The text transmission format
The IPTC has formulated its Recommendation 7901 for use in the transmission of text messages to newspapers, news agencies and other recipients. The first version appeared in the early eighties and was updated regularly, the last revision - number 5 - was approved in 1995. Since then the development of IPTC 7901 is frozen despite the fact that it is still used heavily in many countries.
Although designed primarily for computerized information handling, the Recommendation 7901 is also suitable for transmission to non-computerized recipients. The Recommendation has been influenced by the "Highspeed Wire Service Transmission Guidelines" contained in Bulletins 1312 and subsequent amendments thereto of the Newspaper Association of America (NAA), formerly the American Newspaper Publishers Association (ANPA).
Because it is intended for international use it takes into account technical and linguistic differences between countries and is designed for use in numerous languages and alphabets. To provide a degree of flexibility and to minimize changes from earlier practices, some elements in the Recommendation have been designed as "optional" or "recommended". Those not so designated must be complied with when using the Recommendation.
The Recommendation is code transparent. It was originally designed for use in conjunction with versions of the 7-bit coded character set of ISO 646 (CCITT Alphabet Nr. 5), later the possibility for use of alternate character sets (7 and 8 bit), including non-Latin alphabets, has been added (see 7. and Annex C).
