| Full name | News Industry Text Format |
| Description | An XML-based format, developed by the International Press Telecommunications Council. NITF represents the content and structure of news articles and accompanying metadata. The intent of NITF is as a base format, from which publishers can adapt the look, feel, and interactivity of their documents to the bandwidth, devices, and personalized needs of their subscribers. NITF documents can be translated into HTML, WML (for wireless devices), RTF (for printing), or any other format the publisher wishes. Version 3.2 of NITF was released in October 2003. This format description does not attempt to distinguish between versions, but covers NITF in general. |
