The Open Geospatial Consortium (OGC) and the OpenMI Association (OpenMI) have released the proposed Open Modelling Interface Version 2 (OpenMI)
standard for public comment. This standard defines a standard apporach for independently developed computer models of environmental processes to exchange data as they run.
The original driver for the standard was the European Water Framework Directive and its requirement for an integrated approach to water management. The European Commission co-funded the research and development of a generic model interface, which is the OpenMI.
The immediate goal is to enable the integrated modelling needed to understand Earth system processes.
Environmental modelling is not the only application of integrated modelling. For example, a possible shorter term application will simply be in enabling developers to convert their existing large, and often unmanageable, applications into sets of linkable components. This could change the modelling market from one for complete systems into one for components and services.
The documents being released for comment can be viewed and downloaded. Comments are due by June 1 2013.
