FrameMaker is a document processor application, originally produced by Frame Technology Corp. but later bought by Adobe and released as Adobe FrameMaker. It is used primarily for creating technical documentation; it is of the genere of "document processors", similar to word processors and desktop publishers but specifically designed to create and maintain structured documents.
A FrameMaker 4.0 book consists of a .BK file along with one or more .TOC (table of contents) and .DOC (document) files. Later versions (e.g. 6.0 and 7.0) use the .BOOK extension.
Definitions of elements within a FrameMaker document are found in the Element Definition Document (EDD), normally embedded in the template.
For FrameMaker's MIF format, see Maker Interchange Format.
Software and Program Code
30-day trial versions of FrameMaker 7.0 are available which can open files back to at least version 4.0:
The documents can then be converted to various formats (Word 6.0, HTML, etc.), but the most faithful reproduction of the original formatting can be achieved by printing to a PDF printer (FoxIt has a free one for Windows).
