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 metadata 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="5.1">
</model-companion>
|
Note: The XML schema version specified by the companion file also determines the version of the
Xpress Insight annotations that are available. Therefore, it is important to use the latest companion file schema version (currently
5.1).

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"
