DDIS(5) File Formats Manual DDIS(5)
Name
DDIS - Digital Data Interchange Syntax / ISO ASN.1 (DDIS/ASN.1) files
Description
DDIS/ASN.1 files conform to Digital's Digital Data Interchange Syntax. DDIS conforms to syntaxes that can be defined within the specifica-
tions of International Standards Organization Abstract Syntax Notation One (ISO ASN.1), but is not itself an implementation of full ISO
ASN.1 syntax.
DDIS/ASN.1 files conform to the DDIS/ASN.1 syntax. The DDIS/ASN.1 syntax is itself used to define other syntaxes. The following are among
the syntaxes that are subsets of DDIS/ASN.1:
DDIF Digital Document Interchange Format
DTIF Digital Table Interchange Format
DOTS Data Object Transport Syntax
Files that conform to one of the DDIS/ASN.1 family of syntaxes are described as DDIS/ASN.1 files. More specifically, however, the files
are typed according to a particular DDIS/ASN.1 syntax. For example, a file that conforms to the DDIF syntax is a DDIF file, and is identi-
fied by the command as a ddis/ddif file. The command includes the string ddis/ as a part of its output if a file belongs in the DDIS fam-
ily.
