XML Metadata Interchange - Integration of Industry Standards

Integration of Industry Standards

XMI integrates four industry standards:

  • XML – Extensible Markup Language, a W3C standard.
  • UML – Unified Modeling Language, an OMG modeling standard.
  • MOF – Meta Object Facility, an OMG language for specifying metamodels.
  • MOF – Mapping to XMI

The integration of these four standards into XMI allows tool developers of distributed systems to share object models and other metadata.

Several versions of XMI have been created: 1.0, 1.1, 1.2, 2.0 and 2.1. The 2.x versions are radically different from the 1.x series. The version 2.1.1 was issued in December 2007.

There are now other XML standards for representing metadata. One of the most recent is the Web Ontology Language (OWL) (but ontologies are a very specialized kind of metadata, and OWL has no built-in support for most of the information represented in UML). OWL is built upon the Resource Description Framework (RDF).

XMI is now an international standard:

ISO/IEC 19503:2005 Information technology – XML Metadata Interchange (XMI)

    “No delusion is greater than the notion that method and industry can make up for lack of mother-wit, either in science or in practical life.”

    “The standards of His Majesty’s taste made all those ladies who aspired to his favour, and who were near the Statutable size, strain and swell themselves, like the frogs in the fable, to rival and bulk and dignity of the ox. Some succeeded, and others burst.”
    —Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
