CDA - Compound Document Architecture
Description
Digital's CDA architecture for compound documents is an open architecture that establishes a framework for the interchange of many types of
data in a multivendor environment. Utilizing CDA converters, compound revisable format data can be handled much the same as ASCII text.
With CDA converters, you can write applications that handle compound documents, regardless of the environment in which you or application
users are working.
CDA includes the Digital Document Interchange Format (DDIF), the Data Object Transport Syntax (DOTS), and the Digital Table Interchange
Format (DTIF). Each of these formats is encoded using the Digital Data Interchange Syntax (DDIS). Using these representations, CDA pro-
vides a method for manipulating files that contain a number of integrated components.
The tools associated with CDA include the CDA Toolkit (libddif.a), the CDA Converter (the main converter is and the CDA Viewers. The CDA
Toolkit is a collection of routines that support the creation of CDA applications. The CDA Converter converts files of a specified input
format to a specified output format. The CDA Viewers are used to display CDA-encoded files on a workstation display or character cell ter-
minal.
All of the following products support CDA-encoded files. If you only intend to manipulate CDA files, and do not have an interest in the
particulars of the file format, you can use any one of these products to manipulate a CDA-encoded file:
CDA Converters
CDA Viewers (dxvdoc, vdoc)
dxcardfiler
dxmail
dxpaint
PrintScreen

DOTS - Data Object Transport Syntax (DOTS) files
Description
Data Object Transport Syntax (DOTS) is DDIS/ASN.1 encoding for encapsulating the encoded interchange form of a number of related data
objects. Data objects must be related by having embedded references to other objects in the same DOTS encapsulation. Typically, these
embedded references depend on the storage address (for example, filename) of the referenced object. Therefore, when the referenced object
is moved from one location to another, the storage address must be updated.
The purpose of DOTS is to allow composite data objects to be moved from one location to another as a single object and to allow the neces-
sary storage reference to be updated as part of the process.
The primary use for DOTS is moving multifile compound documents in which one DDIF or DTIF file may have reference data stored in a physi-
cally separate file. Mail is a major vehicle for moving DOTS objects.
The commands and are used to pack and unpack DDIF and DTIF files. The commands can also be used to copy a related set of DDIF or DTIF
files, or both, from one location to another.

Hi All,
I am trying to set up a modem (using SLIP) on a Digital (well it used to be) AlphaStation running Digital Unix V7E. I assume that I have to put an entry into /remote but can anyone suggest the contents and formatting. Apologies for being so naive but I'm an ex VMS person.
Thanks and... (1 Reply)
