Research Funders

PID strategies are being written around the world right now, and the decisions being made will shape the scholarly record for decades. After 25 years running open scholarly infrastructure—now on behalf of 25,000 members in 167 countries—Crossref has an informed perspective on what those decisions should ideally rest on. Today we’re setting it out in our’s first position paper: Persistent identifiers in research infrastructure policy: the need for a holistic approach. You can read it online or download the PDF; it’s a 16-minute read.

Funding is one of the key enablers of the research lifecycle, but has been one of the hardest parts of the scholarly record to identify, describe and connect. This is slowly changing as we have recently reached a very exciting milestone for Crossref’s Grant Linking System (GLS). What makes it remarkable is not only the numbers reached, but where the data comes from. Research funders, who joined Crossref as members, have actively contributed more than 200,000 grants to the Research Nexus (Figure 1).

For a funder with over thirty years of funding history, making all of their funding metadata openly available is no small undertaking. In this conversation, I chat with Guntram Bauer, Chief Scientific Officer at the Human Frontiers Science Program (HFSP), about how the organisation is working to register decades of grant data with Crossref, the challenges of linking historical awards to published research outputs, and what open, structured funding metadata means for accountability to member countries and the wider scientific community.

In April 2025, we launched the metadata matching project, in order to add missing relationships to the scholarly metadata. We will do this by consolidating all existing and planned matching workflows, which enrich member-deposited metadata in Crossref. This unified service will result in a more complete research nexus. In this blog post, we share our latest milestone: developing and evaluating a strategy for matching funder metadata to Research Organization Registry (ROR) identifiers.

We are pleased to announce that—effective 1st January 2026—we have made two changes to grant record registration fees that aim to accelerate adoption of Crossref’s Grant Linking System (GLS) and provide a two-year window of opportunity to increase the number and availability of open persistent grant identifiers and boost the matching of relationships with research objects.

In my latest conversations with research funders, I talked with Hannah Hope, Open Research Lead at Wellcome, and Melissa Harrison, Team Leader of Literature Services at Europe PMC. Wellcome and Europe PMC are working together to realise the potential of funding metadata and the Crossref Grant Linking System for, among other things, programmatic grantee reporting. In this blog, we explore how this partnership works and how the Crossref Grant Linking System is supporting Wellcome in realising their Open Science vision.

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.

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. 

We’re happy to note that this month, we are marking five years since Crossref launched its Grant Linking System. The Grant Linking System (GLS) started life as a joint community effort to create ‘grant identifiers’ and support the needs of funders in the scholarly communications infrastructure.

Some organisations at the forefront of adopting Crossref’s Grant Linking System presented their challenges and how they overcame them, shared the benefits they are reaping from participating, and provided some tips about their processes and workflows.

There is some overlap between the Open Funder Registry and the Research Organization Registry (ROR), and funders and publishers have been asking us whether they should use Open Funder Registry IDs or ROR IDs to identify funders when they appear in both registries. We aim to merge the two registries over time. We will ensure Crossref members can use ROR to simplify persistent identifier integrations, to register better metadata, and to help connect research outputs to research funders.
