NEEDHAM, Mass.--(BUSINESS WIRE)--June 12, 2003

At last week's Object Management Group(TM) (OMG(TM)) Technical meeting in Paris, France, the Analysis and Design Task Force voted to recommend adoption of the Unified Modeling Language(TM) (UML(TM)) 2.0 Superstructure specification, completing the definition of this major upgrade to the industry's main software modeling notation. Complementary MetaObject Facility(TM) (MOF(TM)) 2.0 specifications for the MOF Core and XML Metadata Interchange(R) (XMI(R)) were also recommended, updating the repository foundation upon which UML and Model Driven Architecture(R) (MDA(R)) tools are built. Alignment of the UML 2.0 metamodel with the MOF metamodel will simplify model interchange via XMI, and cross-tool interoperability.

"Based on our 5+ years of experience in using UML, we have learned a great deal about unifying modeling languages. Using this knowledge, UML 2.0 literally represents the next evolutionary step in our ability to express and communicate system specifications -- one which provides a sound basis for MDA," said Jim Odell, noted consultant and writer as well as the co-chair of the Analysis and Design Task Force.

"With over 50 companies contributing their best technology and best practices to this release, the OMG process once again proves itself, turning out a major new standard that will have a resounding impact on the future of software development," remarked Dr. Richard Soley, OMG Chairman and CEO.

The upgraded UML standard now has the following features:

- A first-class extension mechanism allows modelers to add their

own metaclasses, making it easier to define new UML Profiles

and to extend modeling to new application areas.

- Built-in support for component-based development to ease

modeling of applications realized in Enterprise JavaBeans,

CORBA(R) components or COM+.

- Support for run-time architectures allows modeling of object and

data flow among different parts of a system. Support for

executable models improved in general.

- More accurate and precise representation of relationships

improves modeling of inheritance, composition and aggregation,

and state machines.

- Better behavioral modeling improves support for encapsulation

and scalability, removes restrictions on mapping of activity

graphs to state machines, and improves Sequence diagram

structure.

- Overall improvements to the language simplifies syntax and

semantics, and better organizes its overall structure.

About The OMG

With well-established standards covering software from design and development, through deployment and maintenance, and extending to evolution to future platforms, the Object Management Group (OMG) supports a full-lifecycle approach to enterprise integration which maximizes ROI, the key to successful IT. OMG's standards cover multiple operating systems, programming languages, middleware and networking infrastructures, and software development environments. OMG's Modeling standards, the basis for the MDA, include the Unified Modeling Language (UML) and Common Warehouse Metamodel (CWM). CORBA, the Common Object Request Broker Architecture, is OMG's standard open platform with hundreds of millions of deployments running today.

Headquartered in Needham, MA, USA, with a U.S. government representative in Washington, DC, and international marketing representatives in Japan, the UK, and Germany, the Object Management Group is an international, open membership, not-for-profit computer industry specifications consortium. OMG member companies write, adopt, and maintain the organization's standards following a mature, open process.
