The Specific Model Input and Output Configuration (SMIOC)

The Specific Model Input and Output Configuration (SMIOC) specifies the relations the component model will establish at run time with the external environment through inputs and outputs for a specific run. It must be generated by the user for each component model based on the corresponding PMIOD information, either by hand or with the graphical user interface oasis-gui.tcl available in oasis4/util/gui.

The SMIOC Schema is given in oasis4/util/xmlfiles/smioc.xsd. The SMIOC file name must be $<$application_local_name$>$_$<$component_local_name$>$_smioc.xml where
$<$application_local_name$>$ is the application `local_name´ attribute and $<$component_local_name$>$ is the component `local_name' attribute in the scc.xml file. Examples of SMIOC xml files for the toy coupled model TOYOA4 can be found in oasis4/examples/toyoa4/input.

The SMIOC may contain 3 types of information detailed in the next paragraphs:

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

Part of this information is used to define attributes of the I/O NetCDF files but is not mandatory for the proper execution of the coupled model per se; if it is not specified in the SMIOC, it will just be missing in the I/O files. In the paragraphs below, it is detailed which information is mandatory and which is not.
