Advanced Function Presentation

AFP
MO:DCA is implemented as IBM's Advanced Function Presentation (AFP) page description language.
MO:DCA-P (Mixed Object:Document Content Architecture-Presentation), the Page Description Language file format that describes the text and graphics on a page. The 'Mixed Object' moniker refers to the fact that a MO:DCA file can contain multiple types of objects, including text, images, vector graphics, and even objects marked as 'barcodes'. An application can simply include a string of digits along with controls that identify a specific type of barcode, and the rendering of bars will be done on the output platform (physical printer hardware or software emulation). A MO:DCA file consists of a sequential, ordered hierarchy of independent objects - documents, pages, data objects, and resource objects such as fonts and ICC profiles. Each object is delimited by begin/end structures, and objects to be rendered specify presentation parameters and resource requirements in structures called "environment groups". Since the pages in MO:DCA documents appear in sequential order, presentation can start as soon as the first page is received. The MO:DCA format is comparable to other PDLs that specify distinct pages such as PDF. MO:DCA-P is sometimes called AFPDS (AFP Data Stream).

Document Content Architecture

DCA was later extended as MO:DCA (Mixed Object Document Content Architecture), which added embedded data files, like graphics.

Revisable-Form Text

Revisable Form Text
MO:DCA supports Revisable Documents, which are editable like revisable-form text, Presentation Documents, which provide specific output formatting similar to final-form text, and Resource Documents, which hold control information such as fonts.
