The video recording of IPTC’s presentation at the Sports Video Group Content Management Forum has now been released.

Paul Kelly, Lead of the IPTC Sports Content Working Group, gave a live presentation introducing the IPTC Sport Schema to participants at the event, held in New York City in July 2023.

Many of those participants have helped with the development and testing of the new model for sports data, including PGA Tour, NBA, NFL, NHL and more.

The full video is now available on SVG’s on-demand video platform, SVG Play.

In the presentation, Paul describes among other things:

• the motivation for the new model
• how it is different from IPTC’s existing sports standard SportsML
• how it can handle sports from tennis to athletics to football to golf and more
• how it might be used by broadcasters and sports data providers to attach sports data to video and other forms of media content

The Sports Content Working Group is now putting the final touches to the schema and its supporting documentation before it is put to the IPTC Standards Committee to be turned into an official IPTC standard.

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.

In September 2022, IPTC Managing Director Brendan Quinn was invited to attended a workshop at the Royal Society in London, held in conjunction with the BBC. It was convened to discuss concerns about content provenance, threats to society due to misinformation and disinformation, and the idea of a “public-service internet.”

A note summarising the outcomes of the meeting has now been published. The Royal Society says, “This note provides a summary of workshop discussions exploring the potential of digital content provenance and a ‘public service internet’.”

The workshop note gives a summary of key takeaways from the event:

• Digital content provenance is an imperfect and limited – yet still critically important – solution to the challenge of AI-generated misinformation.
• A provenance-establishing system that can account for the international and culturally diverse nature of misinformation is essential for its efficacy.
• Digital content provenance tools present significant technical and ethical challenges, including risks related
  to privacy, security and literacy.
• Understanding how best to embed ideas such as digital content provenance into counter-misinformation strategies may require revisiting the rules which dictate how information is transmitted over the internet.
• A ‘public service internet’ presents an interesting and new angle through which public service objectives can shape the information environment; however, the end state of such a system requires greater clarity and should include a wide range of voices, including historically excluded groups.

The IPTC is already participating in several projects looking at concrete responses to the problems of misinformation and disinformation in the media, via our work theme on Trust and Credibility in the Media. We are on the Steering Committee of Project Origin, and work closely with C2PA and the Content Authenticity Initiative.

The IPTC looks forward to further work in this area.The IPTC and its members will be happy to contribute to more workshops and studies by the Royal Society and other groups.

The IPTC Standards Committee is happy to announce that ninjs, IPTC’s schema for marking up news content in JSON, has been revised to versions 2.1 and 1.5.

The vote to approve the new versions was taken at the recent IPTC Spring Meeting in Tallinn, Estonia and online.

This is in keeping with IPTC’s decision to maintain two parallel versions of ninjs: one for those who can’t upgrade to the 2.x version of backwards compatibility reasons, and those who prefer the simpler structure of ninjs 2.x that is easier to handle in some tools.

The ninjs User Guide has been updated to reflect the changes, which are summarised below.

ContactInfo added to ninjs 1.5 and 2.1

ninjs 2.1 and ninjs 1.5 both include the new contactinfo structure which can be used in the people, organisations, places and infosources properties (and their ninjs 1.x equivalents person, organisation, place and infosource).

The contactInfo structure can contain physical or online contact information such as a street address or postal address, a username on social media such as Twitter, Instagram or TikTok, or even a locator such as what3words.

Here are some examples of how the contactinfo property can be used:

"people": [
  {
    "name": "Jonas Svensson",
    "contactinfo": [
      {
        "type":"phone",
        "role": "work",
        "value": "+46 (0)8-7887500"
      }
    ]
  }
],

"organisations": [
  {
    "name": "International Committee of the Red Cross",
    "contactinfo": [
      {
        "type": "web",
        "value": "https://www.icrc.org/"
      },
      {
        "type": "address",
        "address": {
          "lines": [
            "19 Avenue de la paix",
            "1202 Geneva",
            "Switzerland"
          ]
        }
      },
      {
        "type": "telephone",
        "value": "+41 22 734 60 01"
      }
    ]
  }
]

Better support for organisation identifiers such as tickers, ISIN etc

ninjs 2.1 and 1.5 also include the new symboltype and symbol properties under symbols. Symbol can identify any type of URI describing the type of the symbol. The CV http://cv.iptc.org/newscodes/financialinstrumentsymboltype is recommended.

The ticker sub-property under symbols is now deprecated. This means that it can still be used if necessary, but use is not recommended.

We now recommend that ticker symbols are stored using symbol="TCKR" and symboltype="https://cv.iptc.org/newscodes/financialinstrumentsymboltype/Ticker".

Better support for machine classification

The subjects (ninjs 2.x) / subject (ninjs 1.x) properties now allow for the sub-properties creator, relevance and confidence. 

This allows organisations to more accurately use machine-generated subject tags in their content.  while stating that it was created by a machine (using the creator property), and giving numerical values for the relevance and confidence scores that are reported by machine tagging engines. (Of course, these properties can also be used for human-created subject tags if necessary!)

In addition, some internal changes to the schema were made to fix a validation bug that existed in previous versions. In order to accommodate these changes, the ninjs 2.1 schema uses the https://json-schema.org/draft/2020-12/schema version of JSON Schema.

Thanks to Johan Lindgren, welcome Ian Young as Working Group Lead

At the Spring Meeting in Tallinn we said farewell to Johan Lindgren as Lead of the News in JSON Working Group.

Johan, of the TT news agency in Sweden, was instrumental in bringing the News in JSON Working Group back from its quiet period after the initial launch of ninjs. This directly led to the release of several new versions of ninjs over the past few years, and its adoption by many of the world’s top news providers.

The IPTC wishes to thank Johan for all his contributions, and wishes him well for his retirement.

Johan’s work will be taken over by Ian Young from PA Media Group / Alamy based in the UK. Ian steps up to the Lead role after participating in the Working Group for many years, since the earliest days of ninjs.

We thank Ian for being willing to take on the lead role, and we look forward to seeing what developments will emerge from the News in JSON Working Group in the future.

In partnership with the IPTC, the PLUS Coalition has published for public comment a draft on proposed revisions to the PLUS License Data Format standard. The changes cover a proposed standard for expressing image data mining permissions, constraints and prohibitions. This includes declaring in image files whether an image can be used as part of a training data set used to train a generative AI model.

Review the draft revisions in this read-only Google doc, which includes a link to a form for leaving comments.

Here is a summary of the new property:

According to the PLUS proposal, the value of the property would be a value from the following controlled vocabulary:

The public comment period will close on July 20, 2023.

If it is accepted by the PLUS membership and published as a PLUS property, the IPTC Photo Metadata Working Group plans to adopt this new property into a new version of the IPTC Photo Metadata Standard at the IPTC Autumn Meeting in October 2023.

The IPTC is  happy to announce that NewsML-G2 version 2.32 has been released.

All documentation relating to version 2.32 can be found at the NewsML-G2 2.32 documentation page.

The changes in 2.32 are:

• Added new attributes authoritystatus and authoritystatusuri to the scheme, schemeMeta and catalog elements. These attributes describe the status of the authority managing a resource such as a scheme or a catalog.
• Added a new NewsCodes vocabulary https://cv.iptc.org/newscodes/authoritystatus with the values “No current authority”, “No single authority” and “Country-specific authority”.
• Updated the IPTC catalog to version 38, including the new authoritystatus vocabulary and also added a “cvx.iptc.org” vocabulary, ticker. Added an authoritystatusattribute to the following schemes: isin, a1312cat, a1312prio, a1312svc, a1312vers. Also update to note on the frmt vocabulary removing the part that says it is only applicable to NewsML 1.
• Update schema documentation for qcode, uri and literal throughout to be more accurate.
• Remove https from CV references in schema documentation
• Update dev schema to use 2.32.
• The schema documentation for “creator” and “creatoruri” attributes is now correct and consistent across all instances.

All information related to NewsML-G2 2.32 is at https://iptc.org/std/NewsML-G2/2.32/.

Example instance documents are at https://iptc.org/std/NewsML-G2/2.32/examples/. 

Full XML Schema documentation is located at https://iptc.org/std/NewsML-G2/2.32/specification/XML-Schema-Doc-Power/

The NewsML-G2 Generator tool has also been updated to produce NewsML-G2 2.32 files using the version 38 catalog.

For any questions or comments, please contact us via the IPTC Contact Us form or post to the iptc-newsml-g2@groups.io mailing list. IPTC members can ask questions at the weekly IPTC News Architecture Working Group meetings.

CIPA, the Camera and Imaging Products Association based in Japan, has released version 3.0 of the Exif standard for camera data.

The new specification, “CIPA DC-008-Translation-2023 Exchangeable image file format for digital still cameras: Exif Version 3.0” can be downloaded from https://www.cipa.jp/std/documents/download_e.html?DC-008-Translation-2023-E.

Version 1.0 of Exif was released in 1995. The previous revision, 2.32, was released in 2019. The new version introduces some major changes so the creators felt it was necessary to increment the major version number.

Fully internationalised text tags

In previous versions, text-based fields such as Copyright and Artist were required to be in ASCII format, meaning that it was impossible to express many non-English words in Exif tags. (In practice, many software packages simply ignored this advice and used other character sets anyway, violating the specification.)

In Exif 3.0, a new datatype “UTF-8” is introduced, meaning that the same field can now support internationalised character sets, from Chinese to Arabic and Persian.

Unique IDs

The definition of the ImageUniqueID tag has been updated to more clearly specify what type of ID can be used, when it should be updated (never!), and to suggest an algorithm:

This tag indicates an identifier assigned uniquely to each image. It shall be recorded as an ASCII string in hexadecimal notation equivalent to 128-bit fixed length UUID compliant with ISO/IEC 9834-8. The UUID shall be UUID Version 1 or Version 4, and UUID Version 4 is recommended. This ID shall be assigned at the time of shooting image, and the recorded ID shall not be updated or erased by any subsequent editing.

Guidance on when and how tag values can be modified or removed

Exif 3.0 adds a new appendix, Annex H, “Guidelines for Handling Tag Information in Post-processing by Application Software”, which groups metadata into categories such as “structure-related metadata” and “shooting condition-related metadata”. It also classifies metadata in groups based on when they should be modified or deleted, if ever.

Collaboration between CIPA and IPTC

CIPA and IPTC representatives meet regularly to discuss issues that are relevant to both organisations. During these meetings IPTC has contributed suggestions to the Exif project, particularly around internationalised fields and unique IDs.

We are very happy for our friends at CIPA for reaching this milestone, and hope to continue collaborating in the future.

Developers of photo management software understand that values of Exif tags and IPTC Photo Metadata properties with a similar purpose should be synchronised, but sometimes it wasn’t clear exactly which properties should be aligned. IPTC and CIPA collaborated to create a Mapping Guideline to help software developers implement it properly. Most professional photo software now supports these mappings.

Complete list of changes in Exif 3.0

The full set of changes in Exif 3.0 are as follows (taken from the history section of the PDF document):
