Establishes a structure for the assignment of identifying data codes to locational entities in the United States and its outlying and associated areas, for the purpose of information interchange among data-processing systems. Types of locational entities for which this strucutre is intended include (but are not limited to) populated places, primary county divisions such as townships and New England towns, Indian reservations, and facilities such as airports and military bases. This standard also establishes requirements for associated data that improve the utility of the primary data codes.

Lays down rules for converting between 58 characteristics of CCITT International Telegraph Alphabet No. 2 (Recommendation F.1) and the characters according to the ISO 646 and 6937-2 coded sets. Serves for interaction between international telex service and terminals in data networks if telex character repertoire is sufficient.

This Technical Report complements ISO 8879 by providing additional tutorial information. It is not intended, and should not be regarded, as an extension, modification, or interpretation of ISO 8879. The SGML language contains a number of components, some of which are optional features. The tutorial information covers the main components of the language only; notably a discussion of LINK, CONCUR, and DATATAG is outside the scope of this Technical Report.

Defines the coding principles to be used in interchanging pictures consisting of graphic images in a 7-bit or 8-bit environment; the data structures to be used to represent the primitives describing a picture; the general datatypes which can be used as operands within a primitive. Does not deal with the presentation semantics of pictures. These are defined in the related International Standards. Applies to the data streams containing data structured in accordance with picture coding methods defined in ISO 9281.

The purpose of this Technical Report is to provide a general framework for discussing characters and glyphs. The framework is applicable to a variety of coded character sets and glyph-identification schemes. For illustration, this Technical Report uses ex-amples from characters coded in ISO/IEC 10646 and glyphs registered according to ISO/IEC 10036.This Technical Report?differentiates between coded characters and registered glyphs ?identifies the domain of use of coded characters and glyph identifiers ?provides a conceptual framework for the formatting and presentation of coded character data using glyph identifiers and glyph representationsThis Technical Report describes idealized principles that were not completely followed in coding characters for ISO/IEC 10646 and in registering glyphs according to ISO/IEC 10036. The fact that ISO/IEC 10646, ISO/IEC 10036, and other standards do not completely follow the principles in the model does not invalidate the model and does not diminish the utility of having the model.
