OMG Adds Fault Tolerance For CORBA Applications Extends CORBA Support Into Vertical Industries.Business/Technology Editors NEEDHAM, Mass.--(BUSINESS WIRE)--Jan. 27, 2000 The Object Management Group (OMG (1) See Object Management Group. (2) "Oh my God!" See digispeak. OMG - Object Management Group ) recently concluded its Technical Meeting week in Mesa, AZ, USA, sponsored by Computer Associates International. The highlight of this meeting was the adoption of specification standardizing fault tolerance, fail-over and recovery within CORBA-based applications. In addition, the OMG issued a Request for Proposal for Surveillance Interfaces for Air Traffic Control systems, and evaluated 23 responses to a UML (Unified Modeling Language) An object-oriented analysis and design language from the Object Management Group (OMG). Many design methodologies for describing object-oriented systems were developed in the late 1980s. Request for Information which will lead to a major 2.0 release of the specification next year. The 5-day, OMG meeting attracted over 400 member representatives and their guests who met to work on approximately 90 technology adoptions in process. Current OMG work in process will extend existing Object Management Architecture specifications including the Common Object Request Broker Architecture (standard, programming) Common Object Request Broker Architecture - (CORBA) An Object Management Group specification which provides a standard messaging interface between distributed objects. The original CORBA specification (1. (CORBA (Common Object Request Broker Architecture) A software-based interface from the Object Management Group (OMG) that allows software modules (objects) to communicate with each other no matter where they are located on a private network or the global ) and the Unified Modeling Language See UML. (language) Unified Modeling Language - (UML) A non-proprietary, third generation modelling language. The Unified Modeling Language is an open method used to specify, visualise, construct and document the artifacts of an object-oriented software-intensive system (UML) and generate industry specific interfaces and extensions effecting a wide range of industries from life sciences, manufacturing, and utilities, to transportation, finance and health care. Platform Technology Committee (PTC (PTC, Needham, MA, www.ptc.com) Long a world leader in mechanical computer-aided design, manufacturing and engineering software, PTC, through acquisitions and reorganization, has transformed itself into a leading provider of Internet-based B2B solutions for discrete manufacturers. ) Actions The Platform Technology Committee (PTC), responsible for the OMG's CORBA infrastructure, voted to adopt a specification for a Fault Tolerant CORBA architecture (orbos/2000-01-19 &orbos/2000-01-23) that standardizes control over fault management, including the management of replicas and automatic switching of services from failing components to replicated components. Fault tolerant functionality is an essential part of the computing infrastructure in industries that rely on applications to be available &uot;24 x 7&uot; (24 hours a day, seven days a week) without interruption regardless of power failures, system crashes, and other types of incidents. Examples include utilities applications for power plant service management, financial stock trading applications, news and media delivery such as video and on-line news dissemination, and government national security applications. The PTC also adopted a Portable Interceptors specification (orbos/1999-12-02, orbos/1999-12-03, orbos/1999-12-14, &orbos/2000-01-01). Specialized services, such as security, intercept CORBA invocations in order to apply access conditions; development tools including debuggers and monitors also use interceptors to add their functionality to an ORB execution environment.By standardizing the functionality and interfaces of interceptors, OMG members enable development of ORB-independent add-on tools from third-party vendors. One more new service, enhancing and refining the representation of time in CORBA systems, was also adopted. All of these specifications will become official OMG technologies pending approval by the PTC in these votes and final approval by the Board of Directors in March 2000. Finally, the PTC issued a Request for Proposal initiating the adoption process for one new technology, XML Metadata Interchange The XML Metadata Interchange (XMI) is an OMG standard for exchanging metadata information via Extensible Markup Language (XML). It can be used for any metadata whose metamodel can be expressed in Meta-Object Facility (MOF). (XMI (1) (XML Metadata Interchange) An XML-based representation of a UML model. XMI is used to transfer UML diagrams between various modeling tools. See UML. (2) An earlier high-speed bus from Digital that was used in large VAX machines. ) production of XML Schemas (ad/2000-01-04). This RFP (Request For Proposal) A document that invites a vendor to submit a bid for hardware, software and/or services. It may provide a general or very detailed specification of the system. 1. (business) RFP - Request for Proposal. 2. will extend the XMI specification to allow users to continue to use XML XML in full Extensible Markup Language. Markup language developed to be a simplified and more structural version of SGML. It incorporates features of HTML (e.g., hypertext linking), but is designed to overcome some of HTML's limitations. DTDs as well as emerging XML schemas from the W3C. The end result will be additional interfaces to aid developers integrating metadata with distributed computing and development environments, the Internet, data warehousing and knowledge management applications. Domain Technology Committee Actions The Domain Technology Committee (DTC DTC See: Depository Transfer Check DTC See: Depository Trust Company DTC See Depository Trust Company (DTC). ) develops specifications for technologies specific to vertical markets. At this meeting, the DTC started a final vote on a new specification for Management of Event Domains (telecom/2000-01-01, telecom/2000-01-02, telecom/2000-01-03, &ab/2000-01-05) from the Telecom Domain Task Force. In addition, the DTC issued a Request for Information (RFI) to guide future standards work in the area of Traffic Center Management for intelligent highway systems in the transportation industry (transprt/2000-01-01), and issued four Requests for Proposals initiating work on new specifications: a Surveillance RFP in the area of Air Traffic Control (transprt/2000-01-09), a Workflow Resource Assignment Interfaces RFP (bom/2000-01-03), and an Electronic Commerce Registration and Discovery Service (ec/2000-01-05). Finally, the DTC issued an RFP to define Revision 2.0 of the Product Data Management Enablers specification (mfg/2000-01-02).

About The OMG With the support of its membership of software vendors, software developers and end users, the OMG's CORBA is &uot;The Middleware That's Everywhere(TM)&uot;. Since 1989, the OMG has been &uot;Setting The Standards For Distributed Computing(TM)&uot; through its mission to promote the theory and practice of object technology for the development of distributed computing systems. The goal is to provide a common architectural framework for object oriented applications based on widely available interface specifications. The OMG is headquartered in Needham, MA, USA and has international marketing offices around the world, along with US-based industry-specific representatives.
