XML Metadata Interchange (XMI) is a standard of the Object Management Group (OMG) and is increasingly used as an exchange format between software development tools (e.g. in the Eclipse Modeling Framework , EMF).

The format is open and vendor-neutral and allows the data exchange of objects on the basis of meta-metamodels according to the Meta Object Facility (MOF). In addition to UML models, any metadata can be exchanged as long as it can be expressed using the MOF . Due to the XML format, corresponding files can easily be created, searched, processed, saved and transmitted over the Internet. In this regard, XMI is superior to alternative exchange formats such as CDIF .

example

<xmi:XMI version="2.0" xmlns:UML=" http://schema.omg.org/spec/UML/1.4" 
xmlns:xmi=" http://schema.omg.org/spec/XMI/2.0">
    <xmi:Metamodel name="UML" version="1.4" href="UML.xml"/>
    <xmi:Model name="example" version="1" href="example.xml"/>
    <UML:Class name="C1">
        <feature xmi:type="UML:Attribute" name="a1" visibility="private"/>
    </UML:Class>
</xmi:XMI>
