The Architecture Neutral Distribution Format (ANDF) in computing is a technology allowing common "shrink wrapped" binary application programs to be distributed for use on conformant Unix systems, translated to run on different underlying hardware platforms.
[2] Fifteen proposals were received, based on a variety of technical approaches, including obscured source code, compiler intermediate languages, and annotated executable code.
The technology of ANDF, chosen after an evaluation of competing approaches and implementations, was Ten15 Distribution Format, later renamed TenDRA Distribution Format, developed by the UK Defence Research Agency.
Various reasons have been proposed for this: for example, that having multiple installation systems would complicate software support.
[4] After OSF stopped working on ANDF, development continued at other organizations.
