Information technology — Abstract Syntax Notation One (ASN.1): Information object specification — Part 2:

ISO/IEC 8824-2:2002 provides the ASN.1 notation which allows information object classes as well as individual information objects and sets thereof to be defined and given reference names. An information object class defines the form of a conceptual table (an information object set) with one column for each field in the information object class, and with each complete row defining an information object.
