- interchange file format — (file format) (IFF, full name "EA IFF 1985") A generic file format published by Electronic Arts as an open standard. IFF is chunk-based and hierarchical so files can include other files. It is easily extensible and an all round Good Idea. An IFF file starts with one of the following "group IDs": 'FORM', 'LIST' or 'CAT '. This is followed by an unsigned 32-bit number of bytes in the remainder of the file. Then comes an ID that indicates which type of IFF file this is. The main image type is ILBM, audio is either AIFF or 8SVX, animations are ANIM etc. An IFF file will probably have a filename extension related to this file type stored in the file. The rest of the file is divided into chunks each of which also has a four-byte header and byte count.

- object management group — (body) (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.
