Our REST API makes all of the metadata we hold publicly available. It receives the majority of our API traffic, with around 1 billion hits per month. It’s one of the key ways that we fulfil our mission to make research objects easy to find, cite, link, assess, and reuse. From 1 December 2025, we will be revising the rate limits for the public and polite pools of the REST API to ensure that we can maintain a stable and reliable system, and that metadata is freely available to everyone.
Noyam Journals, based in Accra, Ghana, was recently recognised for the completeness of its metadata through the Crossref Metadata Award, part of our 25th anniversary celebrations. Noyam was one of six publishers worldwide to receive the award and stood out as a leader among members of our Global Equitable Membership (GEM) Program.
Wednesday 22nd October 2025—Crossref, the open scholarly infrastructure nonprofit, today releases an enhanced dashboard showing metadata coverage and individual organisations’ contributions to documenting the process and outputs of scientific research in the open. The tool helps research-performing, funding, and publishing organisations identify gaps in open research information, and provides supporting evidence for movements like the Barcelona Declaration for Open Research Information, which encourages more substantial commitment to stewarding and enriching the scholarly record through open metadata.
Welcome back to our series of case studies of research funders using the Grant Linking System. In this interview, I talk with Cátia Laranjeira, PTCRIS Program Manager at FCCN|FCT, Portugal’s main public funding agency, about the agency’s approach to metadata, persistent identifiers, Open Science and Open Infrastructure.
With a holistic approach to the management, production and access to information on science, FCCN|FCT’s decision to implement the Grant Linking System within their processes was not simply a technical upgrade, but a coordinated effort to continue building a strong culture of openness. With the mantra “register once, reuse always”, FCCN|FCT efforts to embrace open funding metadata was only logical.
Our LIVE Annual Meeting is back in North America for the first time since 2015, and with just 10 days to go, there’s a lot going on in preparation. As you’d expect with a How good is your metadata? theme—the two-days will be entirely devoted to the subject of metadata—because it touches everything we do, and everything that publishers, hosting platforms, funders, researchers, and librarians do. Oh, and it’s actually super awesome too—and occasionally fun.
Metadata is what is used to describe the story of research: its origin, its contributors, its attention, and its relationships with other objects. The more machines start to do what humans cannot—parse millions of files through multiple views—the more we see what connections are missing, and the more we start to understand the opportunities that better metadata could offer.
We love metadata so much that we’re producing an 8-foot-high depiction of the ‘perfect’ record, in both XML and JSON, for people to gape at and annotate in person. Sneak preview:
The perfect metadata record is eight feet tall.

Both days feature plenary-style talks, insights from ourselves and guests who will regale us with tales of metadata woes and wonders.
Lisa will be there at the end of Day 1 to update everyone on some recent and potential governance changes, and—the reason we started these gatherings—to reveal the results of our 2018 board election, the second contested election we’ve held, and already with twice the voters from 2017.
Our amazing guest speakers are too brilliant and too experienced to highlight in just one blog. But check out the LIVE18 schedule to see what they’ll be talking about:
Patricia Cruse, DataCite
Ravit David, University of Toronto
Clare Dean, Metadata 2020
Paul Dlug, American Physical Society
Kristen Fisher Ratan, CoKo Foundation
Stefanie Haustein, University of Ottawa
Bianca Kramer, Utrecht University
Graham Nott, Freelance developer (eLife/JATS)
Jodi Schneider, University of Urbana-Champaign
Shelley Stall, American Geophysical Union
We’ll be taking over the entire second floor of the Toronto Reference Library, whose three rooms will house a bunch of conversational sessions as well as some more formal talks:
Rally is the main room where we’ll have the plenary-style talks, a corner for Unscheduled Maintenance offering live support for your questions about billing or tech for Ryan, Shayn, Isaac, Jason, Chuck, & Mike. Running down the whole left side of this room is also the You-are-Crossref wall where the community will showcase their work with metadata through posters - feel free to bring one along and find Patricia to get the sticky tack.
The LIVE Lounge is where you can eat, drink, rest, and chat and where you’ll likely find Rosa as she laises between the caterers, the venue, AV, and all of us. The Lounge is also where we’ll gather for much-needed post-election refreshments at the end of Tuesday.
The Bigger Ambitions Room is where a lot of the Unplugged sessions will take place. This room will feature three separate stations:
R&D & Product where you can chat with Geoffrey, Esha, Jennifer L, Patrick, and Christine about your big ideas for us, and what we’re working on already.
Metadata discussions and annotations of the perfect record (previewed above) with Patricia, together with space to ideate around metadata principles.
Uses and users of metadata where Jennifer K will help us understand just how far Crossref metadata can reach, and who and what people are doing with it.
We cannot wait to show you what else we have planned :-)
For those of you not able to attend, recordings of the presentations will be made available on the event page directly soon after.
