The Free On-line Dictionary of Computing (30 December 2018):
Object Management Group
(OMG) A consortium aimed at setting standards in
object-oriented programming. In 1989, this consortium,
which included IBM Corporation, Apple Computer Inc. and
Sun Microsystems Inc., mobilised to create a
cross-compatible distributed object standard. The goal was a
common binary object with methods and data that work using all
types of development environments on all types of platforms.
Using a committee of organisations, OMG set out to create the
first Common Object Request Broker Architecture (CORBA)
standard which appeared in 1991. As of February 1998, the
latest standard is CORBA 2.2.
