Its creation has been driven by the need to understand how processes interact and to predict the likely outcomes of those interactions under given conditions. A key design aim has been to bring about interoperability between independently developed modelling components, where those components may originate from any discipline or supplier. The ultimate aim is to transform integrated modelling into an operational tool accessible to all and so open up the potential opportunities created by integrated modelling for innovation and wealth creation.<\/p>\n\n\n\n<p>This document defines the requirements that a component must meet to achieve OpenMI compliance. These comprise: 1) a very thin core set of requirements covering the information and functions needed to establish a link and make an exchange between two components and 2) a set of optional extensions for handling more complex situations. The document does not describe how to implement the standard.
