In answer to your general question about the OMG, here's a brief overview. Feel free to call, fax or email for more information.
-- Richard Soley Vice President & Technical Director Object Management Group, Inc. and coincidentally, MIT '82, SM '85, PhD '89 (EECS)
The Object Management Group (OMG) is an international software industry consortium with two primary aims:
(*) promotion of the object-oriented approach to software engineering in general, and
(*) development of command models and a common interface for the development and use of large-scale distributed applications (open distributed processing) using object-oriented methodology.
In late 1990 the OMG published its Object Management Architecture (OMA) Guide document. This document outlines a single terminology for object-oriented languages, systems, databases and application frameworks; an abstract framework for object-oriented systems; a set of both technical and architectural goals; and an architecture (reference model) for distributed applications using object-oriented techniques. To fill out this reference model, four areas of standardization have been identified:
1) the Object Request Broker, or key communications element, for handling distribution of messages between application objects in a highly interoperable manner;
2) the Object Model, or single design-portability abstract model for communicating with OMG-conforming object-oriented systems;
3) the Object Services, which will provide the main functions for realising basic object functionality using the Object Request Broker - the logical modeling and physical storage of objects; and
4) the Common Facilities will comprise facilities which are useful in many application domains and which will be made available through OMA compliant class interfaces.
The OMG adoption cycle includes Requests for Information and Proposals, requesting detailed technical and commercial availability information from OMG members about existing products to fill particular parts of the reference model architecture. After passage by Technical and Business committees to review these responses, the OMG Board of Directors makes a final determination for technology adoption. Adopted specifications are available on a fee-free basis to members and non-members alike.
In late 1991 OMG adopted its first interface technology, for the Object Request Broker portion of the reference model. This technology, adopted from a joint proposal (named "CORBA") of Hewlett-Packard, NCR Corp., HyperDesk Corp., Digital Equipment Corp., Sun Microsystems and Object Design Inc. includes both static and dynamic interfaces to an inter- application request handling software "bus."
Unlike other organizations, the OMG itself does not and will not develop nor sell software of any kind. Instead, it selects and promulgates software interfaces; products which offer these interfaces continue to be developed and offered by commercial companies.
In order to serve OMG membership interested in other object-oriented systems arenas besides the distributed system problem, the Group supports Special Interest Groups for discussion of possible standards in other areas. These groups at present are:
1) Object Oriented Databases; 2) OO Languages; 3) End-User Requirements; 4) Parallel Processing; 5) Analysis & Design Methodologies; 6) Smalltalk; and 7) Class Libraries.
Any company, university/research institution or individual, whether end-user or vendor, can become a member of this body. Administrative details are given at the end of this paper.
