OpenMI systems can be considered software systems that combine a set of OpenMI- compliant components, possibly in addition to non-OpenMI-compliant components. Such a system can deploy and run OpenMI components by accessing them through their standard interface. The system howevrhowever, also needs to be able to locate and instate instantiate the openMI component properly. For that purpose, the OMI file has been defined.
An OpenMI component can be defined through its OMI file. This The OpenMI file is an XML file which contains sufficient information to identify a component, instantiate the binary unit on your machine (i.e. find the assembly and the class to instantiate) and populate it with input data. An XML schema definition has been created to enable default tools to parse the information.
In principle, OMI files can reside anywhere on your system. Users are therefore free to organize their own repository, as long as they can find the relevant OMI files themselves when configuring their model combination.
An example OMI file is given in Figure 1. The underlying schema definition (XSD) is provided in Figure 2 and 3.
