The XML Metadata Interchange (XMI) is an Object Management Group (OMG) standard for exchanging metadata information via Extensible Markup Language (XML).

It can be used for any metadata whose metamodel can be expressed in Meta-Object Facility (MOF), a platform-independent model (PIM).

The most common use of XMI is as an interchange format for UML models, although it can also be used for serialization of models of other languages (metamodels).
