PowerDesigner supports the import and export of XML Metadata Interchange (XMI) UML v2.x files, an open format that allows you to transfer UML models between different tools. All of the OOM objects can be imported and exported.
Importing XMI Files
PowerDesigner supports the import of an OOM from an XMI file. Since XMI only supports the transfer of objects, PowerDesigner assigns default symbols to imported objects and assigns them to default diagrams.
Exporting XMI Files
PowerDesigner supports the export of an OOM to an XMI file. Since XMI only supports the transfer of objects, any associated PowerDesigner symbols and diagrams are not preserved during the export.
