XMI resources
XMI (XML Metadata Interchange) is a format for exchanging metamodel-based data between different tools. Like UML, XMI is a standard defined by the OMG.
ARIS UML Designer exports and imports XMI files in UML 2.5 / XMI 2.1 format. You can use XSLT files to make corresponding adjustments to XML formats from third-party manufacturers. These XSLT files are managed in the XMI resources area and can be selected as options during the XMI export and import.
