As previously announced, the IPTC are participating in the Coalition for Content Provenance and Authenticity (C2PA) project to create a specification to tackle online disinformation and misinformation.
After months of work by the C2PA Technical Working Group, the first public draft of the specification has been released. In particular, the spec defines how properties from the IPTC Photo Metadata Standard can be included in a C2PA manifest, creating a provenance trail that allows future viewers to validate the authenticity of a claim associated with a media asset (such as the location the photo was taken, the creator’s name or who is the person in a photo).
The full press release from C2PA follows:
SAN FRANCISCO, Calif. — September 1, 2021 — Today, the Coalition for Content Provenance and Authenticity (C2PA), a Joint Development Foundation project established to scale trust in online content, released its content provenance specifications – in draft form – for community review and feedback. Driven by a commitment to tackle online disinformation, the C2PA’s technical specifications are designed to be an open standard that will allow publishers, creators and consumers to trace the origin and evolution of a piece of media, including images, videos, audio and documents.
“C2PA was established to accelerate progress toward the broad adoption of content provenance standards that will enable a future of verifiable integrity in media,” said Andrew Jenks, C2PA Chair. “The release of this draft is an exciting and important milestone, representing a diverse and collaborative effort across industries to protect people from fabricated and manipulated media and drive transparency in the origin and history of content.”
Combatting online content fraud at scale requires transparency and an accessible and open approach that enables consumers to make informed decisions about what has been modified and what has not. The C2PA was launched in February 2021 with founding members Adobe, Arm, BBC, Intel, Microsoft and Truepic with the goal of developing an end-to-end open technical standard to address the rise of disinformation efforts leveraging tools for media fabrication and manipulations. The effort has expanded, bringing in additional members including Twitter, WITNESS, Akamai and Fastly.
Over the past six months, the C2PA has worked with industry experts and partner organizations, including the Project Origin Alliance and the Content Authenticity Initiative (CAI), to develop a standard for digital provenance that provides platforms with a method to define descriptive metadata, what information is associated with each type of asset, how that information is presented and stored, and how evidence of tampering can be identified. This group of contributors spans a spectrum of industries including social media, news publishing, software technology, semiconductors and more. All have contributed to building these new technical specifications through a process of gathering requirements, considerations of scenarios and technical design.
Following the review period, the C2PA working groups will finalize the 1.0 version of the technical standards and once published, the group will pursue adoption, prototyping and communication through coalition members and other external stakeholders, providing the foundation for a system of verifiable provenance on the internet.
“The power of C2PA’s open standard will rely on its broad adoption by producers and custodians of content, which makes this review phase so critical to the development and finalization of the specifications,” said Jenks. “This is why we are making the draft specification available to the public. We encourage rigorous review and feedback across industries, civil society, academia, and the general public to ensure the C2PA standards reflect the complex nature of this effort.”
The draft specification can be accessed through the C2PA website, and comments will be accepted through a web submission form and GitHub until November 30, 2021.

About C2PA
The Coalition for Content Provenance and Authenticity (C2PA) is an open, technical standards body addressing the prevalence of misleading information online through the development of technical standards for certifying the source and history (or provenance) of media content. C2PA is a Joint Development Foundation project, formed through an alliance between Adobe, Arm, BBC, Intel, Microsoft and Truepic. For more information, visit c2pa.org.
The IPTC Photo Metadata Standard is widely used by photographers, photo agencies and other photo suppliers around the world. To help photo people use it properly, IPTC has a specification document with a lot of details in document form.
Now, we have released a machine-readable version of the spec that can be consumed directly by software tools.
We call it the IPTC Photo Metadata TechReference. (See below for direct links to the data files.)
The TechReference is a data object containing all the details of the IPTC Photo Metadata technical specifications in the easy-to-use JSON and YAML formats.
The file covers all IPTC properties and structures.
For each property, we specify:
- the property’s formal name
- corresponding identifiers in the ISO XMP and the IPTC IIM formats, if applicable;
- the property’s datatype, such as string, number or a custom property structure like Location; and
- the property identifier that can be used with ExifTool to read or write the metadata property (such as “XMP-dc:creator” for XMP or “IPTC:Creator” for IIM);
- … and a few more details.
We have also published rich documentation about the TechReference data object on the IPTC website. The data objects themselves can be downloaded from the IPTC site by both IPTC members and other interested parties.

Today we announce the launch of two new browser extensions for viewing IPTC Photo Metadata on web pages.
The GetPMD tool is one of IPTC’s most popular online resources. With the GetPMD tool, users can view the embedded IPTC metadata of any image on the web, whether it was embedded using either the IPTC IIM or the ISO XMP format. But up to now, users must copy and paste an image’s URL into the tool, or install a browser “bookmarklet”.
To make that a little bit easier, we have created the IPTC Photo Metadata Inspector, a simple browser extension that currently works with the Google Chrome and Mozilla Firefox browsers.
With the extension installed, a context menu will appear when you right-click on an image anywhere on the Web, with a menu option, “View IPTC Photo Metadata.” If you select that option, you will be taken to getpmd.iptc.org where you can see the embedded metadata for that image.
Please note that the Photo Metadata Inspector only works with simple images: it won’t work with embedded video thumbnails or tweets, for example.
The browser extensions are open source, the code is available from the IPTC’s GitHub repository.
Ideas for fixes and new features are welcome.
If you have feedback, please raise an issue on our GitHub repository, post suggestions to the iptc-photometadata@groups.io public discussion list, or contact us via the form on this site.
schema.org is the technology used by web site owners around the world to make metadata available to search engines and other third-party services. It is widely used to embed machine-readable data in websites for products, store opening times and much more.
It is also used as one of the sources of metadata for the Google search results. The schema.org “license”, “acquireLicensePage” and “creator” properties in a page’s HTML code are used in addition to IPTC Photo Metadata embedded in image files to populate the image panel.
schema.org version 11 was released this week. It contains two new properties on the CreativeWork type (and therefore its subtypes such as ImageObject) that were created to match their equivalent properties in IPTC Photo Metadata: copyrightNotice, which matches the IPTC Photo Metadata Copyright Notice property, and creditText, which matches the IPTC Photo Metadata Credit Line property.
The new fields are not yet supported by Google images search, but hopefully will be soon.
After the recent update, the current properties mapped to schema.org and used in Google images search results are:
| IPTC Photo Metadata property | Matching schema.org property | Used in Google search results? |
| Creator | ImageObject -> creator | Yes |
| Copyright Notice | ImageObject -> copyrightNotice | Not yet |
| Credit Line | ImageObject -> creditText | Not yet |
| Web Statement of Rights | ImageObject -> license | Yes |
| Licensor / Licensor URL | ImageObject -> acquireLicensePage | Yes |
The IPTC Photo Metadata Working Group is working on a more comprehensive document showing all possible IPTC Photo Metadata fields with their schema.org and EXIF equivalents. The full mapping document will be released soon.
Yesterday Michael Steidl, Lead of the IPTC Photo Metadata Working Group, gave a webinar to Bundesverband professioneller Bildanbieter (BVPA), the Federal Association of Professional Image Providers in Germany.
The webinar focused on the recently introduced image license information for Google image searches and the possible opportunities and risks for the professional image business.
“This year, Google introduced the so-called Licensable Badge for its image search. This feature enables images to be linked to license information and to be displayed in the image search results with a corresponding link. Image seekers from advertising, editorial offices and corporate PR can follow the link to obtain further information on how to use the image. This turns Google image search into a potential marketplace. But how can image providers use the new tool for themselves? Is it worth the effort of storing the necessary metadata? Are there any economic risks involved? Will Google soon become a meta picture agency?”
In the first part of the webinar, Michael Steidl explained which image metadata must be stored in order to display photo credits and “licensable” badges on Google. He also informed participants about the problem that certain software and web platforms deletes image metadata after upload.
In the second part, Alexander Karst explains the possibilities for increasing visibility through the new features and gives an assessment of the effects on the image market.
Thanks to BVPA for hosting Michael for the webinar.
We’re very happy that we can make public some of the video recordings from the recent IPTC Photo Metadata Conference 2020, held on Tuesday 13 October 2020.
Thanks to all who attended – we had over 200 registrations for the webinar.

Introduction
Brendan Quinn, Managing Director of IPTC, opened the day with an introduction to IPTC and an overview of what was to come (10 minutes):
Michael Steidl, Photo Metadata WG lead on IPTC Photo Metadata
Michael Steidl presented on why we should care about photo metadata in his presentation “About IPTC Photo Metadata” (48 minutes including Q&A)
Google’s Licensable Images features
Francois Spies, a Product Manager for Google Images in Mountain View, presented on the Licensable Images features which they developed in consultation with IPTC this year.
After Francois’ presentation, Matthew O’Such, VP SEO for Getty Images and Marcin Czyzewski, CTO and Picturemaxx joined us to share their views on implementing the changes to IPTC Photo Metadata required to power the Google Licensable Images feature. Then we had a Q&A session including Michael, Francois, Matthew and Marcin.
Unfortunately, Google asked us not to make a recording of their presentation or the panel available. However the resources that Francois shared are all available via our Quick Guide to IPTC Photo Metadata and Google Images.
Andy Parsons on the Content Authenticity Initiative
Next up, Andy Parsons (Adobe) introduced the Content Authenticity Initiative (47 minutes including Q&A and a wrap-up of the day from Brendan Quinn):
Thanks again to all our speakers and panellists for their contributions. We’re already looking forward to next year’s event!
Currently next year’s IPTC Photo Metadata Conference is scheduled to be in late May 2021 in Mallorca, Spain in conjunction with the CEPIC Congress 2021. If that proves impractical then we will host another online event.
We are very happy to announce that this year’s IPTC Photo Metadata Conference will be conducted fully online, and for the first time ever, is free for all to attend.
This year’s conference takes place on Tuesday October 13, 2020 from 15:00 – 18:00 UTC time (see times in other timezones below).
We have some very special guests for this year’s conference:
Michael Steidl, Lead of the IPTC Photo Metadata Working Group, will introduce IPTC Photo Metadata, and discuss recent developments, and what we see in the future of photo metadata.
Francois Spies, Product Manager, Google Images will present Google’s recent work on the “Licensable Images” project, which adds a “licensable” badge to images in Google search results, and links from the image preview panel in search results pages directly back to a place where users can obtain a licence to re-use the image.
Andy Parsons, Director of Content Authenticity Initiative, Adobe will present the Content Authenticity Initiative, which is “designing components and drafting standards specifications for a simple, extensible and distributed media provenance solution.”
How will the Content Authenticity Initiative work? What work has been done so far and what still needs to be done? How can you help?
Please register here via Zoom – it’s free!
The IPTC Photo Metadata Conference has been held in conjunction with the CEPIC Congress for many years. The 2020 CEPIC Congress has been postponed to 19 to 21 May 2021, but with so much going on in the world of image metadata, we didn’t want to miss out on the opportunity, so we are holding a virtual event this year. We look forward to joining CEPIC again next year, hopefully in Mallorca in May 2021.

The IPTC is very happy to announce that as a result of our collaboration with Google and CEPIC, Google Images’s new licensable badge and other related features are now live.
This means that when photo owners include a photograph’s Web Statement of Rights (also known as Copyright Info URL) in an image’s embedded metadata, Google will display a “Licensable” badge on the image in Google Images search results and the image will appear when the “View all images with Commercial or other licenses” filter is selected. If the Licensor URL is also added, Google will feature a “get this image on” link that takes users directly to a page on the photo owner’s site enabling the user to easily obtain a license to re-use the image elsewhere.
The launch on Google Images comprises three different components:
- “Licensable” badge on image search results for images that have the required metadata fields
- Two new links in the Image Viewer (the panel that appears when a user selects an image result) for people to access the image supplier’s licensing information, namely:
- A “License details” link. This directs users to a page defined by the image supplier explaining how they can license and use the image responsibly
- A “Get this image on” link, which directs users to a page from the image supplier where users can directly take the necessary steps to license the image
- A “License details” link. This directs users to a page defined by the image supplier explaining how they can license and use the image responsibly
- A Usage Rights drop-down filter in Google Image search results pages to support filtering results for Creative Commons, commercial, and other licenses.
“As a result of a multi-year collaboration between IPTC and Google, when an image containing embedded IPTC Photo Metadata is re-used on a popular website, Google Images will now direct interested users back to the supplier of the image,” said Michael Steidl, Lead of the IPTC Photo Metadata Working Group. “This is a huge benefit for image suppliers and an incentive to add IPTC metadata to image files.”
The features have been in beta since February, and after extensive testing, refinement and discussion with IPTC, CEPIC and others, Google is rolling out the new features this week.
As we describe in the Quick guide to IPTC Photo Metadata and Google Images, image owners can choose from two methods to enable the Licensable badge and “Get this image” link: embedding IPTC metadata in image files, or including structured schema.org metadata in the HTML of the web page hosting the image.
Of the two approaches, using embedded IPTC metadata has two benefits. Firstly, the embedded metadata stays with the image even when it is re-used, so that the Licensable badge will appear even when the image is re-published on another website.
Secondly, the “Creator”, “Copyright” and “Credit” messages are only displayed in search results when they are declared using embedded IPTC metadata.
“The IPTC anticipates that this will lead to increased awareness of image ownership, copyright and licensing issues amongst content creators and users,” said Brendan Quinn, Managing Director of IPTC. “By providing direct leads to image owners’ websites, we hope that this leads to increased business for image suppliers both large and small.”
The Google announcements can be found here:
Previously, we shared that Google was making image credits and usage rights information more visible on Google Images. Google now displays information about image copyright and ownership details, alongside creator and credit info, when websites and photo-owners make that information available for Google to crawl. Since the announcement there has been steady growth in the amount images containing these embedded metadata fields, which in turn has helped drive greater user awareness of copyright for images on the internet.
Up to now, users have seen the IPTC metadata information when they click on the “Image Credits” link in the “Google Images viewer” – the panel that appears when a user selects an image. Starting from today, users will begin to see this information directly in the viewer, making this rights-related information even more visible.
You can see an example of what this looks like below:
The Google Images team has said in a statement: “We are committed to helping people understand the nature of the content they’re looking at on Google Images. This effort to make IPTC-related information more visible is one more step in that direction.”
For more information on how you can embed rights and credits metadata in your photos, please see our Quick Guide to IPTC Photo Metadata and Google Images.
If you create photo editing or manipulation software and are looking for more information, please consult the Quick Guide or contact us for more information and advice.
We are very happy to continue working with Google and our partner organisation CEPIC on this and other developments in this area. We look forward to making an announcement about the launch of the related “Licensable Images” feature over the summer.
Last week IPTC did something we had never tried before: we ran a complete three-day member meeting virtually, using videoconferencing, which worked very well! Thanks to all our participants and presenters.
Spread over three days, over 50 attendees from the majority of IPTC member organisations across 16 countries heard over 20 presentations from IPTC Working Groups, IPTC member organisations and invited speakers on topics from AI-generated stock photography to tracking entities in news stories. The culmination of the event was the approval of new versions of ninjs, NewsML-G2 and Video Metadata Hub, and the (re-)election of Robert Schmidt-Nia as Chair of IPTC.
Monday: Photo Metadata, Sport and Web Publications
Monday set the tone with an introduction from IPTC Managing Director Brendan Quinn, and introductions from all attendees. Michael Steidl gave the first Working Group update as Lead of the Photo Metadata Working Group, covering the group’s wide-ranging work over the past six months including releasing the Photo Metadata Standard 2019.1 including Image Regions, plus partnership projects with Google on exposing embedded IPTC Photo Metadata fields in search results, and emerging work with camera industry association CIPA and schema.org.
Laurent Le Meur, previous IPTC board member and currently CTO at EDRLab, gave a thought-provoking presentation on W3C Web Publications spec and how it might apply to the news publishing industry. Paul Kelly, lead of the Sports Content Working Group presented his group’s investigations into semantic modelling for sports content, looking at existing sports models and current projects investigating schema.org and semantic / linked-data modelling of sports information, which will feed in to an upcoming version of SportsML.
Tuesday: NewsML-G2, ninjs, Robojournalism, AI, Blockchain, Trust and Video
Tuesday was a busy day: we started with Dave Compton from Refinitiv, lead of the NewsML-G2 Working Group, presenting the group’s latest work including their proposal for NewsML-G2 2.29. Johan Lindgren of TT and lead of the News in JSON Working Group presented a proposal for ninjs 1.3, including many updates suggested by users and the community.
Ed Boyling of Thomson Reuters demonstrated a tool called Lynx Insights that is used by TR to generate news stories based on a rich set of rules defined by journalists. After a rule is created, an incoming news event (such as a company publishing a set of financial results) can automatically be converted to a readable story published on the wire within seconds.
Tao Chen of 500px (part of IPTC member Visual China Group) and lead of the AI Expert Group presented their latest work on AI for images, including automatic quality detection, face anonymisation, subjective feature detection (photos about “happiness” or “romance”), moving from simple face detection to age, gender and celebrity detection, automatic cutouts and more.
Angelo Marrara of ANSA and some project colleagues from EY presented their work on ANSACheck, a way of ensuring that content matches what the agency originally published using blockchain technology. The project has launched and you can see the tool embedded on ANSA’s pages.
Brendan Quinn presented IPTC’s latest work on trust and credibility in the news, including the IPTC Trust and Credibility Guidelines document draft that was published recently.
Finally, Pam Fisher of the Video Metadata Working Group presented the group’s proposal for Video Metadata Hub version 1.3, an update to clarify and simplify some points and take on some suggestions from the community.
Wednesday: NewsCodes translations, Entities, Standards Committee and IPTC Election
Wednesday started off with Jennifer Parrucci of New York Times, lead of IPTC’s NewsCodes Working Group, presenting the group’s work since the last meeting, announcing translations of the core Media Topics controlled vocabulary into Danish, Simplified Chinese and Norwegian. We now publish Media Topics in 11 languages!
Christoffer Nilsson of new IPTC member iMatrics and Joacim Ståhl of Elysium AI (part of TT) both gave presentations on their work on extracting entities (people, places, organisations and objects) from news content, and we discussed the possibility of working as a group on an industry-wide “news entities” database.
The Spring 2020 IPTC Standards Committee Meeting was led by Stéphane Guérrilot of AFP, Chair of the Standards Committee. The first part of the meeting was a wide-ranging discussion on “how to make IPTC standards easier to use”, which will lead to some interesting projects in the next few months on documentation, marketing materials, and open source software. The second part of the meeting was the formal IPTC member vote on the proposed new standard versions: we are pleased to say that ninjs 1.3, NewsML-G2 2.29 and Video Metadata Hub 1.3 were all approved!
Finally we held a General Meeting of IPTC voting Members, during which Robert Schmidt-Nia of DATAGROUP Consulting Services was elected as IPTC Chair. We also voted through a change to IPTC’s official Articles of Association, introducing a new membership category. More on this in coming weeks!
Thanks again to everyone who made our first fully virtual member meeting such a a great success!
