Revisable-Form Text
Revisable-Form Text is part of IBM's Document Content Architecture. It is sometimes referred to as Revisable Format Text. It was used by IBM DisplayWrite 4 and 5 word processors on System/360 and 370 mainframe computers, and OfficeVision/400 to allow transfer of formatted documents to other systems.
RFT has a counterpart Final-Form Text, which was not intended to be editable and was output-only.
