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)

    “It is while we are young that the habit of industry is formed. If not then, it never is afterwards. The fortune of our lives therefore depends on employing well the short period of our youth.”
    —Thomas Jefferson (1743–1826)

    “The home is a woman’s natural background.... From the beginning I tried to have the policy of the store reflect as nearly as it was possible in the commercial world, those standards of comfort and grace which are apparent in a lovely home.”
    —Hortense Odlum (1892–?)
