Configuring Apps with the Companion File
This file is XML-based and referred to as the companion file or cfile. The companion file is loaded into the system at the same time as the model and should have a XML file extension.
The full XSD schema of the companion file XML is documented at https://www.fico.com/fico-xpress-optimization/docs/latest/insight5/xml_reference. Examples of companion file markup are provided throughout this guide.
The companion file meta-data can be used to perform a number of important configurations that control the way the system behaves for the app and views. A minimal companion file is given by:
<?xml version=!1.0” encoding=”UTF-8"?>
<model-companion xmlns="http://www.fico.com/xpress/optimization-modeler/model-companion" version="3.1">
</model-companion>
App Names and Versions
On the Home page each app has a preset name and version. On importing an app the name is taken from the Mosel model name and the version is an optional setting in the Mosel file. For example:model "units"
