Does ArgoUML save XMI files?
Yes. ArgoUML versions through 0.18.1 will export XMI 1.0 files containing models conforming to the UML 1.3 metamodel. Beginning with ArgoUML 0.20, XMI 1.2 files are exported conforming to the UML 1.4 metamodel. XMI files can be exported separately and they are also included in the zipped .zargo file where they can be extracted using the ‘jar’ command.
