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]
