – Scope: For the OpenMI (Version 1.4)” ).
