CDA Reference Manual

This manual serves as a reference for the CDA (Compound Document Architecture) Toolkit, designed to assist system and application programmers in creating compound document applications, converters, and viewer widgets. It provides detailed information on using DDIF (DIGITAL Document Interchange Format) and DTIF (DIGITAL Table Interchange Format) aggregates.

The CDA Toolkit, supported on both VMS and ULTRIX operating systems, offers a collection of data structures and routines for managing CDA documents. Key functionalities include:

• Document Processing: Details CDA item data types, default values, and processing options for DDIF, DTIF, CFE, and ESF aggregates.
• Converters: Describes the architecture for converting files between various input and output formats (DDIF, DTIF, Text, PostScript), including data mapping, conversion restrictions, and syntax error handling.
• Document Transfer: Explains procedures for mailing and copying CDA documents between VMS and ULTRIX systems.
• Toolkit Routines: Provides an alphabetical listing of routines for tasks such as creating, deleting, copying, converting, and manipulating document aggregates and items.
• Viewer Routines: Describes routines for developing character-cell or DECwindows viewer applications.
• Structures and Syntax: Offers in-depth descriptions and syntax diagrams for DDIF, DTIF, CFE, and ESF aggregate structures.

The manual also includes an example program, a text front end source file, details on VMS support for CDA in DECwindows, and a glossary of associated terminology.
