NAME

DDIS, ddis - Digital Data Interchange Syntax / ISO ASN.1 (DDIS/ASN.1) files  

DESCRIPTION

DDIS is an ASN.1 syntax that conforms to the specifications of International Standards Organization Abstract Syntax Notation One (ISO ASN.1).

Digital's CDA architecture defines two document formats and a mail syntax for the sharing and transport of revisable compound documents and tabular files based on the DDIS syntax that is a subset of ASN.1: DDIF (Digital Document Interchange Format) is the interchange and application file format for compound documents containing text, graphics, images, and audio. DTIF (Digital Table Interchange Format) is the interchange and application file format for tabular data, such as spreadsheets and multi-dimensional tables. DOTS (Data Object Transport Syntax) is a transparent interface for the transfer of compound documents with external links to multiple subfiles via mail systems.

CDA-supported files that conform to one of the DDIS/ASN.1 family of syntaxes are typed according to a particular DDIS/ASN.1 syntax. For example, a DDIF file is identified by the file command as a ddis/ddif file.

For more information on CDA enabling technologies and the DEC CDA Run-Time Services, refer to the CDA(4) manpage.
