The Microsoft Operations Framework ( MOF ) is based on ITIL v2.
While ITIL deliberately aims to be platform-agnostic, MOF is designed by Microsoft to provide a common management framework for its products.
The Meta-Object Facility ( MOF ) is an Object Management Group ( OMG ) standard for model-driven engineering.
MOF is designed as a four-layered architecture.
This M3-model is the language used by MOF to build metamodels, called M2-models.
The most prominent example of a Layer 2 MOF model is the UML metamodel, the model that describes the UML itself.
A supporting standard of MOF is XMI, which defines an XML-based exchange format for models on the M3 -, M2 -, or M1-Layer.

MOF allows a strict meta-modeling architecture ; every model element on every layer is strictly in correspondence with a model element of the layer above.
MOF is an international standard:
Kermeta is an extension to MOF allowing executable actions to be attached to EMOF meta-models, hence making it possible to also model a DSL operational semantics and readily obtain an interpreter for it.
OMG's MOF is not to be confused with the Managed Object Format ( MOF ) defined by the Distributed Management Task Force ( DMTF ) in section 6 of the Common Information Model ( CIM ) Infrastructure Specification, version 2. 5. 0.
The MDA model is related to multiple standards, including the Unified Modeling Language ( UML ), the Meta-Object Facility ( MOF ), XML Metadata Interchange ( XMI ), Enterprise Distributed Object Computing ( EDOC ), the Software Process Engineering Metamodel ( SPEM ), and the Common Warehouse Metamodel ( CWM ).
One of the characteristics of MDA tools is that they mainly take models ( e. g. MOF models or metamodels ) as input and generate models as output.
The Object Constraint Language is a precise text language that provides constraint and object query expressions on any MOF model or meta-model that cannot otherwise be expressed by diagrammatic notation.
The MOF format is a specific syntax to define CIM class representation in an ASCII file ( e. g. MIB are to SNMP what MOF files are to CIM ).

MOF and Domain
MOF can be viewed as a standard to write metamodels, for example in order to model the abstract syntax of Domain Specific Languages.

MOF and Language
The Object Management Group ( OMG ) has developed a metamodeling architecture to define the Unified Modeling Language ( UML ), called the Meta-Object Facility ( MOF ).
MOF originated in the Unified Modeling Language ( UML ); the OMG was in need of a metamodeling architecture to define the UML.
* Meta-Object Facility ( MOF ), a different standard for the Unified Modeling Language ( UML ) of the Object Management Group ( OMG )
The MOF is a metamodel ( a model of any kind of metadata ) used notably to define the Unified Modeling Language ( or UML ).

MOF and used
It can be used for any metadata whose metamodel can be expressed in Meta-Object Facility ( MOF ).
MOF may be used to define object-oriented metamodels ( as UML for example ) as well as non object-oriented metamodels ( as a Petri net or a Web Service metamodel ).
OCL may now be used with any Meta-Object Facility ( MOF ) Object Management Group ( OMG ) meta-model, including UML.
The MOF / XMI specifications are used for the exchange of UML models.

MOF and define
MOF only provides a means to define the structure, or abstract syntax of a language or of data.
In short MOF uses the notion of MOF :: Classes ( not to be confused with UML :: Classes ), as known from object orientation, to define concepts ( model elements ) on a metalayer.

MOF and metamodels
* MOF – Meta Object Facility, an OMG language for specifying metamodels.
Beyond the M3-model, MOF describes the means to create and manipulate models and metamodels by defining CORBA interfaces that describe those operations.
Because of the similarities between the MOF M3-model and UML structure models, MOF metamodels are usually modeled as UML class diagrams.
For defining metamodels, MOF plays exactly the role that EBNF plays for defining programming language grammars.
This approach is based on the utilization of a language to write metamodels called the Meta Object Facility or MOF.
All the languages presented below could be defined as MOF metamodels.

MOF and EBNF
Similarly to EBNF, MOF could be defined in MOF.
Derived meta-metamodels include Entity Relationship Diagrams, Formal languages, EBNF, Ontology languages, XML Schema, and MOF.

MOF and for
