IPTC 7901 is a news service text markup specification published by the International Press Telecommunications Council that was designed to standardize the content and structure of text news articles. It was formally approved in 1979, and is still the world's most common way of transmitting news articles to newspapers, web sites and broadcasters from news services.
Using fixed metadata fields and a series of control and other special characters, IPTC 7901 was designed to feed text stories to both teleprinters and computer-based news editing systems. Stories can be assigned to broad categories (such as sports or culture) and be given a higher or lower priority based upon importance.
Used in tabular data to move to the next tabulation position (retaining "Tab" semantics in this regard), and in standard formats to denote the next phase. The current IPTC specification instead recommends using regular ASCII C0 controls, and using the US control as a column break in tables.
