- P1003.0/D13 GUIDE TO THE POSIX OPEN SYSTEMS
-
- formal standards (e.g., international or national standards) informal
- standards groups typically submit their specifications to formal
- standards organizations.
-
- The term ``de facto standard'' is sometimes applied to popular vendor-
- defined systems. Such systems, however, are closed systems, often
- controlled in a proprietary fashion. Although they have value, closed de
- facto standards are not the subject of this guide.
-
- Most standards bodies support three types of status for their standards
- or specifications--approved, draft, and work item. An approved standard
- is one that has been fully ratified by whatever means the approving
- standards body uses. A draft standard is one that has yet to be fully
- ratified, such as an ISO DIS (Draft International Standard) or a CEN ENV.
- Work item is a catch-all phrase for everything else, such as immature
- specifications, technical reports, etc., that have not yet achieved draft
- status.
-
-
- C.1.1 International Standards Bodies Overview
-
- Standards with the highest status are internationally agreed ones. In
- information technology, these are produced and published by the
- International Organization for Standardization (ISO). Other standards
- and/or recommendations are issued by the International Electrotechnical
- Commission (IEC), the International Telecommunication Union (ITU), and
- the CCITT. International standards bodies participants are normally
- countries and trade bodies, rather than individual suppliers or users.
-
-
- C.1.2 National Standards Bodies Overview
-
- Like the international standards bodies, most national bodies do not
- admit either suppliers or users directly, but receive representatives
- from interested trade bodies. In general, the national bodies support
- and adopt the international standards, developing national standards only
- if no international standards are available, or to meet special national
- requirements. Each country has a national body that is the formal
- representative to the international standards groups.
-
- The relationship between the major international and national standards
- groups is shown in Figure C-1.
