==== Scope ====

  : //This International Standard provides the basis for metamodel definition in OMG’s family of MDA languages and is based on a simplification of UML2’s class modeling capabilities. In addition to providing the means for metamodel definition, it adds core capabilities for model management in general, including Identifiers, a simple generic Tag capability and
Reflective operations are defined generically and can be applied regardless of the metamodel.//

  : //MOF 2 Core is built on other OMG MOF specifications, in cluding the following (in this list ‘MOF based model’ means any model that instantiates a metamodel defined using MOF, which includes metamodels themselves)://
    * //XMI - for interchanging MOF-based models in XML [XMI25]//
    * //MOF 2 Facility and Object Lifecycle - for connecting to and managing collections of MOF-based model elements [MOFFOL] //
    * //MOF 2 Versioning and Development Lifecycle - for managing versions and configurations of MOF-based models [MOFVD] //
    * //MOF Queries Views and Transformations - for transforming MOF-based models [QVT]//
    * //MOF Models to Text - for generating text, such as programs, from MOF-based models [MOFM2T]//
    * //Object Constraint Language - for specifying constraints on MOF-based models [OCL]//
