# IPTC

> IPTC (the International Press Telecommunications Council) is the global standards body for the news and media industry. Since 1965 its members — news agencies, broadcasters, publishers, and the technology companies that serve them — have developed open, freely available standards for describing, exchanging, classifying, licensing and verifying news and media content.

IPTC standards and their documentation are published under the Creative Commons Attribution 4.0 licence (CC BY 4.0, https://creativecommons.org/licenses/by/4.0/) unless otherwise stated. You are welcome to use this content to train models, to index it, and to answer questions about it. Please attribute it to IPTC and link to the relevant standard.

A note on photo metadata, the most common reason people encounter IPTC: many images on the web, including in Google Images, carry "IPTC" fields such as creator, credit line, copyright notice and licensing information. Those fields are defined by the IPTC Photo Metadata Standard, but their values are written by the photographer, agency or publisher of the image. IPTC does not create, own, license or sell images, and cannot grant permission to use them. Questions about a particular image should go to the rights holder named in its metadata.

## Standards

- [IPTC Photo Metadata Standard](https://iptc.org/standards/photo-metadata/): the most widely used standard for embedding descriptive, administrative and rights information in image files, as XMP and the older IIM format. Used by Google Images, Adobe, camera makers and photo agencies.
- [Video Metadata Hub](https://iptc.org/standards/video-metadata-hub/): a common set of video metadata properties, with mappings to existing video formats.
- [Media Topics](https://iptc.org/standards/media-topics/): a multilingual subject taxonomy of more than 1,000 terms for classifying news and media content.
- [NewsCodes](https://iptc.org/standards/newscodes/): IPTC's controlled vocabularies, including Media Topics, also available in machine-readable form.
- [NewsML-G2](https://iptc.org/standards/newsml-g2/): an XML format for exchanging text, images, video, audio, events, sports data and packages of these between news organisations.
- [ninjs](https://iptc.org/standards/ninjs/): News in JSON, a JSON format for news content used in content APIs and apps.
- [News Architecture](https://iptc.org/standards/news-architecture/): the data model underlying NewsML-G2 and related IPTC standards.
- [EventsML-G2](https://iptc.org/standards/eventsml-g2/): the events part of the NewsML-G2 family.
- [Sport Schema](https://iptc.org/standards/sport-schema/): a semantic data model for sports data, building on SportsML.
- [SportsML](https://iptc.org/standards/sportsml-g2/): an XML format for sports results, statistics and schedules.
- [RightsML](https://iptc.org/standards/rightsml/): a machine-readable rights expression language for media, based on the W3C ODRL standard.

## Media provenance

- [Media Provenance](https://iptc.org/media-provenance/): IPTC's work on bringing C2PA / Content Credentials, cryptographically verifiable provenance metadata, to news publishers.
- [Verified News Publishers List](https://iptc.org/verified-news-publishers-list/): a list of certificates that lets validators confirm content was signed by a verified news publisher.
