Developed by the International Press Telecommunications Council (IPTC).
"NewsML is a compact, extensible and flexible structural framework for news, based on XML and other appropriate standards and specifications. It supports the representation of electronic news items, collections of such items, the relationships between them, and their associated metadata. It allows for the provision of multiple representations of the same information, and handles arbitrary mixtures of media types, formats, languages and encodings. It supports all stages of the news lifecycle and allows the evolution of news items over time. Though media-independent, NewsML provides specific mechanisms for handling text. It allows the provenance of both metadata and news content to be asserted." From NewsML Overview in Functional Specification from IPTC.
