The purpose of MIF is to represent FrameMaker documents in a relatively simple, ASCII-based format, which can be produced or understood by other software systems and also by humans. Any document that can be created interactively in FrameMaker can also be represented, exactly and completely, in MIF (the reverse, however, is not true: a few FrameMaker features are available only through MIF). All versions of FrameMaker can export documents in MIF, and can also read MIF documents, including documents created by an earlier version or by another program.
