The Potential Model Input and Output Description (PMIOD)

The Potential Model Input and Output Description (PMIOD) describes the relations a component model is potentially able to establish with the external environment through inputs and outputs. There should be one PMIOD per component model, written by the component developer, either by hand or with the graphical user interface wizard.tcl available in oasis4/util/gui, to describe its component potential coupling interface, but the PMIOD files are not used by the OASIS4 coupler.

The PMIOD Schema is given oasis4/util/xmlfiles/pmiod.xsd. The PMIOD file name should be $<$application_local_name$>$_$<$component_local_name$>$_pmiod.xml where $<$application_local_name$>$ is the application name and $<$component_local_name$>$ is the component name. Examples of PMIOD xml files for the toy coupled model TOYOA4 can be found in
oasis4/examples/toyoa4/input.

The PMIOD contains 3 types of information:

• general characteristics of the component
• information on the grids
• information on the coupling/IO fields, also called `transient variables'
