History of OpenMI

OpenMI (stands for Open Modeling Interface and Environment) is a Standard for model linkage in the water domain

HarmonITIn 2001 the European Commission funded (under the Fifth Framework Programme) a research project named HarmonIT in order to develop and implement a European Open Modeling Interface that would simplify the linking of Hydrology related models. This need was called for in the Water Framework Directive (WFD) that identified whole catchment modeling as a key part of integrated water management.


OpenMITo further promote the use and dissemination of this tool, the HarmonIT project established the OpenMI Association which opened the way to companies, public organisations and universities interested in system analysis and modelling to contribute successfully in the development of the OpenMI Standard Interface.


Four years later, OpenMI-Life Programme was launched (under the LIFE-Programme) by the European Commission aiming at implementing the thematic component LIFE-Enviroment under the policy area "Sustainable management of ground water and surface water management".

The long term aim is that the OpenMI should become the European and global standard for model linking in the environmental domain
