The International Press Telecommunications Council (IPTC) is an international consortium of the world's major news agencies, news publishers and news industry vendors. It develops and maintains technical standards for improved news exchange that are used by virtually every major news organization in the world. Among other activities, IPTC provides numerous classification schemas to standardize the coding of article metadata.

There are several models that implement this classification in several different languages. The classification is done in the categories defined by the edition released in December 2010 of IPTC's subject code taxonomy. This edition contains 1388 non-deprecated categories.
