    1.2 Introduction
    The main purpose of CWM is to enable easy interchange of warehouse and business 
    intelligence metadata between warehouse tools, warehouse platforms and warehouse 
    metadata repositories in distributed heterogeneous environments. CWM is based on 
    three key industry standards:
    • UML - Unified Modeling Language, an OMG modeling standard
    • MOF - Meta Object Facility, an OMG metamodeling and metadata repository 
    standard
    • XMI - XML Metadata Interchange, an OMG metadata interchange standard
    These three standards form the core of the OMG metadata repository architecture as 
    illustrated in Figure 1-1.
    The UML standard defines a rich, object oriented modeling language that is supported 
    by a range of graphical design tools. The MOF standard defines an extensible 
    framework for defining models for metadata, and providing tools with programmatic 
    interfaces to store and access metadata in a repository. The XMI standard allows

    metadata to be interchanged as streams or files with a standard format based on XML. 
    The complete architecture offers a wide range of implementation choices to developers 
    of tools, repositories and object frameworks. XMI in particular lowers the barrier to 
    entry for the use of OMG metadata standards.
    Key aspects of the architecture include:
    • A four layered metamodeling architecture for general purpose manipulation of 
    metadata in distributed object repositories. See the MOF and UML specifications 
    for more details
    • The use of UML notation for representing metamodels and models
    • The use of standard information models (UML) to describe the semantics of object 
    analysis and design models
    • The use of MOF to define and manipulate metamodels programmatically using fine 
    grained CORBA interfaces. This approach leverages the strength of CORBA 
    distributed object infrastructure.
    • The use of XMI for stream based interchange of metadata 
    This specification mainly consists of definitions of metamodels in the following 
    domains:
    • Object model (a subset of UML)
    • CWM foundation
    • Relational data resources
    • Record data resources
    • Multidimensional data resources
    • XML data resources
    • Data transformations
    • OLAP (On-line Analytical Processing)
    • Data mining
    • Information visualization
    • Business nomenclature
    • Warehouse process
    • Warehouse operation
    This specification defines these metamodels and provides proof of concept that covers 
    key aspects of CWM. The specification represents the integration of work currently 
    underway by the submitters and supporters in the areas of warehouse metadata 
    management in distributed object environments. The submitters intend to 
    commercialize the CWM technology within the guidelines of the OMG. 
    The adoption of the UML and MOF specifications in 1997 was a key step forward for 
    the OMG and the industry in terms of achieving consensus on modeling technology 
    and repositories. The adoption of XMI in 1999 reduced the plethora of proprietary
