What is ISO/IEC TR 9573-13- Techniques for using SGML - Public entity sets for mathematics and science about?
Tens of thousands of graphic characters are used in the publishing of text, of which relatively few have been incorporated into standard coded character sets. Even where standard coded representations exist, however, there may be situations in which they cannot be keyboarded conveniently; or in which it is not possible to display the desired visual depiction of the characters.
To help overcome these barriers to successful interchange of SGML documents, ISO/IEC TR 9573-13 defines character entity sets for some of the widely used special graphic characters. The entity repertoires are based on applicable published and proposed International Standards for coded character sets, and current industry and professional society practice.
Entity repertoires are necessarily larger and more repetitious than character sets, as they deal in general with higher-level constructs. For example, unique entities have been defined for each accented Latin alphabetic character, while a character set might represent such characters as combinations of letters and diacritical mark characters. These public entity sets should therefore not be construed as requirements for new standard coded character sets.
In many instances upper- and lower-case is used to differentiate the names of different entities. It is thus assumed that a concrete syntax where entity names are case sensitive is used.
Who is ISO/IEC TR 9573-13- Techniques for using SGML - Public entity sets for mathematics and science for?
ISO/IEC TR 9573-13 on techniques for using SGML - Public entity sets for mathematics and science is useful for:
- The information technology industry
- SGML support facilities
- Graphic designers
- Data handling companies
- IT engineers/ relevant technical teams
Why should you use ISO/IEC TR 9573-13- Techniques for using SGML - Public entity sets for mathematics and science?
ISO/IEC TR 9573 includes a tutorial on the basic components of the SGML language. ISO/IEC TR 9573-13 includes notes on the analysis of a document prior to the writing of a formal document type definition, and a series of examples illustrating the use of SGML in various situations together with a discussion of the advantages and disadvantages of different approaches. One example given is for a general document type, others of a general nature are for letter and memorandum, and the mixing of text and graphics.
The special considerations that apply for use of SGML with non-Latin based languages, as well as linguistic applications, are discussed and examples are shown. Other parts of ISO/IEC TR 9573 contain sample applications of a specialized nature, such as for mathematics, chemistry, and tables. Public entity sets covering a wide variety of widely used special graphic characters are defined in ISO/IEC TR 9573-13.
Note: ISO/IEC TR 9573 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.
