We had a great Photo Metadata Conference last Thursday. Thanks to those who attended. For those who didn’t, or those who would like to go over some detail again, here we publish full recordings of all sessions.
First up, Brendan Quinn, IPTC Managing Director introduced the day and gave an overview of what was to come:
Next was a great panel on adoption of the accessibility properties added in the 2021.1 update to the IPTC Photo Metadata Standard. We are very happy to share that the fields are now supported in many popular photo creating and editing tools, with more to come:
Next was David Riecks and Michael Steidl, co-leads of the IPTC Photo Metadata Working Group, presenting the work done by the Working Group since the last Photo Metadata Conference:
Then came a session on real-world implementations of the C2PA specification for content authenticity, including presentations from Microsoft, CBC / Radio Canada, the BBC and Adobe / Content Authenticity Initiative:
The last session was a panel discussion on Metadata for AI Images, looking at questions around the ethics of using copyrighted content to train a machine learning engine to generate AI images, and how the IPTC Photo Metadata Standard could be extended to support metadata appropriate for AI-generated images:
We had a great session and a packed conference! We look forward to seeing everyone again at next year’s event.
Today, the IPTC announces the release of the IPTC Photo Metadata Standard, version 2022.1.
The update has some changes to align the IPTC Photo Metadata Standard more closely which IPTC Video Metadata Hub, which helps with the integration into the C2PA specification as announced earlier this week.
The changes will be presented today (Thursday 10 November) at the IPTC Photo Metadata Conference, alongside sessions on AI and images, C2PA, and accessibility. You can still register for today’s Photo Metadata Conference, for free, at the IPTC Photo Metadata Conference 2022 event page. Video recordings from the event will be posted in the coming weeks.
The changes in detail
The IPTC Core schema has been updated to version 1.4, including the following changes:
-
Name of property Source changed to Source (Supply Chain)
-
Property Subject Code was set to legacy state
The IPTC Extension schema has been updated to version
-
New property Contributor (matching the equivalent property in IPTC Video Metadata Hub)
-
The property structure for Product has been extended with a new property Identifier
The specification document has also been updated with some edits and additions to Help Texts and User Notes.
Technical Reference update
The IPTC Photo Metadata TechReference has also been updated to include the changes in version 2022.1. This can be used by software makers to easily include the changes in the new version.
For more information on how to use the Technical Reference, please consult the IPTC Photo Metadata Technical Reference documentation.
Questions? Comments?
For any questions or comments on this update or on the IPTC Photo Metadata Standard in general, please post to the public IPTC Photo Metadata forum at iptc-photometadata@groups.io.

We are happy to announce that IPTC’s work with C2PA, the Coalition for Content Provenance and Authority, continues to bear fruit. The latest development is that C2PA assertions can now include properties from both the IPTC Photo Metadata Standard and our video metadata standard, IPTC Video Metadata Hub.
Version 1.2 of the C2PA Specification describes how metadata from either the photo or video standard can be added, using the XMP tag for each field in the JSON-LD markup for the assertion.
For IPTC Photo Metadata properties, the XMP tag name to be used is shown in the “XMP specs” row in the table describing each property in the Photo Metadata Standard specification. For Video Metadata Hub, the XMP tag can be found in the Video Metadata Hub properties table under the “XMP property” column.
We also show in the example assertion how the new accessibility properties can be added using the Alt Text (Accessibility) field which is available in Photo Metadata Standard and will soon be available in a new version of Video Metadata Hub.

We are proud to announce that Camera Bits, Mobius Labs, Microsoft, Smithsonian, CBC and many others will be presenting at the IPTC Photo Metadata Conference next week, Thursday 10th November. With a theme of Photo Metadata in the Real World, the event is free for anyone to attend. Register here for the Zoom webinar to receive details before the event.
The event will run from 1500 UTC to 1800 UTC. The full agenda with timings is published on the event page.
We will start off with a short presentation on recent updates to the IPTC Photo Metadata Standard from David Riecks and Michael Steidl, co-leads of the IPTC Photo Metadata Working Group. This will include the new properties approved at the recent IPTC Autumn Meeting.
A session on Adoption of IPTC Accessibility properties will include speakers from Smithsonian, Camera Bits (makers of the photographers tool Photo Mechanic), Picvario presenting their progress implementing IPTC’s accessibility properties, announced at last year’s Photo Metadata Conference.
The next session will be Software Supporting the IPTC Photo Metadata Standard, where Michael Steidl and David Riecks, co-leads of the IPTC Photo Metadata Working Group, present their work on IPTC’s database of software supporting the Photo Metadata Standard, and the IPTC Interoperability tool, showing compatibility between tools for individual properties.
Use of C2PA in real-world workflows is the topic of the next session, demonstrating progress made in implementing C2PA technology to make images and video tamper-evident and to establish a provenance trail for creative works. Speakers include Nigel Earnshaw and Charlie Halford from the BBC, David Beaulieu and Jonathan Dupras from CBC/Radio Canada, Jay Li from Microsoft, and a speaker yet to be confirmed from the Content Authenticity Initiative.
The next session should be very exciting: Metadata for AI images will be the topic, featuring an introduction to synthetic media and “generative AI” images, including copyright and ownership issues behind the images used to train the machine learning models involved, from Brendan Quinn and Mark Milstein.
Then we have a panel session: How should IPTC support AI and generative models in the future? Questions to be covered include whether we should identify which tool, text prompt and/or model was used to create a generative image? Should we include a flag that indicates content was created using a “green”, copyright-cleared set of training images? And perhaps other questions too – please come along to ask your own questions! Speakers include Dmitry Shironosov, Everypixel / Dowel.ai / Synthetics.media, Martin Roberts from Mobius Labs and Sylvie Fodor from CEPIC. The session will be moderated by Mark Milstein from vAIsual.
Last year we had over 200 registrants and very lively discussions. We look forward to even more exciting presentations and discussions this time around! See you there. (Please don’t forget to register!)

The IPTC Photo Metadata Working Group is proud to announce the IPTC Photo Metadata Conference 2022. The event will be held online on Thursday November 10th from 15.00 – 18.00 UTC.
This year the theme is Photo Metadata in the Real World. After introducing two new developments last year: the IPTC Accessibility properties and the C2PA specification for embedding provenance data in photo and video content – we re-visit both technologies to see how they are being adopted by software systems, publishers and broadcasters around the world.
The 3-hour meeting will host four sessions:
- Adoption of the IPTC Accessibility Properties – we hear from vendors and content creators on how they are progressing in implementing the new properties to support accessibility
- Software Supporting the IPTC Photo Metadata Standard – showcasing an update to IPTC’s directory of software supporting the IPTC Photo Metadata Standard, including field-by-field reference tables letting users compare software implementations
- Use of C2PA in real workflows – showcasing early work on implementing the C2PA specification in media organisations
- Artificial Intelligence and metadata – looking at the questions around copyright and synthetic media: for example, when generative AI uses thousands of potentially copyrighted images to train machine learning models, who owns the resulting images?
We look forward to welcoming all interested parties to the conference – no IPTC membership is needed to attend. The event will be held as a Zoom webinar.
Please see more information and the Zoom registration link on the event page.
See you there on the November 10th!

Last week the IPTC held its Autumn Meeting 2022, with over 70 attendees from over 20 countries attending the three-day online event.
Discussions were as wide-ranging as ever. Highlights were a guest presentation on how media organisations can prepare for the Metaverse from startup advisor and previous member of the Microsoft HoloLens team, Toby Allen; intense discussions from members about making our work in machine-readable rights and RightsML simpler and more accessible and to bridge the gap between our simple, lightweight JSON news standard ninjs and our richly structured full-featured XML-based standard NewsML-G2.
We also heard about many other topics:
- Meinolf Ellers at IPTC member dpa spoke about the DRIVE initiative, which follows on from the C-POP project that IPTC advised on in 2019 and 2020. DRIVE allows consortium members to share data about content usage to drive subscriptions and engagement, and to find under-represented areas in their news output to meet audience needs.
- We heard about representing social media content in NewsML-G2: Dave Compton of Refinitiv spoke about their work encoding content from Twitter and other social networks in NewsML-G2 format for re-use, enhancement and syndication.
- Will Kreth, previously CEO of EIDR, spoke about the HAND project which aims to create a unique identifier for media and sports talent
- Fredrik Lundberg from IPTC member iMatrics and guest presenter Jens Pehrson from GOTA Media spoke about a new tool they have developed that allows publishers to track the gender balance in their news content
- Johan Lindgren from IPTC member TT (the Swedish national news agency) spoke about their recent project to develop a classification and entity extraction engine for their news content, based on IPTC Media Topics taxonomy
- We heard from Audren Layeux of CARSA who spoke about the European Media Data Space project, an EU initiative
- Ben Colman, CEO of RealityDefender spoke (direct from TechCrunch Disrupt in San Francisco!) about their deepfake detection technology, used by social media networks, financial institutions and media organisations to detect manipulated images and videos.
- IPTC MD Brendan Quinn spoke about IPTC’s ongoing work with C2PA and Project Origin, including forthcoming additions to C2PA to include video metadata.
In addition, we heard updates from all IPTC Working Groups: Dave Compton introduced NewsML-G2 2.31; Paul Kelly spoke about some new developments in the RDF-based sports data model which will be announced soon; Pam Fisher described the work of the Video Metadata Working Group and the changes coming in Video Metadata Hub v1.4; David Riecks and Michael Steidl spoke about Photo Metadata Standard 2022.1 and the ongoing work of the Photo Metadata Working Group;
The Standards Committee voted in new standard versions: NewsML-G2 v2.31, Video Metadata Hub v1.4, and Photo Metadata Standard 2022.1. These will be released and publicised over the coming weeks.
The IPTC Annual General Meeting 2022 saw Johan Lindgren step down from the Board of Directors after 6 years of service. Thanks very much for all your help, Johan!
We are very happy to welcome a new Board member: Heather Edwards of Associated Press.
Thanks very much to everyone who attended and spoke. You contributed to making it a great event for all!
As usual, full recordings of all sessions are available to IPTC members on the members-only event page.

- irel:wasPackagedIn: “Indicates that this Item was included in the target package”
Thanks to everyone from IPTC members and users of the NewsCodes CV for suggesting terms, and to the NewsCodes and Sports Content Working Groups who helped to put this release together.
Alamy, a stock photo agency offering a collection of over 300 million images along with millions of videos, has recently launched a new Partnerships API, and has chosen IPTC’s ninjs 2.0 standard as the main format behind the API.
Alamy is an IPTC member via its parent company PA Media, and Alamy staff have contributed to the development of ninjs in recent years, leading to the introduction of ninjs 2.0 in 2021.
“When looking at a response format, we sought to adopt an industry standard which would aid in the communication of the structure of the responses but also ease integration with partners who may already be familiar with the standard,” said Ian Young, Solutions Architect at Alamy.

“With this in mind, we chose IPTCs news in JSON format, ninjs,” he said. “We selected version 2 specifically due to its structural improvements over version 1 as well as its support for rights expressions.”
Young continued: “ninjs allows us to convey the metadata for our content, links to the media itself and the various supporting renditions as well as conveying machine readable rights in a concise payload.”
“We’ve integrated with customers who are both familiar with IPTC standards and those who are not, and each have found the API equally easy to work with.”
Learn more about ninjs via IPTC’s ninjs overview pages, consult the ninjs User Guide, or try it out yourself using the ninjs generator tool.
Family Tree magazine has published a guide on using embedded metadata for photographs in genealogy – the study of family history.
Rick Crume, a genealogy consultant and the article’s author, says IPTC metadata “can be extremely useful for savvy archivists […] IPTC standards can help future-proof your metadata. That data becomes part of the digital photo, contained inside the file and preserved for future software programs.”
Crume quotes Ken Watson from All About Digital Photos saying “[IPTC] is an internationally recognized standard, so your IPTC/XMP data will be viewable by someone 50 or 100 years from now. The same cannot be said for programs that use some proprietary labelling schemes.”
Crume then adds: “To put it another way: If you use photo software that abides by the IPTC/XMP standard, your labels and descriptive tags (keywords) should be readable by other programs that also follow the standard. For a list of photo software that supports IPTC Photo Metadata, visit the IPTC’s website.“
“[IPTC] is an internationally recognized standard, so your IPTC/XMP data will be viewable by someone 50 or 100 years from now”
The article goes on to recommend particular software choices based on IPTC’s list of photo software that supports IPTC Photo Metadata. In particular, Crume recommends that users don’t switch from Picasa to Google Photos, because Google Photos does not support IPTC Photo Metadata in the same way. Instead, he recommends that users stick with Picasa for as long as possible, and then choose another photo management tool from the supported software list.
Similarly, Crume recommends that users should not move from Windows Photo Gallery to the Windows 10 Photos app, because the Photos app does not support IPTC embedded metadata.
Crume then goes on to investigate popular genealogy sites to examine their support for embedded metadata, something that we do not cover in our photo metadata support surveys.

In a related tool update announcement, we have now added a handy “show retired terms” checkbox to the Media Topics interactive tree browser tool, and we default to only showing the active (non-retired) terms. The new option can be seen in the picture at the top of this article.
Digital Source Type vocabulary updates
After asking for feedback on a draft of the work a few months ago, we have updated the Digital Source Type vocabulary to support the emerging area of “Synthetic Media.”
The single term “softwareImage” has been retired, which means that while it is acceptable in legacy content, we no longer recommend its use. The term is now replaced with 9 new terms covering the spectrum from purely human creation through to purely machine image creation:
- Original media with minor human edits
- Composite of captured elements
- Algorithmically-enhanced media
- Data-driven media
- Digital art
- Virtual recording
- Composite including synthetic elements
- Trained algorithmic media
- Pure algorithmic media
- RETIRED: Created by software
To see more detail including the definition of each term, click the links above or view the entire IPTC Digital Source Type vocabulary.
Thanks to those both inside and outside of the IPTC community who gave feedback on our original proposal, your comments were very much appreciated.
Subject Code vocabulary updates – indicating its deprecated status
The IPTC Subject Code vocabulary was created over twenty years ago, in the year 2000. It was maintained through to 2010, but at that point the Media Topic vocabulary took over as IPTC’s preferred subject classification taxonomy. We will keep it on our vocabulary server, but we no longer recommend its use in projects due to some terms being out of date.
So we have put warnings on the pages of the Subject Code vocabulary that indicate its deprecated nature, and encourage users to look at Media Topic instead.
As always, the Media Topics vocabularies can be viewed in the following ways:
- In a collapsible tree view
- As a downloadable Excel spreadsheet
- On one page on the cv.iptc.org server
- In machine readable formats such as RDF/XML and Turtle using the SKOS vocabulary format: see the cv.iptc.org guidelines document for more detail.
