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.
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”.
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.
Each organization in the global community of Crossref members (that’s currently over 24k organizations in 166 different countries) plays a key role in building the Research Nexus. Any opportunity we have to meet with our members in person is a highlight and a way for us to learn more from each other. The month of January saw three of us travel to Bangkok to attend the first-ever Charleston Conference organised in Asia and to meet with our growing community in Thailand.
Funders are joining Crossref to register their grants so that they can more easily and accurately track the outputs connected to the research they support.
Once you’re a member, registering grants with us means giving us information about each awarded grant, including a DOI which uniquely and persistently identifies each record. You can use the new Metadata Manager tool or direct XML deposit methods to deposit and update grant metadata. This section focuses on grants, but research funders can also register other record types such as reports, data, and working papers.
Decide which grants to register first, as you get into the swing of things. For example, pilot a particular country, or area of support. It’s better to start with newly-awarded grants, and then move on to older or long-running awards - these are cheaper to register, and are more likely to have produced research papers, so they’re great for demonstrating the full potential of connected research metadata.
A DOI is made up of a DOI resolver, a prefix, and a suffix. When you join Crossref as a member, we give you a DOI prefix. You combine this with a suffix of your choice to create a DOI. Although some funders choose to use their internal grant identifier as the DOI suffix, we advise you to make your suffix opaque, meaning that it does not encode or describe any information about the work. Your DOI becomes active once it is successfully registered with us. Read more about constructing your DOIs.
Should a grant move to a new landing page, the URL in the grant’s metadata is updated to point to the new location. There’s no charge to update metadata for existing deposits.
Grants can be registered for all sorts of support provided to a research group or individual, such as awards, use of facilities, sponsorship, training, or salary awards.
Here’s the section of our schema for grant metadata. If you’re working with a third-party system, such as Proposal Central or EuroPMC, they may be able to help with this piece of work.
Registering grant metadata using the grant registration form ``
You can use the grant registration form to register grants, with no prior knowledge of XML. You fill out the form and the XML is created for you in the background. You enter your account credentials and the metadata is submitted directly.
If you’d prefer to work directly with XML, you may be able to map your own data and identifiers to our schema. See our example deposit file - this is a full example, and many of the fields it contains are optional, but we encourage you to provide as much information as you can. Rich metadata helps maximum reuse of the grant records you register with Crossref. This .xsd file helps explain what goes into each field, and the parameters (length, format) of what is accepted in each field. Here’s a less techy version.
When you’ve created your XML files, use our checker to test them - this will show any potential errors with your files. For help with resolving problems, send your XML file and the error message to Support.
Once your submission is successful, your grant DOIs are ‘live’ and ready to be used. It’s good practice to add the grant DOI to the landing page for the grant, as in this example for https://doi.org/10.37717/220020589:
Let your grant submission systems, awardees, and other parties know you are supporting Crossref grant identifiers, and that they should start collecting these identifiers too. Crossref grant metadata (including grant DOIs) is made openly available through our APIs, so it can be used by third parties (including publishers, grant tracking systems) to link grants to related research outputs.
