ISO/IEC TR 19758:2003 provides a DSSSL (ISO/IEC 10179:1996) library that makes it feasible to describe DSSSL specification for documents described by SGML (ISO 8879:1986) or XML (Extensible Markup Language).

The library can deal with some complex compositions programmed by a number of complicated DSSSL specification statements. Those compositions consist of the formatting objects: paper size, paper placement, unit, basic composition style, font, character size, headline, page number, note, inlinenote, emphasizing mark, superscript/subscript, word-length adjustment, character space adjustment, clause, list, table, heading, ruby, paragraph indentation, score, rule, and inline.

The DSSSL library contains the simple parameter data and the four files:

  • full parameter generator;
  • function set;
  • page model set;
  • flow object construction rules.

Their actual data are specified in ISO/IEC TR 19758:2003.

This standard defines the command set extensions to facilitate operation of SCSI direct-access block devices. The clauses of this standard, implemented in conjunction with the applicable clauses of SPC-3, fully specify the standard command set for SCSI direct-access block devices. The objective of this standard is to: a) permit an application client to communicate over a SCSI service delivery subsystem with a logical unit that declares itself to be a direct-access block device in the PERIPHERAL DEVICE TYPE field of the standard INQUIRY data (see SPC-3); and b) define commands unique to the direct-access block device type.

ISO/IEC 1001:2012 specifies the file structure and the labelling of magnetic tapes for the interchange of information between users of information processing systems. It specifies - volume and file structure, - basic characteristics of the blocks containing the records constituting the file, - recorded labels for identifying files, file sections and volumes of magnetic tapes, and - four nested levels of interchange.

ISO/IEC 13250-2:2006 specifies the Topic Maps data model. It defines the abstract structure and interpretation of topic maps, the rules for merging topic maps and a set of fundamental subject identifiers. The purpose of the data model is to define the interpretation of the Topic Maps interchange syntax, and to serve as a foundation for the definition of supporting standards for canonicalization, querying, constraints, etc.
