The Crossref Board recently approved three recommendations for changes to our fees: introduction of a new lowest membership fee tier, removal of volume discounts for record registration, and normalisation of registration fees for peer reviews. The changes will be applied from January 2026.
This is the first outcome of the Resourcing Crossref for Future Sustainability (RCFS) program, launched in 2023, as a comprehensive effort to review all aspects of Crossref revenue and how we’re adapting to growth and the diversification of our membership. The program aims to make fees more equitable, simplify our complex fee schedule, and rebalance revenue sources.
En 2025, lanzamos los Premios Crossref a los Metadatos, con el objetivo de destacar el rol de nuestra comunidad en la gestión y el enriquecimiento del registro académico. En esta publicación, destacamos a la Universidad La Salle, Perú, ganadora del premio a la excelencia entre los nuevos miembros, y contamos con la participación de Yasiel Pérez, Responsable Técnico y Editor de la Revista, quien comparte sus ideas:
This June, we presented at the Beijing International Book Fair (BIBF) and connected directly with our growing community in China. With a surge of interest from Chinese publishers and partners, it was clear: there’s a strong and rising curiosity around how metadata plays a vital role in maintaining the integrity of the scholarly record.
As a new Community Engagement Manager at Crossref, dedicated to working with the funders community, I frequently hear requests for examples and case studies of adopting Crossref’s Grant Linking System (GLS) by ‘funders like us’. This has spurred me to start a series of blog posts presenting funders’ perspectives on joining Crossref and using our system – to demonstrate how it’s done.
If you take a peek at our blog, you’ll notice that metadata and community are the most frequently used categories. This is not a coincidence – community is central to everything we do at Crossref. Our first-ever Metadata Sprint was a natural step in strengthening both. Cue fanfare!. And what better way of celebrating 25 years of Crossref?
We designed the Crossref Metadata Sprint as a relatively short event where people can form teams and tackle short problems. What kind of problems? While we expected many to involve coding, teams also explored documenting, translating, researching—anything that taps into our open, member-curated metadata. Our motivation behind this format was to create a space for networking, collaboration, and feedback, centered on co-creation using the scholarly metadata from our REST API, the Public Data File, and other sources.
What have we learned in planning
The journey towards the event was filled with valuable lessons and learnings from our community. Our initial call received submissions from 71 people, which was exciting but presented the first challenge: we felt our event would work better with a relatively smaller group. An additional challenge we faced was the enthusiasm from people from different regions of the world who were eager to join, but needed support to attend in person. It reminded us how global our community is, and how important it is to think about different ways of making participation possible, especially in future events.
We also wanted to make sure that participation wasn’t limited by technical background. The selection process included a preliminary review by several members of our team to bring in a mix of perspectives and reduce bias. The event welcomed participants from all kinds of expertise levels, including colleagues who had never worked with APIs before. We sought to provide common ground for all with several group calls, where we presented introductions to our tools and used the opportunity to collect requests about tools, specific data, and questions from the participants that could enhance their preparation during the sprint.
At the Crossref Metadata Sprint
I’ve recently stumbled upon the following quote from a recognized data scientist:
Numbers have an important story to tell. They rely on you to give them a clear and convincing voice. (Stephen Few) 1
It made me think that we can replace numbers for metadata and the idea still holds. Surrounded by the paleontological collections of the National Museum of Natural History, on 8th of April in Madrid, 21 participants and 5 Crossref staff came together to work on twelve different projects. These ranged from improvements to our Public Data file formats and exploring metadata completeness, to tackling multilingual metadata challenges, understanding citation impact for retracted works, and connecting Retraction Watch metadata with other knowledge graphs metadata.
The different teams that participated in the first Crossref Metadata Sprint.
The initial hours were the most energetic (but not chaotic!) as most of the participants had the chance to interact in person for the first time, ideas were exchanged, and pre-formed groups became more stable (however, one of the advantages of the format is that teams don't have to be rigid). Twelve coffee- and tea-powered projects started taking shape, a few of which are part of larger ideas under development. By the end of the second day, we saw:
Author changes between preprints and published articles.
Coverage of funding information by publisher.
Enriching citations with Crossref metadata.
Funding metadata completeness.
Improvement to the Public Data File.
Interoperability between Crossref DOIs and hash-based identifiers.
University of Tetova’s metadata coverage.
Retraction Watch data mash-up.
Perspective about AI-driven multilingual metadata.
Public Data File in Google Big Query.
Visibility of retractions across citations.
Visualising Crossref geographic member data.
Our team worked as part of some of these projects, providing valuable insights and feedback to the participants. We ended the first session with a group dinner and re-energised for the second day, which started with everybody fully immersed in their tasks. As we approached the conclusion, the groups started preparing some quick slides for a short presentation (that you can find here).
Our team and the participants left excited and looking forward to the next opportunity to collaborate. We certainly see the potential of recreating these spaces, and we’ll work on future editions in a different location. All of the project summaries and notes will remain stored in our metadata sprint Gitlab repo. Would you like to know more about any of these ideas? Let us know in the comments.

None of this would’ve been possible without our enthusiastic participants. Huge thanks to everyone! Here is the full list of those who attended our inaugural Sprint:
