IBM Document Composition Facility helps
you create mission-critical documents and respond to functional requirements
quickly with a robust range of formatting capabilities.
DCF provides a markup language that
facilitates the creation of documents made up of multiple elements, such as
headings, paragraphs, lists, tables and other document components. The use
of its Generalized Markup Language (GML) allows the document creator to effectively
separate document content from document format.
GML tags are used to identify different elements of the document to the
text formatter. When the document is formatted, the SCRIPT formatter matches
each tag to a set of instructions that tells how that element is to be formatted.
This set of instructions is sometimes called a style sheet. You can change
the appearance of an entire document simply by processing it using a different
style sheet. Style sheets can also provide a way to ensure formatting consistency
in documents that are created by multiple authors. Each author does not have
to know what fonts to use, or whether text paragraphs will be justified,
ragged, or placed in columns. Those decisions are made by a central administrator,
and implemented in the style sheets.
Since DCF is intended for use in creating
mission critical documents such as product specification or maintenance
manuals, policy and procedures documentation, or legal documents, it incorporates
a complete range of document formatting capabilities that are often not
found in desktop publishing programs. Some of these include:
- Output generation in either AFP or PostScript® formats
- Table of contents and index generation
- Running headings and footings, including security classifications
- Multi-column formatting
- Keeping text together, or floating text to the top of a page or column, and widow
- Revision codes with version control
- Hypertext linking for document usability with the AFP Viewer
- Indexing tags for easier document navigation
- Symbol and macro-instruction processing
- Conditional processing of tags and commands
- Complex table construction
- Mathematical formulas
- Multi-pass formatting for forward and backward references
- Inclusion of AFP overlays, or AFP or PostScript images as Encapsulated PostScript (EPS)
- Support for full process or highlight color
- Spelling verification and hyphenation in 15 languages
DCF is supported under IBM's industry-leading Software Support Family of Services,
giving you 24 x 7 coverage for your DCF applications. This IBM Printing Systems
Web site offers no charge tools to assist you with your DCF application development.
A new utility that is available on the Printing Systems Web site, B2H, allows
you to translate documents created using IBM GML, BookMaster or SCRIPT/VS,
or "flat" text files, into HTML so that they can be viewed on the
Web using a common Internet browser. Another utility, H2S, allows you to translate
a Web-based text document in HTML into a format that can be printed on a high-speed
AFP printer such as the IBM Infoprint® 4000.
Printing performance for documents created using DCF is dependent upon the
complexity of the document and any included resources, such as overlays and
images, and cannot be determined in advance. The customer must realize that
more complex documents will require more system resources and may take longer
to print than documents with simpler formatting.
