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

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

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