UML is extensible, with two mechanisms for customization: profiles and stereotypes.

* Easy adaptation and extension of Objecteering using MDA technology ( UML profiles, Java API and transformation wizards, model transformation, MDA components, …)

UML profiles use stereotypes, stereotype attributes ( known as tagged values before UML 2. 0 ), and constraints to restrict and extend the scope of UML to a particular domain.

Examples of ideograms include wayfinding signs, such as in airports and other environments where many people may not be familiar with the language of the place they are in, as well as Arabic numerals and formal languages ( mathematical notation, logic, UML ), which are used worldwide regardless of how they are pronounced in different languages.

UML models may be automatically transformed to other representations ( e. g. Java ) by means of QVT-like transformation languages.

In general, every UML element may appear on almost all types of diagrams ; this flexibility has been partially restricted in UML 2. 0.

This problem is particularly pronounced if the implementation language does not adhere to orthodox object-oriented doctrine, since the intersection set between UML and implementation language may be that much smaller.

UML may refer to:

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 ).

The UML sequence diagram of interaction between these groups may look like:

Future work in adding support for x86 virtualization to UML may reduce this disadvantage.

For example an analyst may create a UML initial model from its observation of some loose business situation while a Java model may be automatically derived from this UML model by a Model transformation operation.

Among the various conferences on this topic we may mention ECMDA, the European Conference on MDA and also MoDELS, former firmed as << UML >> conference series ( till 2004 ), the Italian Forum on MDA in collaboration with the OMG.

OCL may now be used with any Meta-Object Facility ( MOF ) Object Management Group ( OMG ) meta-model, including UML.

The icon image may even replace the entire UML symbol.

The metamodels expressed in UML-XMI1. 2 may be uploaded in Poseidon for UML, a UML CASE tool.

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.

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.

* Meta-Object Facility, a meta-model used to formally define Unified Modeling Language ( UML )

CIM uses a model based upon UML to define the CIM Schema.

The MOF is a metamodel ( a model of any kind of metadata ) used notably to define the Unified Modeling Language ( or UML ).

While UML 2. 1 uses the « become » stereotype within the specification, it does not define it.

The UML specification explicitly states that associations in class models are extensional and this is in fact self-evident by considering the extensive array of additional " adornments " provided by the specification over and above those provided by any of the prior candidate " semantic modelling languages ".

UML provides mechanisms to represent class members, such as attributes and methods, and additional information about them.

A UML diagram or a semantic network has structured elements modelling relationships, with lines connecting objects to indicate relationship.

UML does not restrict UML element types to a certain diagram type.

In keeping with the tradition of engineering drawings, a comment or note explaining usage, constraint, or intent is allowed in a UML diagram.

It is also claimed that it is valid to use a UML diagram to express a Semantic Web graph.

A good mechanism should not be geared to a specific problem such as ensuring the consistency of a UML class diagram with the source code.

UML 2. 0, the current version, supports thirteen different diagram techniques, and has widespread tool support.
