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 that are defined generically and can be applied regardless of metamodel.

MOF 2 Core is built on by other OMG MOF specifications, including 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 [XMI24]

• MOF 2 Facility and Object Lifecycle - for connecting to and managing collections of MOF-based model elements [MOFFOL]

• MOF 2 Versioning and Development Lifeycle - 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]
