Why metadata matters for research integrity: a new joint guide from Crossref and DataCite

Preserving the integrity of the scholarly record is an important component of the overall endeavour to protect research integrity. Open scholarly infrastructure enables persistent recording of research objects and associated metadata, which provides an evidence trail for these objects for all in the research community. Crossref and DataCite – as providers of essential infrastructure for preservation of the scholarly record – we share our joint expertise in the new guide on “Why metadata matters for research integrity and how to contribute”.

Strengthening community connections in São Paulo

Versão em português

As our global community continues to grow, it is important for us to build and maintain our connections within it. In March this year, we had the opportunity to visit São Paulo for a community event at the Fundação Getúlio Vargas. The content of our presentations is available online. Events such as this provide an opportunity for us to update our members on Crossref fundamentals and developments, and help us better tune in to the varied needs of our communities and learn how we can work together more effectively. This was our third visit to Brazil, with previous events held in Campinas and São Paulo in 2016, and Goiânia and Fortaleza in 2018. 

Voices from Crossref Metadata Sprint in São Paulo

This year, we placed a spotlight on the Latin American community, hosting the second Crossref Metadata Sprint in São Paulo, Brazil from 4 - 6 March 2026. In our first tri-lingual event, we brought together 31 participants from Argentina, Brazil, Colombia, Ecuador, and Mexico. Our goal was to foster community co-creation using the open scholarly metadata. The Sprint was an opportunity to pose questions, share ideas, collaborate on research, and propose innovative solutions that enhance the use of metadata in scholarly communication and beyond.

Read on for more details about the content of the Sprint, and the resulting projects. You can also register to join our Sprint Showcase call on 22nd April to hear directly from the team about their creations.

On metadata enrichment

Metadata is communication; it can tell a story about research and paint a picture for others to respond to and learn from, across the world and throughout the forthcoming generations. Metadata can feel technical with words like ‘infrastructure’ and ‘schema’, and sometimes, like tech in general, it comes with hyperbole. But metadata really is part art (storytelling and pictures) and part science (structured models and standards) with both aspects being equally important, and requiring people as well as systems. That necessary combination of human and machine involvement also makes metadata challenging.

2026 public data file now available

Once a year we release all metadata records for content registered with Crossref in a public data file. This year’s version, containing nearly 180 million records, is now available. It includes metadata associated with all Crossref-registered DOIs in JSON-lines format.

Insights from a roundtable on author affiliation metadata

It’s been said that Americans are unusual in tending to ask “Where do you work?” as an initial question upon introduction to a new acquaintance, indicating a perhaps unhealthy preoccupation with work as identity. But in the context of published research, “What is this author’s affiliation?” is a question of global importance that goes beyond just wanting to know the name – and perhaps prestige level – of the place a researcher works.

The best way of acknowledging research funding in the metadata: Crossref Grant ID

We are very pleased to kick off the New Year with another important schema update and the news that a Grant DOI field is now supported for all record types. This means that Crossref members can explicitly include the Crossref Grant IDs as part of their DOI metadata records for publications and any other output type, accurately linking research outputs to the funding that made it possible, all through metadata. We hope that our members will leverage this to respond to recent calls for stronger funding transparency and best practices for reporting funding sources in research outputs

Highlights of a very busy year: our 2025 annual report

As we finish celebrating our 25th anniversary, we can look back on a truly transformational year, defined by the successful delivery of several long-planned, foundational projects—as well as updates to our teams, services, and fees—that position Crossref for success over the next quarter century as essential open scholarly infrastructure. In our update at the end of 2024, we highlighted that we had restructured our leadership team and paused some projects. The changes made in 2024 positioned us for a year of getting things done in 2025. We launched cross-functional programs, modernised our systems, strengthened connections with our growing global community, and streamlined a bunch of technical and business operations while continuing to grow our staff, members, content, relationships, and community connections.

Metadata in editorial workflows

Background

Scholarly metadata, deposited by thousands of our members and made openly available can act as “trust signals” for the publications. It provides information that helps others in the community to verify and assess the integrity of the work. Despite having a central responsibility in ensuring the integrity of the work that they publish, editorial teams tend not be fully aware of the value of metadata for integrity of the scholarly record. How can we change that?

Announcing changes to REST API rate limits

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.
