The International Press Telecommunications Council, in conjunction with Project Origin, has established a working group to create and manage a C2PA compatible list of verified news publishers.

The open C2PA 2.0 Content Credentials standard for media provenance is widely supported as a strong defence against misinformation. Recent announcements by OpenAI, Meta, Google and others have confirmed the value of an interoperable, tamper-evident way of confirming the source and technical integrity of digital media content.

Project Origin, as a co-founder of the C2PA, has brought the needs of the news publishing community to the forefront of the creation of this standard. This now includes the creation of a C2PA 2.0 compatible Origin Verified Publisher Certificate to be used by publishers to securely create a cryptographic seal on their content. The signing certificates will be available through the IPTC, who will work with C2PA validators to gain widespread acceptance. These signing certificates will be issued by the IPTC to broadcast, print and digital native media publishers.

Origin Verified Publisher Certificates will ensure that the identity of established news organisations are protected from imposters. The certificates confirm organisational identity and do not make any judgement on editorial position. Liaison agreements with other groups in the media ecosystem will be used to accelerate the distribution of certificates.

The initial implementation uses TruePic as a certificate authority, with the BBC and CBC/Radio-Canada as trial participants.

“As a founding partner of Project Origin, CBC/Radio-Canada is proud to be one of the first media organisations to trial Origin Verified Publisher Certificates,” said Claude Galipeau, Executive Vice-President, Corporate Development, CBC/Radio-Canada. “This initiative will provide our audiences with a new and easy way of confirming that the content they’re consuming is legitimately from Canada’s national public broadcaster. It’s an important step in our adoption of the Content Credentials standard and in our fight against misinformation and disinformation.”

Jatin Aythora, Director of BBC R&D, and vice chair for Partnership on AI, said “Media provenance increases trust and transparency in news, and so is an essential tool in the fight against disinformation. That fight has never been more important, and so we hope many more media organisations will join us in securing their own Origin Verified Publisher Certificate.”

Publishers interested in working cooperatively to advance the implementation of the C2PA standard in the news ecosystem are invited to join the Media Provenance Committee of the IPTC.

Sports-related NewsCodes updates

We also made some changes to our sports NewsCodes vocabularies, which are mostly used by SportsML and IPTC Sport Schema.

New vocabulary: Horse Position

New entries in Tournament Phase vocabulary: Heat, Round of 16

New entry in Soccer Position: manager,

News-related NewsCodes updates

Content Production Party Role: new term Generative AI Prompt Writer which can also be used in Photo Metadata Contributor to declare who wrote the prompt that was used to generate an image.

Genre: new term User-Generated Content.

Why Present: new term associated.

The User Action Type vocabulary, mostly used by NewsML-G2, has had some major changes.

Previously this vocabulary defined terms related to specific social media services or interactions. We have retired/deprecated all site-specific terms (Facebook Likes, Google’s +1,  Twitter re-tweets, Twitter tweets).

Instead, we have defined some generic terms: Like, Share, Comment. The pageviews term has been broadened into simply views (although the ID remains as “pageviews” for backwards-compatibility)

Thanks to the NewsCodes Working Group for their work on this release, and to all members and non-members who have suggested changes.

The IPTC News Architecture Working Group is happy to announce that the NewsML-G2 Guidelines and NewsML-G2 Specification documents have been updated to align with version 2.33 of NewsML-G2, which was approved in October 2023.

The IPTC is happy to announce the latest version of our guidance for mapping between photo metadata standards.

Following our publication of IPTC’s rules for mapping photo metadata between IPTC, Exif and schema.org standards in 2022, the IPTC Photo Metadata Working Group has been monitoring updates in the photo metadata world.

In particular, the IPTC gave support and advice to CIPA while it was working on Exif 3.0 and we have updated our mapping rules to work with the latest changes to Exif expressed in Exif 3.0.

As well as guidelines for individual properties between IPTC Photo Metadata Standard (in both the older IIM form and the newer XMP embedding format), Exif and schema.org, we have included some notes on particular considerations for mapping contributor, copyright notice, dates and IDs.

The IPTC encourages all developers who previously consulted the out-of-date Metadata Working Group guidelines (which haven’t been updated since 2008 and are no longer published) to use this guide instead.

We at IPTC receive many requests for help and advice regarding editing embedded photo and video metadata, and this has only increased with the recent news about the IPTC Digital Source Type property being used to identify content created by a generative AI engine.

In response, we have created some guidance: Developers’ and power users’ guide to reading and writing IPTC Photo Metadata 

This takes the form of a wiki, so that it can be easily maintained and extended with more information and examples.

In its initial form, the documentation focuses on:

• Using the ExifTool command-line tool to read and write IPTC Photo Metadata,. ExifTool is commonly used by developers and power users to explore embedded metadata;
• Reading and writing image metadata in Python using the pyexiftool module;
• Reading and writing metadata in JavaScript (or TypeScript) using the node-exiftool module.

In each guide, we advise on how to read and create DigitalSourceType metadata for generative AI images, and also how to read and write the Creator, Credit Line, Web Statement of Rights and Licensor information that is currently used by Google image search to expose copyright information alongside search results.

We hope that these guides will help to demystify image metadata and encourage more developers to include more metadata in their image editing and publishing workflows.

We will add more guidance over the coming months in more programming languages, libraries and frameworks. Of particular interest are guides to reading and writing IPTC Photo Metadata in PHP, C and Rust.

Contributions and feedback are welcome. Please contact us if you are interested in contributing.

The IPTC is proud to announce that after intense work by most of its Working Groups, we have published version 1.0 of our guidelines document: Expressing Trust and Credibility Information in IPTC Standards.

The culmination of a large amount of work over the past several years across many of IPTC’s Working Groups, the document represents a guide for news providers as to how to express signals of trust known as “Trust Indicators” into their content.

Trust Indicators are ways that news organisations can signal to their readers and viewers that they should be considered as trustworthy publishers of news content. For example, one Trust Indicator is a news outlet’s corrections policy. If the news outlet provides (and follows) a clear guideline regarding when and how it updates its news content.

The IPTC guideline does not define these trust indicators: they were taken from existing work by other groups, mainly the Journalism Trust Initiative (an initiative from Reporters Sans Frontières / Reporters Without Borders) and The Trust Project (a non-profit founded by Sally Lehrman of UC Santa Cruz).

The first part of the guideline document shows how trust indicators created by these standards can be embedded into IPTC-formatted news content, using IPTC’s NewsML-G2 and ninjs standards which are both widely used for storing and distributing news content.

The second part of the IPTC guidelines document describes how cryptographically verifiable metadata can be added to media content. This metadata may express trust indicators but also more traditional metadata such as copyright, licensing, description and accessibility information. This can be achieved using the C2PA specification, which implements the requirements of the news industry via Project Origin and of the wider creative industry via the Content Authenticity Initiative. The IPTC guidelines show how both IPTC Photo Metadata and IPTC Video Metadata Hub metadata can be included in a cryptographically signed “assertion” 

We expect these guidelines to evolve as trust and credibility standards and specifications change, particularly in light of recent developments in signalling content created by generative AI engines. We welcome feedback and will be happy to make changes and clarifications based on recommendations.

The IPTC sends its thanks to all IPTC Working Groups that were involved in creating the guidelines, and to all organisations who created the trust indicators and the frameworks upon which this work is based.

Feedback can be shared using the IPTC Contact Us form.

The IPTC NewsCodes Working Group has approved an addition to the Digital Source Type NewsCodes vocabulary.

The new term, “Composite with Trained Algorithmic Media“, is intended to handle situations where the “synthetic composite” term is not specific enough, for example a composite that is specifically made using an AI engine’s “inpainting” or “outpainting” operations.

The full Digital Source Type vocabulary can be accessed from https://cv.iptc.org/newscodes/digitalsourcetype. It can be downloaded in NewsML-G2 (XML), SKOS (RDF/XML, Turtle or JSON-LD) to be integrated into content management and digital asset management systems.

The new term can be used immediately with any tool or standard that supports IPTC’s Digital Source Type vocabulary, including the C2PA specification, the IPTC Photo Metadata Standard and IPTC Video Metadata Hub.

Information on the new term will soon be added to IPTC’s Guidance on using Digital Source Type in the IPTC Photo Metadata User Guide.

NEW YORK, NY, 26 JULY 2023: The IPTC today announced the beginning of a public feedback and review period of IPTC Sport Schema, which aims to be “the standard for the next generation of sports data.”

The announcement was made by Paul Kelly, Lead of the IPTC Sports Content Working Group, at the Sports Video Group’s Content Management Forum held at 230 Fifth Penthouse, New York.

“The SVG Content Management Forum is attended by senior tech experts from sports broadcasters and sports leagues from the US and around the world, so it is the perfect place to launch the IPTC Sport Schema,” said Kelly. “Many members of SVG have advised us on our work so far, including organisations such as Warner Bros Discovery, NBC Universal, PGA TOUR, Major League Baseball and Riot Games. Presenting our work at their event is a great way to say thanks for their help.”

While not yet an official IPTC standard, the IPTC Sports Content Working Group feels that the schema describing IPTC Sport Schema is solid enough to be published for public feedback.

Sports data for the era of linked data and knowledge graphs

The purpose of the IPTC Sport Schema project is to create a new RDF-based sports data standard, while making the most of the experience the IPTC has gained from the last 20 years of maintaining SportsML, the open XML-based sports data standard used by news and sports organisations around the world.

While XML served the industry well for many years, more recently developers and IPTC members have asked the Sports Content Working Group whether a standard would become available in a more modern serialisation format such as JSON, and whether knowledge graph protocols would be supported.

Because it is based on the W3C-standard RDF and OWL specifications, IPTC Sport Schema leverages the wide range of tools and expertise in the world of knowledge graphs, semantic web and linked open data, including the SPARQL query language, the JSON-LD serialisation into JSON format, inference using RDF Schema and OWL, and more.

“Using IPTC Sport Schema, sports leagues can choose to own their data,” said IPTC Managing Director Brendan Quinn. “Content publishers or sports leagues can publish open data on their website if they choose, in a way that can be re-mixed and re-used by others around the world.” IPTC Sport Schema can also be used for a more traditional model of aggregation and syndication by sports statistics providers who add value to the raw data being collected by sports leagues.

Like its ancestor SportsML, IPTC Sport Schema is created as a generic sports data model that can represent results, statistics, schedules and rosters across many sports. “Plugins” for specific sports extend the generic schema with specific statistics elements for 10 sports such as soccer, motor racing, tennis, rugby and esports. But the generic model can be used to handle any competitive sports competition, either team-based, head-to-head or individual.

As well as IPTC’s SportsML standard, the project is based on previous work by the BBC on its BBC Sport Ontology (some of its creators worked on this project). We have also consulted with and analysed related projects and formats such as OpenTrack and the IOC’s Olympics Data Feed format.

For more information on IPTC Sport Schema, please see the dedicated site sportschema.org, the project’s GitHub repository, 

Those who are interested in the details can see an introduction to the IPTC Sport Schema ontology design, the full ontology diagram or full RDF/OWL ontology documentation, 

There may be significant changes to the schema between now and when it is released as a fully endorsed IPTC Standard, so we don’t recommend that it is implemented in production systems yet. But we welcome analysis and experimentation with the model, and look forward to seeing feedback from those who would like to implement it in the real world.

People and organisations who are not IPTC members can give feedback by posting to the IPTC SportsML public discussion group or use the IPTC Contact Us form.
