Dr. Jon Siegel, OMG's Vice President, Technology Transfer, will present the tutorial "Introduction and Overview of OMG Specifications." OMG specifications support the enterprise at every level – A model built using one of our standards may represent an aspect as abstract as business motivation or as concrete as an entire system’s software, hardware and staff; models of software may be transformed into code or executed directly on systems as large as a continent-spanning telecoms network or as small as a single chip. Our middleware standards include the still-vital CORBA® (for both conventional and real-time systems) and the publish-subscribe Data Distribution Service (DDS™). In this tutorial, we’ll start our survey with business modeling standards including the Business Motivation Metamodel (BMM), Business Process Maturity Model (BPMM), and widely-used Business Process Model and Notation (BPMN™) V2. Then we’ll see how the Meta-Object Facility (MOF™) defines the metamodeling foundation that members have built upon to model software with the Unified Modeling Language (UML®), systems engineering with the Systems Modeling Language (SysML™), data with the Common Warehouse Metamodel (CWM™, soon to become the Information Management Metamodel or IMM™), and the entire software development and support lifecycle with the Model-Driven Architecture (MDA®). Finally we’ll examine how, taking advantage of this broad base, OMG members define model-based specifications enabling interoperability in a wide range of vertical domains including healthcare, finance, C4I, robotics, business process, government, manufacturing, space, and others.
