2. OMG OMF #
Object Management Group OMG + Meta Object Facility MOF.
This material is a very short summary of the official document from OMG : omg.org/ocup-2/documents/Meta-ModelingAndtheMOF.pdf
OMG - The Object Management Group® (OMG®) is an international, open membership, not-for-profit technology standards consortium, founded in 1989.
MOF - The Meta Object Facility provides an open and platform-independent metadata management framework and associated set of metadata services to enable the development and interoperability of model-and metadata-driven systems.
The MOF2.5 specification provides the basis for metamodel definition in OMG’s family of modeling languages (including the UML) and is based on a simplification of UML 2’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
Basically, OMF uses UML elements to build concepts used in UML.
An amazing thesis about MOF : Overbeek, J.F. (2006) Meta Object Facility (MOF): investigation of the state of the art.
