IPTC 7901 is a news service text markup specification published by theInternational 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 fixedmetadata fields and a series of control and other special characters, IPTC 7901 was designed to feed text stories to bothteleprinters 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.
Although superseded in the early 1990s byIPTC Information Interchange Model and later by the XML-basedNews Industry Text Format, 7901's huge existing user base has persisted.
IPTC 7901 is closely related toANPA-1312 (also known as ANPA 84-2 and later 89-3) of theNewspaper Association of America.
The standard replaces several of the ASCII control codes:[1][2]
| Seq | Dec | Hex | Replaced | Abbrev | Name | Description |
|---|---|---|---|---|---|---|
^I | 09 | 09 | HT | FO | Formatting | 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 theUS control as a column break in tables. |
^K | 11 | 0B | VT | ECD | End of Instruction | Delimits the end of a typographical instruction intended for the typesetting device. |
^L | 12 | 0C | FF | SCD | Start of Instruction | Delimits the start of a typographical instruction intended for the typesetting device. |
^M | 13 | 0D | CR | QL | Quad Left | Terminates a line, indicating that it should be left-aligned. The current IPTC specification instead recommends using regular ASCII C0 controls, and representing this function with the< CR LF sequence. |
^Q | 17 | 11 | DC1 | FT1 | Font One | Switches to regular typeface, i.e. disables bold or italic. |
^R | 18 | 12 | DC2 | FT2 | Font Two | Switches to italic typeface. |
^S | 19 | 13 | DC3 | FT3 | Font Three | Switches to bold typeface. |
^W | 23 | 17 | ETX | ? | End of paragraph | |
^X | 24 | 18 | CAN | KW | Kill Word | Deletes the preceding word (deletes back to and including the last space, or back to and excluding the previous line break, whichever it encounters first). Retains "Cancel" semantics in this respect, but has a more specific function. |
^Y | 25 | 19 | EM | EMSP | Em space | For indenting the first line of a paragraph |
^\ | 28 | 1C | FS | SS | Super Shift | Non-locking shift code. |
^\ | 28 | 1C | FS | ? | ? | "Central Field Separator" in tables |
^] | 29 | 1D | GS | QC | Quad Centre | Terminates a line, indicating that it should be centred. |
^] | 29 | 1D | GS | ? | ? | Mark following space asnon-breaking |
^^ | 30 | 1E | RS | QR | Quad Right | Terminates a line, indicating that it should be right-aligned. |
^^ | 30 | 1E | RS | ? | ? | Mark followinghyphen-minus as asoft hyphen |
^_ | 31 | 1F | US | JY | Justify | Terminates a line which is to be justified. |
