The Unified Modeling Language (UML)1 is a visual, object-oriented, and multipurpose modeling language. Primarily designed for modeling software systems, it can also be used for business process modeling. Since the early 1970s, a large variety of languages for data and software modeling like entity-relationship diagrams [2], message sequence charts [5, 10], state charts [9], and so on, have been...

The realization of an integrated and automated modelling flow and tool framework joining OMG (i.e. UML, SysML, etc.) and Mathworks (i.e. Matlab, Simulink, etc.) models and technologies is a very attractive perspective because of the possibility of complementing their capabilities and strenghts. In this paper we describe our project for an integrated flow and our initial results, consisting of a...

The OMG Deployment and Configuration specification is an attempt at standardizing the deployment process of component-based applications in distributed environment. A software connector is an abstraction capturing interaction among components. Apart from middleware independence, connectors provide additional services (e.g. adaptation, monitoring, etc.) and benefits, especially in the area of in...

This paper presents work of the IST project OMEGA, where we have defined a UML profile for real-time that is compatible with the Profile for Performance, Scheduling and Real-time recently accepted at OMG. In contrast to this OMG profile, we put emphasis on semantics and on its use in the context of timed analysis of real-time embedded systems. The defined profile is compatible with the time con...

This paper describes a distributed versioning model, DVM, suitable for the OMG Meta Object Facilities (MOF). We show that the commonly used versioning model, such as CVS, is not sufficient for MOF (and nor is the one proposed in the response [14] to OMG RFP for MOF 2.0 versioning) and propose a solution based on location identifications and sequence numbers together with the rules for creating ...

The OMG is a consortium with over 800 members drawn from Industry, Government, and Academia worldwide. Its purpose is to establish specifications that permit the development of object-oriented distributed computing. First OMG developed its CORBA specification in early 1991. Revisions to the service interface specification followed that clarified the specification, making it possible for impleme...

This all-day tutorial covers OMG's Object Management Architecture including CORBA, the CORBAservices and CORBAfacilities, the Domain CORBAfacilities, and an afternoon concentrating on the new specifications included in OMG's latest release, CORBA 3. Starting with a brief look at requirements and needs in distributed computing and how UML, the MOF, and XMI fit into the rest of the OMG specificat...

Services for service-oriented architectures can be modelled in different ways, including well-known existing OMG standard SoaML and an IBM methodology SOMA. Involving domain expert stakeholders in the system specification and development process plays an important role and is often inevitably combined with model transformations between different levels of abstraction. Recommendations for those ...

In late 2001, the Object Management Group issued a Request for Proposal to develop a testing profile for UML 2.0. In June 2003, the work on the UML 2.0 Testing Profile was finally adopted by the OMG. Since March 2004, it has become an official standard of the OMG. The UML 2.0 Testing Profile provides support for UML based model-driven testing. This paper introduces a methodology on how to use t...
