Crossref and the Public Knowledge Project (PKP) have been working closely together for many years, sharing resources and supporting our overlapping communities of organisations involved in communicating research. Now we’re delighted to share that we have agreed on a new set of objectives for our partnership, centred on further development of the tools that our shared community relies upon, as well as building capacity to enable richer metadata registration for organisations using the Open Journal Systems (OJS).
To mark Crossref’s 25th anniversary, we launched our first Metadata Awards to highlight members with the best metadata practices.
GigaScience Press, based in Hong Kong, was the leader among small publishers, defined as organisations with less than USD 1 million in publishing revenue or expenses. We spoke with Scott Edmunds, Ph.D., Editor-in-Chief at GigaScience Press, about how discoverability drives their high metadata standards.
What motivates your organisation/team to work towards high-quality metadata? What objectives does it support for your organisation?
Our objective is to communicate science openly and collaboratively, without barriers, to solve problems in a data- and evidence-driven manner through Open Science publishing. High-quality metadata helps us address these objectives by improving the discoverability, transparency, and provenance of the work we publish. It is an integral part of the FAIR principles and UNESCO Open Science Recommendation, playing a role in increasing the accessibility of research for both humans and machines. As one of the authors of the FAIR principles paper and an advisor of the Make Data Count project, I’ve also personally been very conscious to practice what I preach.
On behalf of the Nominating Committee, I’m pleased to share the slate of candidates for the 2025 board election.
Each year we do an open call for board interest. This year, the Nominating Committee received 51 submissions from members worldwide to fill five open board seats.
We have four large member seats and one small member seat open for election in 2025. We maintain a balanced board of 8 large member seats and 8 small member seats. Size is determined based on the organization’s membership tier (small members fall in the $0-$1,650 tiers and large members in the $3,900 - $50,000 tiers).
In 2022, we wrote a blog post “Rethinking staff travel, meetings, and events” outlining our new approach to staff travel, meetings, and events with the goal of not going back to ‘normal’ after the pandemic and said that in the future we would report on our efforts to balance online and virtual events, work life balance for staff, and track our carbon emissions. In December 2024, we wrote a blog post, “Summary of the environmental impact of Crossref,” that gave an overview of 2023 and provided the first report on our carbon emissions. Our report on 2023 only just made it into 2024, so we are happy to report on 2024 a little sooner in the year.
The Crossmark button gives readers quick and easy access to the current status of an item of content, including any corrections, retractions, or updates to that record.
Crossmark provides a cross-platform way for readers to quickly discover the status of a research output along with additional metadata related to the editorial process. Crucially, the Crossmark button can also be embedded in PDFs, which means that members have a way of alerting readers to changes months or even years after it’s been downloaded.
Research doesn’t stand still: even after publication, articles can be updated with supplementary data or corrections. It’s important to know if the content being cited has been updated, corrected, or retracted. Crossmark makes this information more visible to readers. With one click, you can see if content has changed, and access valuable additional metadata provided by the member, such as key publication dates (submission, revision, acceptance), plagiarism screening status, and information about licenses, handling editors, and peer review.
Crossmark lets readers know when a substantial change affecting the citation or interpretation has occurred, and that the member has updated the metadata record to reflect the new status.
Watch the introductory Crossmark animation in your language:
Members can report updates to readers and showcase additional metadata.
Researchers and librarians can easily see the changes to the content they are reading, which licenses apply to the content, see linked clinical trials, and more.
Anyone can access metadata associated with Crossmark through our REST API, providing a myriad of opportunities for integration with other systems and analysis of changes to the scholarly record.
How Crossmark works
Members place the Crossmark button close to the title of an item on their web pages and in PDFs. They commit to informing us if there is an update such as a correction or retraction, as well as optionally providing additional metadata about editorial procedures and practices.
While members who implement Crossmark provide links to update policies and commit themselves to accurately reporting updates, the presence of Crossmark itself is not a guarantee. However, it allows the community to more easily verify how members are updating their content.
If you use Crossmark, the Crossmark button must be applied to all of your new content, not just content is updated. Selective implementation means that a reader, such as a research or librarian, who downloaded a PDF version before the update would have no way to know that it has been updated. We also encourage you to implement Crossmark for backfile content, although doing so is optional. At least, we encourage you to do so for backfile content that has been updated.
Obligations for Crossmark
Any member can provide update metadata and register an update policy. If you are a member who implements the Crossmark button, you must:
Maintain your content and promptly register any updates.
Include the Crossmark button on all digital formats (HTML, PDF, ePub).
Implement Crossmark using the script provided by us.
Not alter the Crossmark button in any way other than adjusting its size.
Implementing the Crossmark button involves technical changes to your website and production processes. Check that you have the necessarily expertise to implement these before you start. If not, you can start to deliver update metadata and implement the Crossmark button at a later point.
Any organisation can also implement the Crossmark button on pages where they display content. If you do so, you must follow the guidelines above, except for the first point if you are not reponsible for the content.
There are no additional fees to participate in Crossmark.
How to participate in Crossmark
There are several steps for members to fully implement Crossmark:
Devise an update policy, assign it a DOI, and register it with us.
Add the update policy and, optionally, other relevant metadata to your metadata records.
Publish corrections, retractions, and other updates for works where necessary, and register their metadata. See our guidance on registering updates.
Implement the Crossmark button online and in PDFs.
